I am a Third year Ph.D. student in Computer Science at University of Maryland. I am also a part-time researcher at Comcast Applied Artificial Intelligence Research Lab. I work on Machine Learning and Optimization. I am interested in fast, low-complexity solutions to real-world problems.
My research has always been covering a very broad range of Machine Learning topics. However, my recent research efforts have been mostly focused on two major areas: 1) Recommendation Systems, Content Discovery, and Information Retrieval and 2) Machine Learning Algorithm and Applications in Software Engineering.
I also develop and maintain the Project Mangrove website. Feel free to check it out and help us furthur our research goals.

I did my undergraduate studies in Software Engineering at Sharif University of Technology. I also co-founded and managed an educational center for helping high school students prepare for Olympiads while I was doing my undergrad.

I'm open to all sorts of collaboration. Please feel free to get in touch. You can find my email here.

Inverse Reinforcement Learning with Suboptimal Experts

Existing works in Reinforcement Learning field either explicitly assume the expert trajectories are all optimal, or their algorithms tend to work poorly for sub-optimal expert trajectories. We propose a new algorithm which is much more resilient to sub-optimal trajectories.

Variance Reduction for Kacsmarz methods

Kacsmarz methods are very popular optimization methods but they are prone to non existence of optimal solution and noise in the data. My research focused on utilizing Variance Reduction algorithms to make Kacsmarz methods more robust.

Flip-Flop

Flipping is a local and efficient operation to construct the convex hull in an incremental fashion. However, it is known that the traditional flip algorithm is not able to compute the convex hull when applied to a polyhedron in R3. Our novel Flip-Flop algorithm is a variant of the flip algorithm. It overcomes the deficiency of the traditional one to always compute the convex hull of a given star-shaped polyhedron with provable correctness.
