New algorithm efficiently learns noisy multiclass linear classifiers

Researchers have developed a new algorithm for efficiently learning multiclass linear classifiers, even when the data is corrupted by a constant rate of noise. This algorithm requires a sample complexity of O(k^2 * (d log d + log k)) and utilizes a combination of a cluster-based pruning scheme and multiclass hinge loss minimization. The findings are significant as they offer a stronger result than previous work, even in the binary classification case. AI
