Ethan Fang
Based out of the Bay Area. I spend most of my time in math modeling, AI research, and engineering.
I graduated from Case Western Reserve University in May of 2026 with a BS/MS in computer science. During my time there, I pursued many interests such as: starting the quant finance club, growing club tennis, and doing lots and lots of research.
I enjoy building cool and useful things. This includes a startup I cofounded, Vantura, and a few sites such as iLiterate.
Currently, I am a quantitative analyst at KeyBank where I model expected loss for the bank's portfolio. I continue to stay involved in AI research.

Perpetual Text Generation
Research on extending LLM generation past the natural stopping point. Introduces a method that detects emergent EOS tokens, backsteps, and applies dynamic temperature adjustment — doubled for exploration, then annealed back to baseline. Pushes Llama2-7B-chat ~1,000 additional coherent tokens past where it would otherwise halt.

Q-Learned CNN Branch Selection
Reinforcement-learning agent that dynamically selects convolutional branches at inference time, trading FLOPs for accuracy on a per-sample basis. Trained with Q-learning over a branching CNN backbone.
