A Note on Non-negative Matrix Factorization


A Note on Non-negative Matrix Factorization – This paper proposes a method for computing the posterior distributions of multiple matrix factorization (MPC). The method exploits prior information of the underlying matrix matrix. The posterior has a convex form, which is a compact representation of the matrix. The posterior is computationally efficient, but not exact. We show that the problem is NP-hard for a linear framework. This is due to a constraint which requires the posterior $p(1)$ be known. We then make a generalization of this constraint. We extend it to the framework of matrix factorization and show that for a linear framework, then the method is computationally and surely efficient.

Multispectral (SV) cameras are capable of capturing complex scenes. Unfortunately, there is less than a decade of empirical work on SV cameras. One challenge is that these cameras are very sensitive to low-resolution images and low-speed (2Hz) video. SV cameras are particularly fragile, vulnerable to low spatial resolution images and low spatial resolution video, respectively. In this paper, we propose the use of deep representations for image semantic segmentation. We first present a method to infer the semantic segmentation map from a high-resolution image. Next, we model the low-resolution depth map as a VLAD (visual semantic segmentation map) and use a deep learning algorithm to learn the semantic segmentation map based on two convolutional neural networks trained on the low-resolution data. Extensive experiments show that our method outperforms state-of-the-art SV segmentation algorithms.

A hierarchical visual classification framework based on the temporal temporal structure of images is proposed.
