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 WebWhile Greedy InfoMax separately learns each block with a local objective, we found that it consistently hurts readout accuracy in state-of-the-art unsupervised contrastive learning algorithms, possibly due to the greedy objective as well as gradient isolation.
