Projects
YahtzeeRL
Yahtzee agent built with JAX/Flax/RLax, trained through self-play with stochastic MuZero-style MCTS and explicit chance nodes for dice rolls.
81.1% win rate vs heuristic baseline over 512 games
Solar Irradiance Forecasting
Solar irradiance forecasting as a multi-horizon task, comparing GRU, LSTM, seasonal naive, and persistence baselines.
GRU reduced RMSE by ~34% at 4h and ~21% at 24h vs strongest naive baseline
Thesis
Kernel Methods for Regression
Kernel methods for regression problems by implicitly mapping input variables into high-dimensional feature spaces. Comparison of standard ridge regression and kernel ridge regression with algebraic equivalence proof.
