Small Language Models are Good Too: An Empirical Study of Zero-Shot Classification

no code implementations17 Apr 2024 Pierre Lepagnol, Thomas Gerald, Sahar Ghannay, Christophe Servan, Sophie Rosset

This study is part of the debate on the efficiency of large versus small language models for text classification by prompting. We assess the performance of small language models in zero-shot text classification, challenging the prevailing dominance of large models. Across 15 datasets, our investigation benchmarks language models from 77M to 40B parameters using different architectures and scoring functions.

CoSPLADE: Contextualizing SPLADE for Conversational Information Retrieval

no code implementations11 Jan 2023 Nam Le Hai, Thomas Gerald, Thibault Formal, Jian-Yun Nie, Benjamin Piwowarski, Laure Soulier

Conversational search is a difficult task as it aims at retrieving documents based not only on the current user query but also on the full conversation history.

From Node Embedding To Community Embedding : A Hyperbolic Approach

2 code implementations2 Jul 2019 Thomas Gerald, Hadi Zaatiti, Hatem Hajri, Nicolas Baskiotis, Olivier Schwander

Considering the success of hyperbolic representations of graph-structured data in last years, an ongoing challenge is to set up a hyperbolic approach for the community detection problem.

Binary Stochastic Representations for Large Multi-class Classification

no code implementations24 Jun 2019 Thomas Gerald, Aurélia Léon, Nicolas Baskiotis, Ludovic Denoyer

Different models based on the notion of binary codes have been proposed to overcome this limitation, achieving in a sublinear inference complexity.
