WebGreedy InfoMax works! Not only does it achieve a competitive performance to the other tested methods, we can even see that each Greedy InfoMax module improves upon its predecessors. This shows us that the … WebGreedy InfoMax (GIM), the encoder network is split into several, gradient-isolated modules and the loss (CPC or Hinge) is applied separately to each module. Gradient back-propagation still occurs within modules (red, dashed arrows) but is blocked between modules. In CLAPP, every module contains only a single trainable layer of the L-layer …
