无监督学习算法unsupervised learning algorithm估计概率分布\(p(\mathbf x)\)。显式的如密度估计和聚类,隐式的如合成或去噪。 有监督学习算法supervised learning algorithm估计\(p(\mathbf {y|x})\),可以理解为映射。 训练集带有标记label或目标target。 实际上这两个分类的交集是存在的。由于chain rule: \[p(...
科学网机器学习前沿热点–deeplearning.pdf,科学网机器学习前沿热点– deep learning 引言:神经网络 (Neural Network )与支持向量机 (Support Vector Machines ,SVM )是统计学习的代表方法。可以认为 神经网络与支持向量机都源自于感知机( Perceptron)。感知 机是 1
• A core component of the DBN is a greedy, layer-by-layer learning algorithm which optimizes DBN weights at time complexity linear to the size and depth of the networks. • Initializing the weights of an MLP with a correspondingly configured DBN often produces much better results than ...
