Researchers have developed a new method called geometric consistency for selecting checkpoints in audio active learning. This label-free validation technique aims to reduce the cost of annotation by avoiding the need for a separate validation set. The method models the geometry of unlabeled data using classifiers trained on a labeled set and scores checkpoints based on their agreement with pseudo-labels and cross-entropy on the labeled set. This approach has shown competitive performance compared to methods that use extra labels or out-of-budget validation sets. AI
