About Al Amin Hosain

Machine Learning (ML) enthusiast with 8+ years of research and development (industry & academic) experience in building, training and evaluating ML models. Experienced in building transformer-based entity matching models to deliver business insights, with end-to-end expertise in training, validating, and deploying machine learning solutions. Developed scalable, OOP-designed ML repositories adaptable to diverse clients and data sources. During my PHD, I proposed and developed ML models that attempt to understand activities/gestures from videos. I have developed different ML models for spatio-temporal modeling in video data. For spatial component, I have used Convolutional Neural Network (CNN) based approaches. To model the temporal aspects in data I have used Recurrent Neural Network (RNN) variants. I proposed and developed a 3d CNN based approach to model videos in the context of American Sign Language (ASL) sign gesture recognition. Body key-points data (pose) were used to guide the important feature extraction from the feature maps of 3d CNN. • GENERAL PROGRAMMING: Python, C++, C, Java, Object Oriented Design, Problem Solving (Algorithm & Data Structures). • MACHINE LEARNING THEORY: ML foundation, Linear Models (SVM, Logistic Regression, Linear Regression), Decision Tree, Bagging, Boosting, Naïve Bayes, k-NN, k-Means, Parameter Estimation ( MLE, MAP, Expectation Maximization, GMM). • DEEP LEARNING: Transformer Models, Nvidia TensorRT, Convolutional Neural Network (CNN), 3d CNN, Graph Convolutional Network (GCN), Recurrent Neural Network (RNN), LSTM, GRU, Transformer Networks, Attention Models, Multi-modal Fusion, Weakly/Semi Supervised Learning, Autoencoder. • ML TOOLS: PyTorch, TensorFlow, Keras, scikit-learn, OpenCV, Pandas, Spark, Hadoop. • OTHERS: Hypothesis Testing, A/B Testing
