SKILLS

PROJECTS

Forecasted Ethereum Prices Using Machine Learning

Analyzed 6 years of historical Ethereum price data from Bitstamp. Developed machine learning pipleines evaluating 5 models including XGBoost, achieving a 99.3% predictive power on holdout data.

Go Bot

Engineered a Go-playing bot utilizing Convolutional Neural Networks (CNN) to understand intricate dynamics in the game of go, showing an accurate reaching 15% (baseline: .028%).

Skills: Python, CNN, Monte Carlo Tree Search, Keras

Examining Water Usage

Using K-means clustering to group counties based on water use patterns showed big differences in how much water is used for things like watering crops, supplying homes, and mining across counties. The results indicate specific chances for counties to work together to use water better in raising animals, mining, and fish farming as well as hints that people with higher incomes may use more water.

Skills: Python, Pandas, K-means clustering, DBSCAN, Git

Subreddit NLP
