New method enables multiclass classification from unlabeled data

Researchers have developed a novel method for multiclass classification that can learn from unlabeled data by analyzing the geometry of posterior probabilities. This approach, termed Classification without Labels (CWoLa), extends previous binary classification techniques to scenarios with more than two classes. By observing different mixtures of latent classes, the model can infer the underlying class structure and train a classifier without explicit labels, demonstrating effectiveness on datasets like MNIST and CIFAR-10.
