• NeurIPS 2024 (spotlight) •

MultiOOD is the first-of-its-kind benchmark for Multimodal OOD Detection, characterized by diverse dataset sizes and varying modality combinations.

MultiOOD Benchmark

MultiOOD is based on five public action recognition datasets (HMDB51, UCF101, EPIC-Kitchens, HAC, and Kinetics-600).

Dataset Splits

The splits for Multimodal Near-OOD and Far-OOD Benchmarks are provided under HMDB-rgb-flow/splits/ for HMDB51, UCF101, HAC, and Kinetics-600, and under EPIC-rgb-flow/splits/ for EPIC-Kitchens.

Methodology

An overview of the proposed framework for Multimodal OOD Detection. We introduce A2D algorithm to encourage enlarging the prediction discrepancy across modalities. Additionally, we propose a novel outlier synthesis algorithm, NP-Mix, designed to explore broader feature spaces, which complements A2D to strengthen the OOD detection performance.

Code

The code was tested using Python 3.10.4, torch 1.11.0+cu113 and NVIDIA GeForce RTX 3090. More dependencies are in requirement.txt.
