This exercise set is built around linear probing, one of the most important tools in mechanistic interpretability for understanding what information language models represent internally. We'll look at three papers: The core idea: extract internal activations from a model, then train a simple classifier on them. If a linear probe can accurately classify some property from the activations, that property is linearly represented in the model's internal state. From the Geometry of Truth paper: "We identify a linear representation of truth that generalizes across several structurally and topically diverse datas
