What Are Common Ambiguities in Data Labeling?

TL;DR

Common ambiguities in data labeling include challenges in speech recognition where unclear audio complicates transcription, and in user ID merging, where determining if two data records belong to the same person can be difficult. Ensuring consistent labeling practices is crucial to improve the performance of learning algorithms in situations with ambiguous data.
