Influence of Detail Level in Acoustic Modeling of Heritage Buildings. Case of the Lonja de los Mercaderes in Valencia
Get PDFAcoustic modeling of heritage buildings presents a significant challenge due to the architectural complexity of these spaces and the need to preserve their authenticity. In particular, the precision of the virtual model in historical environments largely depends on the level of detail applied during simulation. This study examines the influence of detail level in acoustic modeling applied to the Lonja de los Mercaderes in Valencia, a prominent example of Gothic civil architecture in Europe. Using ODEON software, three virtual models of the main hall were developed with varying levels of detail, from a high-precision model to a simplified representation. The results show that a highly detailed model increases computational costs, while a reduction in detail leads to greater dispersion in results, especially at low frequencies. This research highlights the importance of finding an appropriate balance in detail level, providing reliable acoustic estimates without compromising efficiency. These findings contribute to ongoing discourse on heritage conservation practices, emphasizing how simulation technologies can aid in preserving acoustic integrity while addressing practical limitations. The conclusions have implications for the application of simulation technologies in other highly complex heritage buildings.La modellazione acustica degli edifici storici rappresenta una sfida significativa a causa della complessità architettonica di questi spazi e della necessità di preservarne l'autenticità. In particolare, la precisione del modello virtuale in ambienti storici dipende in larga misura dal livello di dettaglio applicato durante la simulazione. Questo studio esamina l'influenza del livello di dettaglio nella modellazione acustica applicata alla Lonja de los Mercaderes di Valencia, un importante esempio di architettura gotica civile in Europa. Utilizzando il software ODEON, sono stati sviluppati tre modelli virtuali della sala principale con diversi livelli di dettaglio, da un modello ad alta precisione a una rappresentazione semplificata. I risultati mostrano che un modello altamente dettagliato aumenta i costi computazionali, mentre una riduzione del dettaglio porta a una maggiore dispersione dei risultati, soprattutto alle basse frequenze. Questa ricerca sottolinea l'importanza di trovare un equilibrio adeguato nel livello di dettaglio, fornendo stime acustiche affidabili senza compromettere l'efficienza. Questi risultati contribuiscono al dibattito in corso sulle pratiche di conservazione del patrimonio, enfatizzando come le tecnologie di simulazione possano aiutare a preservare l'integrità acustica affrontando al contempo le limitazioni pratiche. Le conclusioni hanno implicazioni per l'applicazione di tecnologie di simulazione in altri edifici storici di elevata complessità
Aproximaciones al paisaje arqueológico en las tierras bajas sudamericanas: un estudio SIG en el noreste de Buenos Aires (Argentina)
Get PDFRegional archaeological research focusing on landscape was developed in the southern sector of Punta Indio (northeast of Buenos Aires province, Argentina). That sector, which covers an area of 722 km2 (Figure 1), had limited archaeological backgrounds. During fieldwork, systematic prospections were performed, by which four sites linked to hunter-gatherer groups were registered: Los Tres Ombúes, El Puesto, Don Enrique and Corral del Indio (Figure 2), of which the first two were excavated. By integrating the obtained data, it was made possible to understand this sector as a part of the landscape inhabited by hunter-gatherer groups in the Late Holocene (1110-260 years C14 BP; 982-1796 years cal.). This article, on the one hand, aims to present the results of several analyses performed through Geographic Information Systems (GIS), based on original spatial information obtained by an archaeological approach at the southern sector of Punta Indio, as well as its regional context. On the other hand, it focuses on discussing the contributions of this approach to the research of the Late Holocene archaeological landscape in the northeast of Buenos Aires province (Argentina).
The methodological strategy consisted of complementary GIS-based analyses: visibility, mobility, and suitability areas estimation. Three scales were defined for these analyses: the archaeological site, a local study sector and a wider area of 12.000 km2 corresponding to the regional scale.
For each considered site, visibility conditions and accessibility to the immediate surroundings were analysed. Regarding visibility, results showed similarities between Los tres Ombúes and Don Enrique, both located on the Río de la Plata coastal plain. From these places, a large portion of the plain is potentially observable. In addition, the visibility conditions of the sites linked to the Samborombón river -El Puesto and Corral del Indio- encompass the watercourse and its surroundings, including the mouths of tributary streams and nearby lagoons (Figure 3). The accessibility to the last sites immediate surroundings proves there was easy access to the river in half an hour duration routes. Moreover, the sites of the Rio de la Plata coastal plain evidence immediate access to the estuarine coast, as well as to minor courses that flow here (Figure 4). According to the obtained model, the distances, easy to walk within half an hour to three hours, could imply access to neighbouring sites. The archaeological places considered for this study are separated from each other by longer distances. However, some of these show relations with others in the area. As the accessibility maps indicate, all the long-range mobility isochrones imply a wider reach than the study sector.
Also, the formulation of transit areas from the optimal routes obtained by GIS (Figures 5-6) allowed us to inquire about the sector mobility and the wider area involving the integration of obtained results with the archaeological knowledge of adjacent areas. The transit areas show the importance that the Río de la Plata estuary and the Samborombón river coastlines, as the Salado river coast, could have had for the human groups’ mobility. In addition, a multicriteria evaluation with regional scope (Figure 7, Tables 1-2) allowed us to obtain a present-day location aptitude model of the inhabited places in the landscape; consequently, it was possible to explore the environment variables possibly linked to the settlement modalities.
Even though archaeological sites are located in some of the higher altitude points in the landscape, the sample does not show a strong influence of the net altitude (Figure 8). Therefore, relative altitude regarding the close surroundings could have had a bigger influence on the site's location. The places showed good visibility conditions and good accessibility to the immediate surroundings, which imply watercourses and bodies that were possibly travelled during the inhabitants’ daily activities. They could have also been linked in mobility nets related to social interaction networks inferred for these groups, which could have mutually visited with different and multiple purposes. According to suitability areas estimation, the sector sites are related to very suitable conditions. That is also verified in the wider area, where the distribution shows a strong link with very suitable locations, near watercourses and bodies or to the Río de la Plata coastline.
As the Samborombón and Salado rivers eventually suffered water excesses, possibly the regional mobility could have had a seasonal component. Also, results suggest that the coast constituted a main route in the northeast of Buenos Aires. Even though the coastline is highly dynamic and presents an accessible and inaccessible sectors alternation, there are nearby shell ridges -longitudinal elevations that probably facilitated human movement in the past.
GIS-based methods essentially helped to understand the Late Holocene archaeological landscape in the northeast of Buenos Aires. This enabled an original interpretation of the landscape considering four factors: the characteristics of the inhabited places, the practices of the hunter-gatherer groups, the settlement modalities and the movements of those groups across the landscape. Consequently, the authors highlight their potential for hunter-gatherer research in South American lowlands contexts.La investigación arqueológica regional enfocada en el paisaje fue realizada en el sector meridional del partido de Punta Indio (noreste de la provincia de Buenos Aires, Argentina). En este sector de 722 km2, que contaba con escasos antecedentes arqueológicos, se realizaron prospecciones en las cuales fueron registrados los sitios Los Tres Ombúes, El Puesto, Don Enrique y Corral del Indio. La integración de los datos obtenidos posibilitó la comprensión del sector como parte del paisaje habitado por grupos cazadores-recolectores en momentos del Holoceno tardío (1110-260 años C14 AP; 982-1796 años cal.), con una notoria participación en redes regionales de interacción social. Este artículo tiene por objetivo, por una parte, presentar el análisis de la información espacial resultante del abordaje arqueológico del sector meridional del partido de Punta Indio y su integración regional, realizado mediante Sistemas de Información Geográfica (SIG); por otra parte, discutir su aporte al estudio del paisaje arqueológico del Holoceno tardío en el noreste de la provincia de Buenos Aires (Argentina). El análisis implicó tres escalas: el sitio arqueológico, el sector de estudio y la escala regional (recorte espacial de 12.000 km2). En primer lugar, se abordaron la visibilidad y la accesibilidad al entorno inmediato para cada sitio. También se establecieron áreas de tránsito que permitieron indagar la movilidad en el sector y para una escala más amplia, lo cual implicó integrar los resultados obtenidos con el conocimiento arqueológico relativo a las áreas vecinas. Asimismo, fue realizada una evaluación multicriterio de alcance regional, la cual permitió generar un modelo actualístico de aptitud respecto a la localización de los lugares habitados. Se destaca el aporte de los SIG al estudio arqueológico de los grupos cazadores-recolectores en contextos de tierras bajas, al propiciar la interpretación de las estrategias para habitar el paisaje implementadas por dichos grupos
Estudio de deformaciones y degradaciones mediante el uso de nubes de puntos en la natatio de las Termas Occidentales de La Alcudia en Elche (Alicante)
Get PDFThis paper deals with the study of construction and geometry, as well as with the analysis of deformations and active degradations of the natatio belonging to the Western Baths in La Alcudia archaeological site. Its location in Elche-Alicante, Spain (Colonia Iulia Ilici Augusta), is widely known for the discovery of The Lady of Elche in 1897. The dimensions of this natatio in the frigidarium are 6.60 x 9.30 m (22 x 31 Roman feet) and 1.50 m deep, making it one of the largest Roman swimming pools documented to date on the Iberian Peninsula. The natatio has several cracks sealed with materials used in earlier interventions at the end of the third century. Its comparison with the hypothetical original form allowed the researchers to quantify the current deformations. A damage evolution study has been made comparing the 2016 point cloud with the 2022 cloud, both obtained by light detection and ranging (LIDAR). There is evidence that an active process of degradation and deformation is gradually increasing damage to the pool. By studying the geometry and constructive systems of the natatio, relevant data to understand the historical evolution of the Western Baths have been provided. A results analysis conclusion is that the pool was built in two different stages. The eastern half corresponds to the original natatio, while the western half was extended or rebuilt after having collapsed. The early abandonment of the use of the natatio was most likely due to deformations caused by differential settlement; this occurred when the western half was cemented on landfill between the ancient wall and that of the last third of the 1st century AD.El presente trabajo aborda el estudio de la construcción y geometría, así como el análisis de las deformaciones y degradaciones activas que presenta la natatio perteneciente a las Termas Occidentales del yacimiento arqueológico de La Alcudia, en Elche, Alicante (Colonia Iulia Ilici Augusta); éste es conocido internacionalmente por el hallazgo de la Dama de Elche en 1897. Las dimensiones de esta natatio del frigidarium, 6.60 x 9.30 m (22 x 31 pies romanos) y 1.50 m de profundidad, la convierten en una de las piscinas para baños fríos de época romana más grandes de las documentadas hasta la fecha en toda la península Ibérica. La natatio presenta varias grietas selladas con materiales empleados en intervenciones anteriores a finales del siglo III. Los resultados obtenidos al realizar el estudio comparativo con su hipotética forma original han permitido cuantificar sus deformaciones actuales. Se ha realizado un estudio de evolución de daños comparando la nube de puntos obtenida en el año 2016 con la nube realizada en el año 2022, ambas obtenidas mediante LIDAR (light detection and ranging). Se ha evidenciado que existen degradaciones y deformaciones activas que paulatinamente van aumentando los daños en la natatio. El estudio de la geometría y de los sistemas constructivos de la natatio también han aportado datos relevantes para la comprensión de la evolución histórica del conjunto de las Termas Occidentales. Del análisis de los resultados de este estudio se concluye que la actual natatio se construyó en dos fases diferentes. La mitad oriental coincide con la natatio original y la mitad occidental se amplió o se reconstruyó tras arruinarse. El temprano abandono del uso de la natatio se debió, con toda probabilidad, a las deformaciones provocadas por asientos diferenciales al cimentar la mitad occidental sobre terrenos de relleno entre la muralla antigua y la del último tercio del siglo I
Aplicación de métodos de virtualización en arqueología: el caso de la estela A de la tumba de Henenu (TT 313, Deir el-Bahari, Egipto)
Get PDFThis paper aims to demonstrate how the combination of digital methods for virtual reconstruction is valuable both for knowledge dissemination and for its application in research. Through the case study of the tomb of Henenu (TT 313: Deir el-Bahari, Luxor), this paper shows that the virtual reconstruction techniques constitute a very powerful tool to test hypotheses. Based on this objective, namely the testing of several hypotheses about the dimension and location of various tomb stelae, the authors explain the workflow used during the reconstructing process of these stelae found in the tomb of Henenu and suggest their originally intended setting within the tomb.
Hundreds of stelae fragments were found by the New York Metropolitan Museum of Art archaeological expedition between 1922 and 1923. Upon these discoveries, archaeologists decided to reconstruct four stelae, emphasising stela A, whose quality attests for its relevant position in the monument. William Hayes identified four different stelae on the basis of the rock types, the stelae fragments thickness, the edge types (curve-edged vs. flat-edged), as well as the iconographic and inscriptional materials attested through the fragments. In 2015, the Middle Kingdom Theban Project (MKTP) continued with the previous works in the area and initiated the recovery of hundreds of fragments from the tomb of Henenu, some of them previously unattested. Once the archaeological and architectural data were collected, the MKTP specialists proceeded to calculate and reconstruct the four stelae dimensions through digital means. In addition, the researchers tested whether these four stelae fit the rock-cut niches identified for their original location. All of them were located in the tomb main corridor leading to the public cultic area within the rock-cut tomb. The following pages describe the workflow used in this process, expanding from the tomb cleaning and laser scanning to digital documentation and modelling. For this project, the architects of the team used the laser scanner Faro Focus 3D to document Henenu’s tomb, including the corridor leading to its cultic chamber, as well as the tomb restricted (sacred) areas (i.e., burial chambers and shafts). The data obtained was subsequently processed in Leica Cyclone to obtain a mesh. However, the resulting mesh was not sufficiently clean as it presented some noise. Noise consists of anomalies generated during the scanning process, and it is critical to achieve the most accurate result. The cleaning process was carried out in different software. The outcome was then imported into the Blender modelling software. This result enabled the researchers to create a virtual model of Henenu’s stela A, which was then textured using the Substance Painter software. For this procedure, specialists searched for ancient Egyptian limestone stelae examples with similar textures. In the final phase, Photoshop and Substance Painterwere combined, which was key for reproducing the details of the inscription carved in the stela A. The stela major topic is the provision of offerings to the deceased and the guarantee of benefactions for the deceased; this explains why the presumable niche for this object was just at the entrance of the tomb.
The ancient Egyptian findings reconstruction is an essential part of the archaeological, epigraphic, and conservation initiatives conducted by the MKTP in the cemeteries of Deir el-Bahari and Asasif (Luxor, Egypt). This multidisciplinary international project seeks to continue with the excavation, documentation, and publication of the archaeological, artistic, and material finds dating to the Eleventh and Twelfth dynasties in the Theban necropolis. Thanks to the virtual reconstruction and to the study of the related data, scholars were able to choose one of the initial reconstruction and location hypotheses of these stelae, providing an answer to the initial question of the project, particularly in the case of stela A.Highlights:
La combinación de diversos métodos digitales para la reconstrucción virtual es una poderosa herramienta para la difusión y la investigación del patrimonio arqueológico.
El trabajo con cientos de fragmentos hallados en la tumba de Henenu ha permitido la reconstrucción virtual de cuatro estelas funerarias, con especial detalle en el caso de la estela A.
Las hipótesis, cálculos e interpretaciones derivadas de estas reconstrucciones virtuales han contribuido a identificar la posición inicial de estas estelas en el monumento.
Resumen:
Este trabajo pretende demostrar cómo la combinación de métodos digitales para la reconstrucción virtual en arqueología es mucho más que una simple herramienta para la difusión del patrimonio. A través del estudio de la tumba de Henenu (TT 313: Deir el-Bahari, Luxor), este artículo demuestra que los métodos de reconstrucción virtual constituyen una herramienta eficaz para examinar diversas hipótesis. Cientos de fragmentos de estelas fueron encontrados por la expedición del Museo Metropolitano (Nueva York) en 1922-1923. Tras este descubrimiento, los arqueólogos reconstruyeron cuatro estelas, destacando la estela A. Una vez recuperados los datos arqueológicos y arquitectónicos, los especialistas del MKTP procedieron a reconstruir las posibles dimensiones de estas estelas mediante técnicas digitales. Además, se examinó si las estelas encajaban en los nichos originales construidos para este propósito. En este artículo se plantea el flujo de trabajo empleado desde el escaneado láser hasta el modelado de las estelas, usando un escáner láser para documentar la tumba. Los datos fueron procesados con Leica Cyclone para obtener una malla, aunque la malla presentaba algo de “ruido”, anomalía que debió ser corregida con otro software. El resultado fue entonces exportado a Blender. De este modo se consiguió la reconstrucción virtual de la estela A de Henenu, que recibió texturas y otros rasgos con Substance Painter y Photoshop. El tema principal de la estela es la provisión de ofrendas y la garantía de beneficios para el difunto, lo que explicaría que el nicho de erección de la estela estuviera a la entrada de la tumba. Como se describe en las conclusiones, gracias a la aplicación de las técnicas de reconstrucción virtual y a los cálculos derivados de la misma, se ha podido elegir una de las hipótesis de reconstrucción y localización de las estelas, ofreciendo una respuesta a la pregunta inicial que se planteaba sobre el caso de la estela A
Regreso a Cosa (Ansedonia, Italia): contribuciones de las imágenes SAR-X procedentes del satélite PAZ en la prospección arqueológica no invasiva
Get PDF Highlights:
Some archaeological results obtained using SAR-X images received through the PAZ satellite and applied to a part of what was called Ager Cosanus are shown in this article.
The study has been completed with the analysis of multispectral images TripleSAT and Sentinel-2A and the historical aerial photos from 1944 and 1954.
The possibilities of using PAZ images treated multi-temporally as a high-resolution panchromatic image applicable to multispectral optical images of the type Sentinel-2 were tested.
Abstract:
Some archaeological results are shown in this article, which have been generated from the use of Synthetic Aperture Radar (SAR)-X images obtained from the PAZ satellite and applied to part of what was called Ager Cosanus, that is, the territory of the city of Cosa, which was one of the first maritime colonies of Rome in the heart of Etruscan territory. Our study has been carried out mainly based on previous works in which a set of images was used to improve the quality of the resulting image, reducing the noise caused by the speckle of the radar images and maintaining the quality of the spatial resolution that can be obtained from these images (1.25 m/pixel). More specifically, a set of images obtained between 2019 and 2021 was used. The study has been completed with the analysis of multispectral images TripleSAT and Sentinel-2A, the historical aerial photos taken from 1944 and 1954, and the use of the historical cadastre of Tuscany, prepared at the beginning of the 19th century. As an addition, the Digital Terrain Model (DTM) Light Detection And Ranging (LiDAR) of the Region of Tuscany was used, on which various functions of the Relief Visualization Tool (RVT) programme have been applied, complementing or contrasting the results. It can be confirmed that the multi-temporal treatment of SAR PAZ images provides better results than an individualised analysis of the image. Finally, it is of great interest to verify the results of studies using new technologies, where it was previously possible to resort only to prospecting on the ground and to analogical aerial photography in black and white. In this case, the Sinistra Decumano I (SDI) structure was seen, which Castagnoli observed in the aerial photography, but of which he only located materials on the ground and it was visualised both in individualised PAZ images and in Sentinel-2.Este artículo muestra algunos resultados arqueológicos generados a partir del uso de imágenes SAR-X obtenidas a través del satélite PAZ y aplicadas a una parte de lo que se denominó ager cosanus, es decir, el territorio de la ciudad de Cosa, que fue una de las primeras colonias marítimas de Roma en el corazón del territorio etrusco. Nuestro estudio se ha realizado principalmente a partir de trabajos previos en los que hemos utilizado un conjunto de fotografías para mejorar la calidad de la imagen resultante, reduciendo el ruido provocado por el moteado de las imágenes de radar y manteniendo la calidad de la resolución espacial que se puede obtener de las mismas (1.25 m/píxel). En concreto, se ha trabajado con un conjunto de imágenes obtenidas entre 2019 y 2021. El estudio se ha completado con el análisis de imágenes multiespectrales TripleSAT y Sentinel-2A, las fotos aéreas históricas tomadas a partir de 1944 y 1954, y la utilización del catastro histórico de la Toscana, elaborado a principios del siglo XIX. De forma complementaria, se ha trabajado con el Modelo Digital del Terreno (MDT) LiDAR de la Región de Toscana, sobre el que se han aplicado diversas funciones del programa Relief Visualization Tool (RVT), complementando o contrastando resultados. Podemos confirmar que el tratamiento multitemporal de las imágenes SAR PAZ proporciona mejores resultados que un análisis individualizado de la imagen. Por último, resulta de gran interés el comprobar cómo la utilización de imágenes PAZ y Sentinel-2A permiten la revisión de resultados de estudios anteriores, en los que sólo era posible recurrir a la prospección sobre el terreno y a la fotografía aérea analógica en blanco y negro, como en el caso que aquí se presenta, donde se analiza una de las estructuras de parcelario romano, la Sinistra Decumano I (SDI) del ager cosanus, localizada y publicada por Castagnoli en 1993

Abstract:
Cultural heritage encompasses both tangible and intangible aspects for each of us, and efforts must be made to safeguard this legacy for future generations. Unfortunately, in addition to natural and environmental degradation, human activities pose a significant threat to the integrity of historical sites. Monuments and architecture have frequently been intentionally destroyed in conflict zones all over the world. Three-dimensional (3D) and virtual technologies can serve as tools to digitally preserve these sites and raise awareness about the importance of historical properties to the general public, particularly when physical sites are at risk or no longer exist. This challenging field of lost heritage is the framework of this project, in which a procedure of geomatics-based techniques such as spherical photogrammetry, 3D modelling and virtual reality (VR) technologies was developed to reconstruct lost historical architecture. The Roman Theatre in Palmyra, Syria, partially destroyed during Syria’s war in 2017, serves as a case study. The methodology report starts with the description of the metrological foundation of the 3D model construction, i.e. spherical photogrammetry as developed by Prof. Fangi (Marche Polytechnic University). Then, the geometry optimisation phase carried out to accomplish the VR limitations in terms of polygon count is presented. Ultimately, the procedure for the virtual environment construction is explained, as well as the development of a metaverse scenario to be visited and shared on an online-based platform. This collective virtual experience aims to revive the destroyed architecture and communicate its significance to the public through a collective and interactive virtual exploration. This study also includes experiments to assess user response, providing insights into methodology effectiveness in conveying Palmyra’s Theatre historical relevance and shedding light on the users’ perceptions of virtual tools usage for lost heritage dissemination. The evaluation questionnaire’s results will guide the project’s future developments.El patrimonio cultural incluye aspectos tangibles e intangibles y es esencial proteger este legado a futuras generaciones. Sin embargo, además de la degradación medioambiental, las actividades humanas representan una amenaza en los sitios históricos. Con frecuencia, los monumentos y la arquitectura son destruidos en zonas de conflicto. Las tecnologías 3D y virtuales pueden ser herramientas valiosas que preserven digitalmente estos lugares y sensibilicen al público sobre su importancia, especialmente cuando los sitios físicos están en peligro o ya no existen. Este campo del patrimonio perdido es el enfoque del proyecto, en que se ha desarrollado un procedimiento de técnicas geomáticas, como es la fotogrametría esférica, el modelado 3D y la realidad virtual (RV) que reconstruye la arquitectura histórica perdida. El Teatro romano de Palmira (Siria), parcialmente destruido durante la guerra siria de 2017, representa el caso de estudio. El informe metodológico comienza describiendo la base metrológica del modelo 3D, a partir de la fotogrametría esférica desarrollada por el profesor Fangi (Universidad Politécnica de Marche). Luego, se detalla la fase de optimización de la geometría que cumple con las limitaciones de la RV en términos de polígonos. Finalmente, se explica el procedimiento de construcción del escenario virtual y el desarrollo de una experiencia de metaverso que se podrá visitar y compartir en una plataforma online. Esta experiencia colectiva busca revivir la arquitectura destruida y comunicar su significado al público a través de una exploración virtual interactiva. El estudio incluye experimentos que evalúan la respuesta de los usuarios, proporcionando información sobre la eficacia de la metodología para transmitir la relevancia histórica del Teatro de Palmira y las percepciones sobre el uso de herramientas virtuales en la difusión del patrimonio perdido. Los resultados del cuestionario guiarán la evolución futura del proyecto, mejorando su capacidad para sensibilizar y educar al público sobre la importancia de nuestro patrimonio cultural

Aprendizaje automático en el diagnóstico médico. Un caso de estudio en la identificación del Trastorno del Espectro Autista a partir del comportamiento ocular
Get PDFDespite recent advances, autism diagnosis remains a complex challenge due to the need for specialized medical resources, time, and materials. This often leads to late diagnoses, even in adulthood, hindering effective interventions. On the other hand, the field of artificial intelligence and machine learning has seen remarkable progress. These techniques have opened up new opportunities in various areas, including medical diagnosis and Autism Spectrum Disorder (ASD). The primary objective of this article is to provide a general overview of the applicability of machine learning techniques in medical diagnosis, using a specific case of ASD as an example. A classification model based on the XGBoost algorithm has been developed, achieving a sensitivity of 82 % and a specificity of 74 % when classifying individual samples. Furthermore, by combining this model with a majority voting algorithm, highly noteworthy classification results are obtained in the test set.A pesar de los avances recientes, el diagnóstico del autismo sigue siendo un desafío complejo debido a la necesidad de recursos médicos especializados, tiempo y materiales.
