Sagar Thacker's Projects
Built an RL agent that learns to play Numerical Tic-Tac-Toe with odd numbers. Agent has been trained using Q-Learning. The environment is playing randomly with the agent, i.e. its strategy is to put an even number randomly in an empty cell.
Experimented with different reinforcement learning algorithms to train an agent on Custom Grid World Environment, CartPole-v1, Acrobot-v1, and Atari Breakout.
A Part-Of-Speech Tagger (POS Tagger) is a piece of software that reads text in some language and assigns parts of speech to each word (and other token), such as noun, verb, adjective, etc. Develop a POS tagger using HMM and Viterbi Algorithm. Also, modify the vanilla Viterbi Algorithm to handle the unknown words.
Tool for producing high quality forecasts for time series data that has multiple seasonality with linear or non-linear growth.

End-to-end Machine Learning Project on AWS
The aim of the project was to create an end-to-end web search engine along with an analytics dashboard. The search engine used covid and vaccine twitter tweets for indexing and used the Okapi BM 25 model to retrieve relevant tweets for a given query.
