Avradeep Bhowmik

I am a Research Scientist at Criteo AI Labs since March 2019, with a focus on Machine Learning, Data Science and related areas. Currently, I am collaborating with a team on using RNN's (LSTM's, GRU, etc) and language models (ELMo, BERT, etc.) for automated taxonomic product categorisation. Prior to this, I worked on the development and testing of gradient-boosted tree-based models for bid-optimisation in online advertising.

Before joining Criteo, I obtained a PhD degree from The University of Texas at Austin where my thesis focused on privacy-preserving learning from aggregated/obfuscated data. I was supervised by Prof. Joydeep Ghosh, and was affiliated with the Intelligent Data Exploration and Analysis Laboratory (IDEA Lab) and the Wireless Networking and Communications Group (WNCG) between 2013--2018.

I received my Master of Science (M.S.) degree from the Department of Electrical and Computer Engineering at UT Austin in 2016. Prior to graduate school, I received a Bachelor of Technology (B.Tech.) in Electrical Engineering from the Indian Institute of Technology, Bombay (IIT Bombay) in 2013. At IIT Bombay, I worked on my undergraduate thesis under the supervision of Prof. Vivek Borkar.




Interests

I am broadly interested in machine learning, data mining, statistical inference and related fields. In my education and my professional life, I have had a specific focus on machine learning and data mining in two domains-- online advertising and healthcare-- that included techniques like gradient boosted decision trees for bid-optimisation, recommendation systems, data reconstruction algorithms, ranking and rank aggregation, and learning with obfuscated data. In parallel, I have worked on language models using state-of-the-art deep neural networks like RNN's--GRU's and LSTM's-- and Transformers (including a hobby project training a Shakespeare chatbot/text generator). In the past I have also worked on applications involving sparse modelling, image processing, language models, hierarchical learning and geometric maps for recommender systems, and submodular optimisation techniques applied to problems in operations research.
