Restricted Boltzmann machines (RBMs) are widely applied to solve many machine learning problems. Usually, the cost function of RBM is log-likelihood function of marginal distribution of input data, and the training method involves maximizing the cost function. Distribution of the trained RBM is identical to that of input data. But the reconstruction error always exists even the distributions are almost identical. In this paper, a method to train RBM by adding reconstruction error to the cost function is put forward. Two categories of trials are performed to validate the proposed method: feature extraction and classification. The experimental results show that the proposed method can be effective.
