摘要： Curator: Max Welling Dr. Max Welling, School of Information and Computer Science, University of California, Irvine, CA A Product of Experts model (PoE) (Hinton 2002) combines a number of individual component models (the experts) by taking their product and normalizing the result. Each expert is defined as a possibly unnormalized probabilistic model f(x) over its input space. 阅读全文

摘要： A Boltzmann machine is a network of symmetrically connected, neuron-like units that make stochastic decisions about whether to be on or off. Boltzmann machines have a simple learning algorithm (Hinton & Sejnowski, 1983) that allows them to discover interesting features that represent complex regularities in the training data. The learning algorithm is very slow in networks with many layers of feature detectors, but it is fast in "restricted Boltzmann machines" that have a single layer of feature 阅读全文

摘要： Deep Belief Network 为了更好的在下次讨论班讲述 DBN，特开此帖。主要是 介绍 DBN 的相关知识，做一份逻辑上完整的东西。参考 Hinton 的东西来讲吧： 阅读全文
