Deep Semi-supervised Anomaly Detection Using VQ-VAE

2023

Anomaly detection is a fundamental and challenging task in computer vision, which determines whether an image contains anomaly or not. Prior works using autoencoders for anomaly detection are based on pixel-wise learning in the continuous …

Learning in Order! A Sequential Strategy to Learn Invariant Features for Multimodal Sentiment Analysis

2024 · arXiv (Cornell University)

This work proposes a novel and simple sequential learning strategy to train models on videos and texts for multimodal sentiment analysis. To estimate sentiment polarities on unseen out-of-distribution data, we introduce a multimodal model that …
