Exploring Precision and Recall to assess the quality and diversity of LLMs

no code implementations16 Feb 2024 Florian Le Bronnec, Alexandre Verine, Benjamin Negrevergne, Yann Chevaleyre, Alexandre Allauzen

We introduce a novel evaluation framework for Large Language Models (LLMs) such as \textsc{Llama-2} and \textsc{Mistral}, focusing on importing Precision and Recall metrics from image generation to text generation.

Optimal Budgeted Rejection Sampling for Generative Models

no code implementations1 Nov 2023 Alexandre Verine, Muni Sreenivas Pydi, Benjamin Negrevergne, Yann Chevaleyre

Rejection sampling methods have recently been proposed to improve the performance of discriminator-based generative models.

Training Normalizing Flows with the Precision-Recall Divergence

no code implementations1 Feb 2023 Alexandre Verine, Benjamin Negrevergne, Muni Sreenivas Pydi, Yann Chevaleyre

Generative models can have distinct mode of failures like mode dropping and low quality samples, which cannot be captured by a single scalar metric.

On the expressivity of bi-Lipschitz normalizing flows

no code implementations ICML Workshop INNF 2021 Alexandre Verine, Benjamin Negrevergne, Fabrice Rossi, Yann Chevaleyre

An invertible function is bi-Lipschitz if both the function and its inverse have bounded Lipschitz constants.
