A Coin Flip Per Token: Bernoulli Sparse Steering of Large Language Models

Stochastic Token Steering (STS), which gates each token independently with probability $p$, and Stochastic Block Steering (SBS), which gates a leading window once per sequence are introduced; neither requires a reward model or learned gating policy.

A Hitchhiker’s Journey through Machine Learning for Structural Biology of Antibodies

This thesis examines the integration of machine learning into computational structural biology, with an emphasis on modelling and predicting antibody–antigen interactions. Such interactions are fundamental to numerous biological processes and are central to therapeutic antibody design. Despite recent advances in AI-bas...
