WebJan 27, 2024 · As more of society begins to see AI for what it really is and considers these ramifications the community will demand new methods. One approach that has recently surfaced is modifying training methods to begin to move from the resource intensive back propagation methods. One example of this is Greedy InfoMax optimization(GIM). This … 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. order flowers online new orleans
