[Turn] don't grind, you're an image recognition expert after this.

Image recognition is the mainstream application of deep learning today, and Keras is the easiest and most convenient deep learning framework for getting started, so you have to emphasize the speed of the image recognition and not grind it. This article allows you to break through five popular network structures in the shortest time, and quickly reach the forefront of image recognition technology.

efficient. An obvious trend is the use of modular structure, which can be seen in googlenet and ResNet, this is a good design example, the use of modular structure can reduce the design of our network space, and another point is that the use of bottlenecks in the module can reduce the computational capacity, which is also an advantage. This article does not mention some of the recent mobile-based lightweight CNN models, such as mobilenet,squeezenet,shufflenet, which are very small in size, and

(If you have the ability, visit the original CS229 on youtube or Netease open course ). The svm API documentation is very well-developed, and it is not very difficult to adjust the bag. However, in most data mining competitions (such as kaggle), SVM is often inferior to xgboost. 3.4) Neural Network) Compared with the industry's top Neural Network Libraries (such a
