Abstract
Video-based convolutional neural networks (CNNs) involve a large amount of training parameters, leading to the enormous computational complexity, which thereby delays the network convergence. Therefore, training successful CNN for action recognition rapidly is non-trivial. In this paper, a novel encoding called nonlinear gated channels unit (NGCU) is proposed to facilitate network training by encoding the global channel-level relationship. Based on this, nonlinear gated channels network (NGCN) is constructed for the end-to-end encoding, and the corresponding convergence performance is evaluated on the standard benchmarks UCF101 and HMDB51. Experimental results demonstrate that the proposed method is conducive to the convergence process of CNN based action recognition models.
