Bio

I am a Computer Science Master’s student at the Technion, Israel, studying under the supervision of Prof. Yuval Filmus. I obtained my Bachelor’s degree in Computer Science from the Technion.

Research interests

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