Reinforcement learning (RL) is a way of training an agent to make sequences of decisions by finding the optimal action-taking policy through trial and error interactions with the environment. It is a powerful tool for solving complex problems in robotics, finance, and gaming. To broaden my knowledge in ML, I worked on a few small projects to learn fundamental deep RL algorithms such as (Double) DQN, REINFORCE, DDPG, and PPO. Please see this project if you are interested in NEAT and Pong instead.

NEAT, or NeuroEvolution of Augmenting Topologies, is a genetic algorithm for evolving neural networks. Hayson and I used the neat-python library to train a neural network to play Pong as an optional course project to develop an AI that compete in Pong tournament. The agent maximizes the reward by learning to hit the ball back to the opponent.

How can we make research more accessible, insightful, and engaging for researchers and students? Eddy, Chi, Jay, and I came up with an innovative web application that leverages cutting-edge AI to visualize connections between papers in a force-directed graph.

Using OpenCV, I made my own script to track the motion of a pendulum in for my PHY180 (Mechanics) lab. The script detects the pendulum bob and track its motion in real-time for a directory of videos (samples taken) using cv2. The module supports:

1. Generating plots for amplitude vs time, period vs time, period vs length, etc.

2. Performing curve fitting using scipy with uncertainties and residuals.

3. Calculating quantities such as period and Q-factor.

Most programmers were introduced to coding through Scratch, a block-based programming language that simplifies the process of buliding games, animations, and stories. Why not make machine learning as easy as Scratch, or even better – directly with the framework that made Scratch? (IgnitionHacks)

Sleep deprivation is a widespread issue, expected to worsen as distractions increase. Despite understanding sleep’s benefits, many find it challenging to maintain a healthy night routine. This is especially prominant for students who later face difficulties in focusing and retaining information.

Inspired by the engaging features of Duolingo, WeDream motivates users to stay committed to improving their sleep habits. We are dedicated to empowering individuals who actively seek to improve their daily lives and become the best versions of themselves.
