Tony Jebara works on machine learning and statistical inference. Learning involves fitting models to large-scale data by optimally estimating parameters and structure. Inference involves using these models to predict labels of interest or finding the most likely and marginal configurations of any hidden variables of interest. The models Jebara focuses on are probabilistic graphical models: large networks which describe the conditional independencies between variables in a system.

Research Interests

Machine learning, statistics, optimization, recommendation engines, social networks, graph algorithms.

Jebara has created algorithms that apply graphical models to social networks, recommendation engines, power networks, financial networks, news/social media, mobile communication networks, co-location networks, brain neuron networks, program execution graphs, and more. Real-world applications include modeling social network data to enable friend recommendation, modeling mobile phone data-sets (such as call-detail records) to find users with similar behavior, and personalizing recommendation systems to suggest items of interest to users.

Jebara received a Bachelor’s degree in honors Electrical Engineering from McGill University in 1996, an MS degree in Media Arts & Sciences from MIT in 1998 and a PhD degree in Media Arts & Sciences from MIT in 2002. In 2004, Jebara was the recipient of the Career award from the National Science Foundation. His work was recognized with a best paper award at the 26th International Conference on Machine Learning, a best student paper award at the 20th International Conference on Machine Learning as well as an outstanding contribution award from the Pattern Recognition Society in 2001. Jebara was the Program Chair of the 2014 ICML conference and is the General Chair of the 2017 ICML conference. Esquire magazine named him one of their Best and Brightest of 2008.
