MetaErr: Towards Predicting Error Patterns in Deep Neural Networks

2026-04-25

AI Summary

This work addresses the critical issue of unexpected failures in deployed deep neural networks due to the absence of reliable error warnings, a problem largely overlooked by existing approaches seeking general-purpose error prediction mechanisms. To this end, the authors propose MetaErr, a novel framework that introduces, for the first time, a meta-model fully decoupled from both the architecture and parameters of the base model. Leveraging meta-learning principles, MetaErr learns to classify whether the base model’s prediction on a given sample is erroneous by analyzing its behavioral features, without requiring access to the base model’s internal structure. This design enables broad generalization across diverse tasks. Extensive experiments demonstrate that MetaErr significantly outperforms strong baselines on three visual benchmark datasets and effectively enhances the accuracy of pseudo-label filtering in semi-supervised learning scenarios.

Abstract

Due to the unprecedented success of deep learning, it has become an integral component in several multimedia computing applications in todays world. Unfortunately, deep learning systems are not perfect and can fail, sometimes abruptly, without prior warning or explanation. While reducing the error rate of deep neural networks has been the primary focus of the multimedia community, the problem of predicting when a deep learning system is going to fail has received significantly less research attention. In this paper, we propose a simple yet effective framework, MetaErr, to address this under-explored problem in deep learning research. We train a meta-model whose goal is to predict whether a base deep neural network will succeed or fail in predicting a particular data sample, by observing the base models performance on a given learning task. The meta-model is completely agnostic of the architecture and training parameters of the base model. Such an error prediction system can be immensely useful in a variety of smart multimedia applications. Our empirical studies corroborate the promise and potential of our framework against competing baselines. We further demonstrate the usefulness of our framework to improve the performance of pseudo-labeling-based semi-supervised learning, and show that MetaErr outperforms several strong baselines on three benchmark computer vision datasets.
