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

Depending on your preferences, you can focus on: Blog: (Resource 1: "Basics of deep Learning" Resource 2: "Hacker's Neural Network Guide") Video: "Simplified deep learning" Textbooks: Neural networks and deep learning In addition to these prerequisites, you should also know the popular deep learning library and the languages that run

TensorFlow version 1.4 is now publicly available-this is a big update. We are very pleased to announce some exciting new features here and hope you enjoy it. Keras In version 1.4, Keras has migrated from Tf.contrib.keras to the core package Tf.keras. Keras is a very popular machine learning framework that contains a number of advanced APIs that can minimize the

Preface 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

Here is a keras,keras is also a very good depth learning framework, or "shell" more appropriate. It provides a more concise interface format that enables users to implement many model descriptions in very, very short code. Its back end supports the Te

Most layers in Caffe are written in C + +. But for the input of their own data to write the corresponding input layer, such as you want to go to the part of the image, you can not use Lmdb, or your label needs a special tag. This is the time to write an input layer in Python.As in FCN's voc_layers.py there are two classes:VocsegdatalayerSbddsegdatalayerContains: Setup,reshape,forward, Backward, Load_image, Load_label, respectively.
