surprisal is Not a Theory
Read the original on arXiv Computation and Language →The article argues that Surprisal Theory, often presented as a computational-level explanation, is not a theory in its own right. It contends that using large language model (LLM) surprisals without considering the underlying representational and algorithmic choices obscures the theory’s commitments. The authors demonstrate through three analyses that algorithm and architecture significantly influence language model probabilities, urging researchers to reassess treating LLM surprisals as interchangeable.
