Deep learning is successfully used in many areas.

In this paper, we propose a deep learning model for BoW data. Based on the idea introduced in the framework of SVMs that has achieved a better performance in BoW count vector inputs, the proposed model assigns each feature to a latent vector, and each sample is represented by a distribution of the latent vectors of features contained in the sample. To transform the distribution efficiently and nonparametrically to the inputs of deep learning, we integrate kernel mean embeddings and a random Fourier feature algorithm. Our experiments verify the effectiveness of the proposed model on BoW document datasets. Because the proposed model is a general framework for BoW data, it can be applied directly to various supervised and unsupervised learning tasks.
