Greedy infomax

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 … Webof useful information. Thus a greedy infomax controller would prescribe to never vocalize, since it results in an immediate reduction of useful information. However, in the long run vocalizations are important to gather information as to whether a responsive human is present. Thus learning to vocalize as a way to gather information requires ...

WebJul 10, 2024 · In this work, we propose a universal unsupervised learning approach to extract useful representations from high-dimensional data, which we call Contrastive Predictive Coding. The key insight of our model is to learn such representations by predicting the future in latent space by using powerful autoregressive models. WebWhile Greedy InfoMax [39] separately learns each block with a local objective, we found that it consistently hurts readout accuracy in state-of-the-art unsupervised contrastive … WebJan 22, 2024 · Results: The researchers pitted Greedy InfoMax against contrastive predictive coding. In image classification, GIM beat CPC by 1.4 percent, achieving 81.9 percent accuracy. In a voice identification task, GIM underperformed CPC by 0.2 percent, scoring 99.4 percent accuracy.
