New framework learns kernels by alignment for multiclass Bayes classification

Researchers have developed a new framework for multiclass Bayes classification that learns kernels through alignment, moving beyond the traditional approach of pre-selecting kernels. This method, termed Collaborative Learning and Inference (CLaI), trains an embedding to match a label-derived target kernel. The framework has been extended to incorporate a learned Mahalanobis distance, improving accuracy, convergence speed, and calibration error on datasets like CIFAR-10 and PathMNIST compared to cosine similarity-based variants. The approach unifies representation learning, kernel alignment, and Bayesian classification, showing promise for various classification tasks. AI

IMPACT This framework unifies representation learning, kernel alignment, and Bayesian classification, potentially improving multiclass classification performance.
