Linear probes trained on LLM hidden states are increasingly used for malicious intent detection in agentic systems, often achieving near-perfect The concept of the probe makes sense only when we assume that it is the optimal possible linear classifier (or very close to that in practice). All rights reserved. Deep networks are usually judged by their final answer. linear probe. Subscribe. The worst-case performance of a linear probing algorithm is studied under assumption that each of m locations can contain at most one record. With the growing presence of AI in society, it becomes increasingly important to develop methods that can explain and interpret the decisions made by these a linear probe can classify true versus false statements from internal activations,; a steering vector can move the model toward one side of Linear probing scans forward for the next open slot.
