Final Project / Mathematical Introduction to Machine Learning
A course final project on source-only cosine-to-WSD loss-curve prediction, treating MPL as a frozen baseline and separating transferable LR-drop response from MPL-LD nuisance drift.
Final Project / Selected Topics in Deep Learning Theory
A course final project and reproducible PyTorch harness for grokking on modular arithmetic, polynomial modular operations, S5 group tasks, and K-ary modular summation.
Midterm Project / Mathematical Modeling
A mathematical modeling midterm project on identifying the source of math solutions, using LaTeX structure, proof rhythm, formula density, and adversarial rewriting as modeling signals.
Challenge Work / Lingjun Quant Challenge
A Lingjun Quant Challenge project using causal Transformer modeling on intraday microstructure data, with emphasis on chronological splits, normalization, and leakage-aware validation.
Final Project / Multi-Agent Foundations
A course final project on StrictCoop-Sokoban, intent-grounded communication, and recurrent MAPPO for partially observable cooperative multi-agent reinforcement learning.
TA Project Design / Data Structures and Algorithms B
A Flask-based Avalon agent battle platform from pkulab409/pkudsa.avalon, with Python submissions, referee-controlled phases, automatic matching, an ELO system, and replay logs.
Independent Mini-Game / Chat-Based Business Narrative
An independent mini-game that uses a chat interface to turn unread messages, supplier pressure, public sentiment, and platform risk into narrative state.
