Greedy infomax
WebJan 25, 2024 · Greedy InfoMax Intuition. The theory is that the brain learns to process its perceptions by maximally preserving the information of the input activities in each layer. Web3.2 Greedy InfoMax As unsupervised learning has achieved tremendous progress, it is natural to ask whether we can achieve the same from a local learning algorithm. Greedy InfoMax (GIM) [39] proposed to learn representation locally in each stage of the network, shown in the middle part of Fig. 1. It divides

WebComputer Science. ECCV. 2024. TLDR. An information-theoretic objective, InfoMax-Bottleneck (IMB), is introduced, to carry out KF by optimizing the mutual information between the learned representations and input, and yields gratifying performances on not only the dedicated tasks but also disentanglement. 13. hill country humane society buchananWe simply divide existing architectures into gradient-isolated modules and optimize the mutual information between cross-patch intermediate representations. What we found exciting is that despite each module being trained greedily, it improves upon the representation of the previous module.
