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. 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 …
