I A Projects &  Applications

Deep Learning  

NLP project: "SKIMlLIT"
Developer of a NLP model to classify abstract sentences into the role they play (e.g. objective, methods, results, etc) to enable researchers to skim through the literature (hence SkimLit ) and dive deeper when necessary. Feature engineering is used; hybrid models, different embedding forms(multi data models).  A f1 score of 0.79 was reached in test dataset.

september 2021 - october 2021

Deep Learning 

Computer vision project: "FOOD VISION"
Developer of a model based on convolutional neural networks with Tensorflow that allows identifying between 101 different classes of food dishes, using EffcientNet (transfer-learning) and new mixed precision features of tensorflow. 75,750 images (750 per class) were used for the training set and 25,250 (250 per class) images for the test set, an accuracy of 0.80 was reached  in test dataset .

may 2021 - august 2021

Machine Learning  

End-to-end-bulldozer-price-regression

Developer of a predictive random forest regression model with Scikit-learn and Python to estimate the cost of sales of heavy machinery(bulldozer), based on time series data. Exploratory data analysis ,data cleaning, feature engineering, model selection, evaluation metrics and feature importance. The data is from the Kaggle Bluebook for Bulldozers competition. A r square value of 0.87 was achieved  in test dataset .

march 2021 - april 2021

Machine Learning

 Heart disease detection (binary classification project)

Developer of a logistic regression model with Scikit-learn for binary classification of patients with heart diseases, based on previous medical récords(14 different medical features). EDA, model selection, feature importance, metrics evaluation: ROC curve and AUC score, confusion matrix, accuracy, recall and f1 with cross validation. the model achieved a value of f1 of 0.88  in test dataset .
