Statistical learning and convolutional neural networks for supervised and unsupervised restoration of satellite images in low light conditions.
No full textEste manuscrito es el resultado de la pasantía de fin de carrera de Manuel Sánchez Laguardia como parte de sus estudios de ingeniería en el IMT Atlantique y la Universidad de la República.This manuscript is the result of Manuel Sánchez Laguardia’s end-of-studies internship as part of his engineering studies at IMT Atlantique and Universidad de la República. The development of this work began the 1st of April 2023 and extended until the 30th of September 2023, for a total duration of six months. The internship was carried under the mentorship of Charles Kervrann and Emmanuel Moebel. It covered two main projects, both related to the subject of this internship: "Statistical learning and convolutional neural networks for supervised and unsupervised restoration of satellite images in low light conditions" This document is divided into 7 main Sections. First, the introduction to the mission, where the context, background and expected results are explained. Then, the presentation of the hosting organization. Next, the developed work and methodology, where the two main projects are presented in separate Sections. Then, the conclusions followed by the perspectives of the project. Finally, a reflection on my professional project for the future and its link with this internship. The first project consisted in studying the statistics behind the gradient descent used to estimate parameters of convolutional neural networks. This was achieved via the study of a well-known machine learning algorithm used for denoising: Deep Image Prior [1]. This analysis gave very interesting results. It showed that the direction of the parameters vector of the neural network throughout the iterations, could be explained almost entirely with just one PCA (Principal Component Analysis) vector. However, it also showed that from one iteration to the next, the parameters change almost randomly, and no information could be extracted from them as whole. This first project was set aside to be worked on, possibly, towards the end of the internship. The second project consisted in performing image restoration methods by combining denoising and deconvolution, using different techniques. I focused on satellite images in low light conditions, as this is what the team has been working since they partnered up with Airbus Space and Defense. The goal was to explore how this different methods performed, and draw conclusions in terms of performances (PSNR) and time computations. It was found that the type of noise had a high impact on the result of the methods. Also, it was shown experimentally that training one of the supervised methods using microscopy images, which are similar to night satellite images, produces very good results and are a good fit for the training phase

Can reforming global institutions help developing countries share more in the benefits from globalization?
No full textGlobalization could significantly expand trade, international investment, and technological advances, but the gains from global integration have been unevenly distributed across and within nations. Greater global interdependence has also brought greater macroeconomic volatility, resulting in several serious financial crises in the second half of the 1990s. The global matrix of Bretton Woods and United Nations institutions that developed starting in the 1940s, formed under a different balance of power, in a world of fixed exchange rates and limited capital mobility. Since the 1960s regional financial institutions have emerged because of the greater autonomy of different regions and the greater financial needs of development. The author reviews different proposals for reform of the international financial institutions and changes in the roles of the International Monetary Fund (IMF) and the World Bank. He highlights the implications for developing countries of (1) Policy conditionality. (2) The countercyclical role of multilaterals'lending. (3) Greater lending to middle-income than to low-income developing countries. (3) Access to liquidity at times of crisis. (4) Mechanisms for giving low-income countries a greater voice in IMF and World Bank decisionmaking. The author streses the overlapping responsibilities of the Bretton Woods and regional financial institutions and the need to reassess the allocation of responsibilities and to develop better coordination mechanisms between these institutions. Those designing institutional reform must consider the corporate capabilities of each type of institution. The corporate cultures of global and regional institutions differ. So does the kind of knowledge they generate and disseminate, and so do patterns of interactions with, and mechanisms for representation of, client countries.Finally, the author calls attention to the need to harmonize national and global growth-oriented policies in a way that reduces volatility and promotes social equity.Environmental Economics&Policies,Governance Indicators,Financial Intermediation,Economic Theory&Research,Banks&Banking Reform
A formação de professores em e para direitos humanos na perspectiva filosófica de Emmanuel Levinas
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Educação, Programa de Pós-Graduação em Educação, Florianópolis, 2013.O presente trabalho tem como proposta refletir a formação de professores em e para direitos humanos na perspectiva filosófica de Emmanuel Levinas. Este autor propõe a ética como filosofia primeira, uma vez que a concebe como resposta à interpelação do Outro. Ela seria um caminho para resistir à ontologização e, consequentemente, à totalização. A ética levinasiana origina-se no reconhecimento da alteridade do Outro, sendo o rosto a manifestação da singularidade de cada pessoa, motivo pelo qual todo ser humano é possuidor de dignidade, um dos fundamentos dos direitos humanos. A relação ética Eu-Outro, bem como com terceiros (estrangeiro) é assimétrica, pois, desestabiliza e exige dos sujeitos dialogantes abertura, acolhimento e responsabilidade, emergindo daí a necessidade de pensar uma política na perspectiva da outridade. Portanto, uma proposta formativa pensada e articulada a partir do reconhecimento da alteridade faz irromper o inesperado, o imprevisível da vida que viria questionar concepções e práticas formativas que subordinam e colonizam o Outro, reduzindo-o ao Mesmo. Neste sentido, ainda que se reconheça a complexidade quanto à fundamentação filosófica dos direitos humanos, é intransferível a responsabilidade de pensar a formação de professores em uma perspectiva de uma pedagogia da alteridade, justificando-se assim a relevância da abordagem a qual nos propomos. Por isso, uma formação em e para direitos humanos na perspectiva filosófica de Levinas tem de ter seu fundamento na interpelação ética do Outro, cujos encaminhamentos curriculares e metodológicos se constituem em respostas aos seus apelos. Esta formação não possui encerramento em uma cerimônia de colação de grau, pois se caracteriza como inacabamento, incompletude e constante abertura à novidade que se manifesta no rosto do Outro, exigindo outros tempos, espaços, currículos e metodologias para processos formativos emancipadores. Este trabalho é de cunho qualitativo e está organizado em cinco momentos: no primeiro apresentamos o contexto e a introdução à temática da formação e dos direitos humanos; no segundo momento, tratamos da complexidade que entorna o conceito de direitos humanos; no terceiro, abordamos o pensamento levinasiano, especialmente as categorias alteridade, responsabilidade e interpelação ética; no quarto momento, refletimos os desafios e possibilidades de pensar a formação de professores na perspectiva da ética e pedagogia da alteridade e; finalizamos com algumas considerações que percebemos como necessárias, reconhecendo várias aberturas para possibilidades futuras de pesquisas, estudos e reflexões. Abstract : This present work aims to reflect the teachers education in and for human rights in the philosophical perspective of Emmanuel Levinas. This author proposes ethics as first philosophy, once conceives it as a response to the interpellation of the Other. It would be a way to resist to the ontologization and hence aggregation. Levinasian ethics originates in the recognition of the otherness of the Other, being the face, the manifestation of the uniqueness of each person, which is because every human being is possessed of dignity, one of the foundations of human rights. The ethical relation me - Other, and with third parties (foreign) is asymmetric because destabilizes and requires from the subjects dialoguers openness, acceptance and responsibility, emerging hence the need for a policy thinking from the perspective of othernes. Therefore, a training proposal conceived and articulated from the recognition of otherness does erupt the unexpected , the unpredictable of life and it would come to question concepts and training practices that subordinate and colonize the Other , reducing him to the Same . In this sense, although it recognizes the complexity as the philosophical foundation of human rights, is non-transferable responsibility of thinking about teacher education in a perspective of alterity pedagogy, thus justifying the relevance of the approach which we propose. Therefore, training in and for human rights in Levinas philosophical perspective, must have its foundation in ethical interpellation of the Other, whose curricular and methodological referrals constitute responses to their requests. This training does not have closure in a graduation ceremony, because it characterizes itself as unfinished, incompleteness and constant opening to novelty manifested on the face of the Other, requiring other times, spaces, curricula and methodology for emancipatory educational processes. This work is a qualitative one and it is organized into five parts: the first presents the context and introduction to the theme of education and human rights, in the second moment, we deal with the complexity that spills the concept of human rights, on the third, approach the Levinasian thought, especially the categories otherness, responsibility and ethical interpellation, in the fourth part, we reflect on the challenges and possibilities of thinking about teacher education from the ethics perspective and otherness pedagogy and finalizing with some considerations that we have perceived as necessary, recognizing several openings for future research possibilities studies and reflections
The relative efficiency of public schools in developing countries
No full textWith the demand for schooling expected to increase and the tightening of fiscal constraints, changes will be necessary in order to meet ambitious educational targets. Instead of charging fees for public schools, a more cost-effective option is to rely on private schools to handle the growing demand for education. Private school students generally out perform public school students on standardized math and language tests. This finding takes into account that private school students usually come from slightly more advantaged backgrounds than their public school counterparts. In addition, school expenditure data show that unit costs for private schools are dramatically lower than those of public schools. The comparative advantage of private schools has important policy implications for public schools. Some efficiency gains can come from replicating the input mix of private schools. Also effective would be to mimic the organizational incentive structures of private schools.Teaching and Learning,Health Monitoring&Evaluation,Gender and Education,Primary Education,Education Reform and Management
Nouvelles stratégies pour l'identification et l'énumération de macromolécules dans des images de cryo-tomographie électronique 3D
No full textLa cryo-tomographie électronique (cryo-ET) est une technique d'imagerie capable de produire des vues 3D de spécimens biologiques. Cette technologie permet d’imager de larges portions de cellules vitrifiées à une résolution nanométrique. Elle permet de combiner plusieurs échelles de compréhension de la machinerie cellulaire, allant des interactions entre les groupes de protéines à leur structure atomique. La cryo-ET a donc le potentiel d'agir comme un lien entre l'imagerie cellulaire in vivo et les techniques atteignant la résolution atomique. Cependant, ces images sont corrompues par un niveau de bruit élevé et d'artefacts d'imagerie. Leur interprétabilité dépend fortement des méthodes de traitement d'image. Les méthodes computationelles existantes permettent actuellement d'identifier de larges macromolécules telles que les ribosomes, mais il est avéré que ces détections sont incomplètes. De plus, ces méthodes sont limitées lorsque les objets recherchés sont de très petite taille ou présentent une plus grande variabilité structurelle. L'objectif de cette thèse est de proposer de nouvelles méthodes d'analyse d'images, afin de permettre une identification plus robuste des macromolécules d'intérêt. Nous proposons deux méthodes computationelles pour atteindre cet objectif. La première vise à réduire le bruit et les artefacts d'imagerie, et fonctionne en ajoutant et en supprimant de façon itérative un bruit artificiel à l'image. Nous fournissons des preuves mathématiques et expérimentales de ce concept qui permet d'améliorer le signal dans les images de cryo-ET. La deuxième méthode s'appuie sur les progrès récents de l'apprentissage automatique et les méthodes convolutionelles pour améliorer la localisation des macromolécules. La méthode est basée sur un réseau neuronal convolutif et nous montrons comment l'adapter pour obtenir des taux de détection supérieur à l'état de l'art.Cryo electron tomography (cryo-ET) is an imaging technique capable of producing 3D views of biological specimens. This technology enables to capture large field of views of vitrified cells at nanometer resolution. These features allow to combine several scales of understanding of the cellular machinery, from the interactions between groups of proteins to their atomic structure. Cryo-ET therefore has the potential to act as a link between in vivo cell imaging and atomic resolution techniques. However, cryo-ET images suffer from a high amount of noise and imaging artifacts, and the interpretability of these images heavily depends on computational image analysis methods. Existing methods allow to identify large macromolecules such as ribosomes, but there is evidence that the detections are incomplete. In addition, these methods are limited when searched objects are smaller and have more structural variability. The purpose of this thesis is to propose new image analysis methods, in order to enable a more robust identification of macromolecules of interest. We propose two computational methods to achieve this goal. The first aims at reducing the noise and imaging artifacts, and operates by iteratively adding and removing artificial noise to the image. We provide both mathematical and experimental evidence that this concept allows to enhance signal in cryo-ET images. The second method builds on recent advances in machine learning to improve macromolecule localization. The method is based on a convolutional neural network, and we show how it can be adapted to achieve better detection rates than the current state-of- the-art
