Clustering and Token Denoising for Faster and More Robust VLMs

Baptiste Rossigneux, I. Kucher, Vincent Lorrain, Emmanuel Casseau

Recent Visual-Language Models (VLMs) have enhanced the capabilities of pre-trained LLMs by adding vision tokens alongside text, with approaches like LLaVA showing impressive results. However, the computational burden of processing up to 576 or 729 visual tokens makes edge deployment challenging. While …

The article provides data on the effectiveness of the developed model of organizational and methodological support for health and recreational physical activity of cyber athletes, taking into account the peculiarities of their physical activity. The purpose of the study is to assess …

Temporal Dynamics in Visual Data: Analyzing the Impact of Time on Classification Accuracy

Tom Pégeot, Eva Feillet, Adrian Popescu, I. Kucher et autres

Visual datasets are generally constructed from the samples available at the time of their collection and are not further updated. However, these static datasets do not reflect the distribution changes that occur in real data. We analyze how different collection times lead …

A Comprehensive Study of Transfer Learning under Constraints

Tom Pégeot, I. Kucher, Adrian Popescu, Bertrand Delezoide

Pre-training on an upstream task is widely used in deep learning to boost performance of downstream tasks. Recent studies analyzed pre-training with large datasets and large deep neural network architectures. However, pre-training is very useful in practice when downstream tasks have scarce …

Improving Normalizing Flows with the Approximate Mass for Out-of-Distribution Detection

Samy Chali, I. Kucher, Marc Duranton, Jacques‐Olivier Klein

Normalizing flows are generative models that show poor performance on out-of-distribution (OOD) detection tasks with a likelihood-based test. In this study we focus on the "approximate mass" metric. We show that while it improves OOD detection performance, it has limitations under a …
