Data-Centric Explainable Machine Learning

摘要

The quality of training data is crucial to the success of supervised and semi-supervised learning. Errors in data have long been known to limit the performance of machine learning models. This talk presents the motivation and major challenges of data quality diagnosis and improvement. With that perspective, I will then discuss some of our explainable machine learning efforts from the data perspective: 1) analyzing and correcting poor annotation quality, 2) resolving the poor coverage of the training data caused by dataset bias, 3) enriching training data by fusing multimodal information.
