Projects

• Self Evaluation: Robot evauating its confidence in performing complex manipulation tasks [code] Paper: [arXiv,2024] Self-evaluation is a probabilistic algorithm that enables the Robot to evaluate whether, for a particular task to be performed in a given workspace, it has a sufficient number of demonstrations in order to generate feasible manipulation plans while satisfying the task-related motion constraints. The underlying method relies upon an \(\epsilon\)-optimal arm identification in a Multi-armed Bandit setup using \((\epsilon,\delta)\)-PAC (Probably Approximately Correct ) learning.
• Ultimate Tic-Tac-Toe: 9 Synchronized Tic-Tac-Toe Boards [code] An AI agent inspired by the AlphaZero algorithm and trained using deep Reinforcement Learning techniques such as Monte-Carlo Tree Search and Deep Q-Network , for playing the non-trivial board game of Ultimate Tic-Tac-Toe, where 9 small Tic-Tac-Toe boards work in tandem, giving rise to a gameplay more complex than Othello . The agent — trained using self-play against itself for 7 days on a low-end GPU — defeated an average human player with Elo rating of 1400+ in chess 8 out of 10 times.
• UnreLyzer: A static interval analyzer for C like unreliable programs [code] Paper: [arXiv,2016] Unrelyzer is a static analysis tool that analyzes a program defined by a subset of C (Mini-C) grammar with an addendum where each arithmetic, boolean and memory (Read/Write) operation in the program is probabilistic/unreliable in nature. This tool statically analyzes the program using Abstract Interpretation in the interval domain and determines the interval of values with a certain confidence for each program variable at each program point. This tool was built as part of my Master’s thesis.
