New Information Bottleneck Method Separates Representation Learning from Rate Control

Researchers have developed a new approach to the information bottleneck (IB) framework that separates representation learning from rate control. This method, tested on datasets like MNIST and CIFAR-10, demonstrates that the core information-bearing directions of a representation can remain fixed while rate control is adjusted through scalar gains. This separation significantly reduces computational costs, achieving a 7.7x reduction in MACs and a 2x decrease in training time compared to traditional end-to-end Variational Information Bottleneck (VIB) methods, while also yielding higher average accuracy, particularly under strong compression.
