Igeood: An Information Geometry Approach to Out-of-Distribution Detection

ICLR 2022poster

Reliable out-of-distribution (OOD) detection is fundamental to implementing safer modern machine learning (ML) systems. In this paper, we introduce Igeood, an effective method for detecting OOD samples. Igeood applies to any pre-trained neural network, works under various degrees of access to the M…

Learning-Based Lossless Compression of 3D Point Cloud Geometry

ICASSP 2021accepted

This paper presents a learning-based, lossless compression method for static point cloud geometry, based on context-adaptive arithmetic coding. Unlike most existing methods working in the octree domain, our encoder operates in a hybrid mode, mixing octree and voxel-based coding. We adaptively partit…

Learning Semi-Supervised Anonymized Representations by Mutual Information

ICASSP 2020accepted

This paper addresses the problem of removing from a set of data (here images) a given private information, while still allowing other utilities on the processed data. This is obtained by training concurrently a GAN-like discriminator and an autoencoder. The optimization of the resulting structure in…

Transform Coefficient Coding for Screen Content in Versatile Video Coding (VVC)

ICASSP 2019accepted

A transform coefficient coding scheme is proposed for 4 × 4 blocks in Versatile Video Coding (VVC), targeting screen content applications. The proposed algorithm, called Unary Bitplane Coding (UBC), uses unary codes of the coefficient amplitudes and represents each block by their bitplanes. This rep…
