Using complementary priors, we derive a fast, greedy algorithm that can learn deep, directed belief networks one layer at a time, provided the top two layers form an undirected associative memory. The fast, greedy algorithm is used to initialize a slower learning procedure that fine-tunes the ...
推出了一个greedy algorithm,可以一次只学习belief net的一层,并利用wake-sleep算法的对比版本——up-down算法对网络进行微调。最后,实现了一个只有三层的神经网络对mnist数据集的识别。 作者想解决什么问题?explaining away的存在使得具有多层的网络的训练难度加大,作者尝试解决多层网络训练困难的问题 作者通过什么理论/...
当然也有别的做法可以保证算法运行过程中C3和C4条件总是成立,但取最小距离标号的超额流超过Δ/2是一种简单而高效的做法。 在C3和C4条件成立的情况下,推流操作可以被视为一种restrained greedy approach(受限制的贪心方法)。C3保证了从i到j的推流足够大而有效,C4保证了每次迭代不会有超额流超过Δ。特别地,节点i...

Here we consider a scheme based on a standard “greedy” optimization algorithm, which appears to perform well. Our algorithm falls in the general category of agglomerative hierarchical clustering methods [15, 16]. Starting with a state in which each vertex is the sole member of one of n ...
