The disadvantage of this is that the computational changes are large. The solution is to first use the 1*1 convolution compression channel number (refer to "Deeplearning.ai convolutional neural network Week 2 Lectures notes").4.

The process of Alphago Zero (hereinafter referred to as zero) is shown in Figure A, B, in each state s, through MCTs search, to obtain the probability p of each possible move, where MCTs search adopts Self-play and executes the fθ strategy. Fθ mainly uses Microsoft's ResNet, that is, based on the residual learning. After using MCTs to obtain the probability p of each possible move, update the fθ weight. Finally, use this fθ to evaluate

The main problem with CNN for semantic segmentation is the reduction in resolution caused by repeated sampling operations. Refinenet proposes a multipath improved network to extract all the information from the sampling process and to obtain high-resolution predictions using long distance residual connections. With the characteristics of fine layers, the high-level semantic information can be improved. In addition, the paper uses chain-type residuals to obtain rich background knowledge.

This article will be the latest and most complete evaluation of a depth learning framework since the second half of 2017. The evaluation here is not a simple use evaluation, we will use these five frameworks to complete a depth learning task, from the framework of ease of use, training speed, data preprocessing of the complexity, as well as the size of the video memory footprint to carry out a full range of evaluation, in addition, we will also give a very objective, Very comprehensive

The original Faster r-cnn used ZF and Vgg, which were pre-trained on ImageNet, but there were many different networks, and the number of parameters varied greatly in different networks. For example, Mobilenet, a small, efficient framework with a speed preference of about 3.3 million parameters, while ResNet
