theory retreat

Bio

I am a PhD student at MIT, under the supervision of Konstantinos Daskalakis. I received a Bachelor’s and a Master’s degree from the Technion, Israel, under the supervision of Prof. Yuval Filmus.

Research interests

I am interested in theoretical computer science, especially in learning theory and complexity. My recent works are of the topics of information complexity, Huffman codes, multi armed bandits and streaming algorithms.

Other research work

  • Yuval Dagan and Saar Zehavi. There is no online sparse regressor with sublinear regret. Presents an answer to the main question asked by Dr. Satyen Kale, published in the open problem section of Conference on Learning Theory 2014. We showed that under standard assumptions on hardness of computation, there is no efficient sparse online learning algorithm with sublinear regret. We did not publish our result.  Link
