    During the COVID-19 pandemic, airports faced a significant drop in passenger numbers, impacting the vital hub of the aircraft transportation industry. This study aimed to evaluate whether Long Short-Term Memory Network (LSTM) and Convolutional Neural Network - Long Short-Term Memory Network (CNN-LSTM) offer more accurate predictions for airport traffic during the COVID-19 pandemic from March to December 2020. The studies involved data filtering, applying min-max scaling, and dividing the dataset into 80% training and 20% testing sets. Parameter adjustment was performed with different optimizers such as RMSProp, Stochastic Gradient Descent (SGD), Adam, Nadam, and Adamax. Performance evaluation uses metrics that include Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), Root Mean Square Error (RMSE), and R-squared (R2). The best LSTM model achieved an impressive MAPE score of 0.0932, while the CNN-LSTM model had a slightly higher score of 0.0960. In particular, the inclusion of a balanced data set representing a percentage of the base period for each airport had a significant impact on improving prediction accuracy. This research contributes to providing stakeholders with valuable insights into the effectiveness of predicting airport traffic patterns during these unprecedented times

    The COVID-19 pandemic has posed significant challenges to airport traffic management, necessitating accurate predictive models. This research evaluates the effectiveness of various optimizers in enhancing airport traffic prediction using Deep Learning models, specifically Gated Recurrent Units (GRU) and Convolutional Neural Network-Gated Recurrent Units (CNN-GRU). We compare the performance of optimizers including RMSprop, Adam, Nadam, AdamW, Adamax, and Lion, and analyze the impact of their parameter tuning on model accuracy. Time series data from airports in the United States, Canada, Chile, and Australia were used, with preprocessing steps like filtering, cleaning, and applying a MinMax Scaler. The data was split into 80% for training and 20% for testing. Our findings reveal that the Adam optimizer paired with the GRU model achieved the lowest Mean Absolute Error (MAE) and Mean Absolute Percentage Error (MAPE) in the USA. The study underscores the importance of selecting and tuning optimizers, with ReduceLROnPlateau used to adjust the learning rate dynamically, preventing overfitting and improving model convergence. However, limitations include dataset imbalance and region-specific results, which may affect the generalizability of the findings. Future research should address these limitations by developing balanced datasets and exploring optimizer performance across a broader range of regions and conditions. This study lays the groundwork for further investigating sustainable and accurate airport traffic prediction models

    Oikeusturvan toteutuminen poikkeusolojen aikana

    Get PDF
    Suomen perustuslakiin kirjatuista perusoikeuksista yksi on oikeusturva, joka turvaa yksilölle oikeuden saada asiansa käsitellyksi sekä oikeuden saada perusteltu päätös (21 §). Oikeus-turva takaa yksilölle oikeudet omiin oikeuksiinsa ja täten myös turvaa muiden perusoi-keuksien toteutumista. Oikeusturva on myös merkittävä osa oikeusvaltioperiaatetta ja sen toteutumista. Perustuslaissa on kuitenkin annettu mahdollisuus tehdä poikkeuksia perus-oikeuksiin, mikäli erityinen tilanne tämän vaatii (23 §). Poikkeusolot on määritelty val-miuslaissa (3 §). Poikkeusoloja ovat sellaiset kriisitilanteet, jossa yhteiskunnan normaali-toiminta on merkittävästi uhattuna. Tässä lainopillisessa tutkielmassa tarkastellaan sitä, miten oikeusturvaa toteutetaan myös poikkeusolojen aikana. Tutkielma keskittyy tarkastelemaan oikeusturvaa käsitteenä ja pe-rusoikeutena sekä oikeusvaltion elementtinä. Lisäksi tarkastellaan poikkeusolojen oikeu-dellista sääntelyä sekä oikeusturvan toteutumisen turvaamista poikkeusolojen aikana. Tut-kielman keskiössä on kansallinen lainsäädäntö, jota täydennetään EU-oikeudella. Tutkimuksesta käy ilmi, että oikeusturvaa pidetään yhtenä tärkeimpänä oikeutena ja sen turvaaminen on otettu julkisessa toiminnassa huomioon. Oikeusvaltioperiaate sekä hallin-non oikeusperiaatteet suojaavat oikeusturvan toteutumista. Perustuslakivaliokunta, ylim-mät laillisuusvalvojat sekä tuomioistuimet toteuttavat oikeusturvaa omilla osa-alueillaan. Tutkimuksessa kävi ilmi, että poikkeusoloissakin lähtökohtana on se, ettei ylimääräisiä ra-joituksia perusoikeuksiin tehtäisi eikä laajempia toimivaltuuksia otettaisi käyttöön, jos tilanne on mahdollista hoitaa normaalein toimivaltuuksin. Tätä tulosta puoltavat säädökset löytyvät valmiuslaista ja puolustustilalaista. Tutkielmassa tultiin myös siihen tulokseen, että ennakointi ja hyvä lainsäädännön valmistelu mahdollisia kriisitilanteita varten turvaa-vat perusoikeuksien paremman toteutumisen. Tutkimuksessa tultiin myös tulokseen, että valmiuslain jo itsessään on tarkoitus ylläpitää oikeusjärjestystä ja perusoikeuksia. Oikeus-turvan toteutuminen poikkeusoloissa on kiinni varautumisesta, oikeusvaltioperiaatteen noudattamisesta ja turvaamisesta

    Anemia is a prevalent hematological condition marked by decreased hemoglobin concentration in the blood, which can lead to serious health complications if undetected. Although machine learning has shown potential in supporting early diagnosis, its effectiveness is often hindered by irrelevant or excessive features. This study investigates the impact of ANOVA and Chi-Square feature selection methods in improving the effectiveness of three distinct machine learning models algorithms, Naive Bayes, K-Nearest Neighbor (KNN), and Support Vector Machine (SVM) for anemia classification. Using a Kaggle dataset consisting of 15,300 instances and 25 features, the evaluation of each model was conducted with reference to its accuracy, precision, recall, and F1-score, both before and after applying feature selection. Experimental results show a substantial improvement in classification performance after feature selection, with the SVM + ANOVA combination achieving the highest accuracy of 94.61%. In contrast, models without feature selection performed below 90%, highlighting the need for appropriate feature reduction techniques. This study contributes a comparative analysis framework for medical data classification, emphasizing the role of statistical feature selection in optimizing model accuracy. Its novelty lies in demonstrating consistent performance improvement across algorithms using real-world anemia data and providing evidence that ANOVA and Chi-Square can significantly enhance model generalization in medical diagnostic contexts
