Anyone AI | Aug 2022 - Feb 2023

Machine Learning Engineer

Worked with industry experts developing high-quality data science and machine learning projects for the industry. ● Product detection for in-store inventory management with YoloV5: Applied computer vision techniques to detect products in images of supermarket shelves. Built an API service, backed by a machine learning model for object detection (YoloV5) that returned the bounding boxes with the location of missing products, achieving a Mean Average Precision of 82%, a recall of 78%, and a precision of 87%. ● Natural Language Processing for Sentiment Analysis: trained a neural network for the classification of 50K real-life movie reviews based on users' sentiments using word2vec GenSim with an AUC score of around 87% and F1-Score of 78%. ● Neural Network for Vehicle Classification: training and fine-tuning of a CNN (Resnet50 architecture) on AWS for the classification of 16000 different car images with an overall accuracy of 75% for 196 different vehicle classes. The model was tuned using different techniques: hyperparameter optimization (a combination of learning rate, dropout, and regularization), re-processing steps such as image cropping and data augmentation (image flipping, rotation and zoom). ● Credit Risk Analysis with binary classification models: Developed feature engineering, data preprocessing, built a machine learning pipeline and trained high-performance binary classifiers such as Logistic Regressor, Tree-based and Gradient Boosting Machine models, for the problem of classification in a home credit risk analysis real-life application, with an overall ROC-AUC score of 76%
