基于弱监督学习的去噪受限玻尔兹曼机特征提取算法
Weakly Supervised Learning with Denoising Restricted Boltz mann Machines for Extracting Featu res
摘要
Abstract
Existing feature extraction algorithms are difficult to capture useful information from complex images .A feature extraction approach is proposed based on the weakly supervised learning with denoising restricted Boltzmann machine(RBM).First, a standard RBM is pre-trained in an unsupervised learning way,which provides a hierarchical mode with a visible layer and a hidden layer.Second,for the visible layer,a stochastic binary switch node is employed.And for the hidden layer,it is divided into fore-ground-hidden nodes and background-hidden nodes based on the score of each hidden node’s activation values and times,thus we can achieve a binary mixture denoising RBMs .Finally,the pixel-wise denoising RBMs is trained by using small number label infor-mation and stochastic switch nodes through multiplicative interaction .The experimental results show that significant performance im-provement is achieved with our proposed method .关键词
