Projects
Sometimes, I build stuff:
- Word Game Bench – evaluating language models on puzzles. OpenRouter sponsored the project, and Mark Chen (SVP of Research at OpenAI) expressed interest in the results.
- Answers to Chip Huyen's ML Interview Questions – a booklet answering interview questions covering Math, Computer Science, ML workflows and algorithms.
- Laser Hockey – my winning entry to a Reinforcement Learning tournament with 70 participants, organized by the Max Planck Institute for Intelligent Systems.
- Morty – An "agent" based on IBM Watson intents and an LSTM pre-trained on Reddit data I built all the way back in 2018!
Blog
Other times, I write stuff:
- Speeding up decoder inference with a Key-Value (KV) cache
- Boosting transformer efficiency with Grouped-Query Attention (GQA)
- Stabilizing training and improving model convergence with RMSNorm
- Activating neurons with Gated Linear Units (GLU) and Friends
- Encoding positional information with Rotary Position Embeddings (RoPE)
- Decoupling weight decay with AdamW
- Overcoming catastrophic forgetting with Elastic Weight Consolidation (EWC)
Biomarkers
With the goal of keeping myself accountable and maintaining good physical health, I'll continually open-source my biomarkers.
