Language-assisted Vision Model Debugger: A Sample-Free Approach to Finding and Fixing Bugs

no code implementations9 Dec 2023 Chaoquan Jiang, Jinqiang Wang, Rui Hu, Jitao Sang

To address this issue, We propose a language-assisted diagnostic method that uses texts instead of images to diagnose bugs in vision models based on multi-modal models (eg CLIP).

Negative Selection by Clustering for Contrastive Learning in Human Activity Recognition

no code implementations23 Mar 2022 Jinqiang Wang, Tao Zhu, Liming Chen, Huansheng Ning, Yaping Wan

Compared with SimCLR, it redefines the negative pairs in the contrastive loss function by using unsupervised clustering methods to generate soft labels that mask other samples of the same cluster to avoid regarding them as negative samples.

Understanding and Testing Generalization of Deep Networks on Out-of-Distribution Data

no code implementations17 Nov 2021 Jitao Sang, Jinqiang Wang, Rui Hu, Chaoquan Jiang

Deep network models perform excellently on In-Distribution (ID) data, but can significantly fail on Out-Of-Distribution (OOD) data.

Sensor Data Augmentation by Resampling for Contrastive Learning in Human Activity Recognition

no code implementations5 Sep 2021 Jinqiang Wang, Tao Zhu, Jingyuan Gan, Liming Chen, Huansheng Ning, Yaping Wan

The experiment results show that the resampling augmentation method outperforms all state-of-the-art methods under a small amount of labeled data, on SimCLRHAR and MoCoHAR, with mean F1-score as the evaluation metric.
