Projects
PPO Reinforcement Learning Model for Retro Video Games
Built a functioning reinforcement learning model for the retro video game Super Street Fighter II implementing stable-baselines 3, which is based on OpenAI’s Baselines.

Utilized Optuna to automate hyperparameter search and optimize model hyperparameters.
Integrated TensorFlow to monitor agent performance and hyperparameters tuning.
Rudimentary Photo Recognition of whiteboard writing using Linear Algebra and Python
Implemented a non-neural network approach for distinguishing Pi and Tau symbols written on a whiteboard by converting submitted images into a 3x3 matrix of 1s and 0s and applying matrix math to them.
Leveraged properties of invertible matrices from linear algebra, and was able to convert a matrix into a vector and multiply it by another matrix to determine if the letter written was Pi (ⲡ), Tao (τ), or neither in O(1) efficiency.
