New Vendi Score quantifies language model ensemble diversity

By PulseAugur Editorial · [1 sources] ·

A new research paper introduces the Vendi Score, a method for quantifying the semantic diversity of outputs from multiple language models. This score measures the effective number of distinct formulations generated by an ensemble of models, addressing the challenge of assessing diversity when no single correct answer exists. The study also proposes a 'per-model dissent contribution' to identify the most divergent voice within an ensemble, finding that model identity influences dissent but is not fully captured by standard categories.

IMPACT Introduces a novel metric for assessing the diversity and uncertainty of LLM ensembles, aiding in the interpretation of their outputs.

    Sixteen models, fewer than two voices: measuring ensemble dispersion where no answer is uniquely correct

    arXiv:2608.00285v1 Announce Type: new Abstract: Sixteen language models drawn from ten families produced, on average, the semantic diversity of 1.69 distinct formulations of a psychotherapeutic case, against a single-model baseline of 1.43 from one model's own runs. Ensembles pla…
