CAPO

Compute-Aware Automated Protein-Model Optimization

An agentic system for end-to-end protein-model optimization, evaluated through three protein-engineering tasks and ablation studies. The project explores how to make model optimization effective under compute constraints.

Small But Mighty: Achieving High Accuracy with Small Language Models on scientific MCQ answering

In this 10-week project, our group of three aimed to improve a small language model on scientific question answering using EPFL exam questions. We fine-tuned and quantized the model for single-GPU training, applied Direct Preference Optimization (DPO), and expanded its knowledge with Retrieval-Augmented Generation (RAG).
