New framework analyzes transformer internal state dynamics

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called Markovian Circuit Tracing (MCT) to analyze the internal state dynamics of transformer models. This method uses synthetic Hidden Markov Model (HMM) tasks to test if transformer activations exhibit coarse state-transition structures. The findings indicate that transformers can learn near-Bayes next-token predictors and that residual activations contain partial Bayesian belief information, with state patching significantly improving accuracy.

    Markovian Circuit Tracing for Transformer State Dynamic

    Many sequence computations are easier to study as movement through internal states than as isolated local circuits. We introduce Markovian Circuit Tracing (MCT), a diagnostic pipeline for testing whether transformer activations contain coarse state-transition structure. The bench…
