Original: Image classification in 5 MethodsAuthor: Shiyu MouTranslation: He Bing Center
Image classification, as the name suggests, is an input image, output to the image content classification of the problem. It is the core of computer vision, which is widely used in practice.
The traditional method of image classification is feature description and detection, such traditional methods may be effective for some simple image classification, but the traditional classification method is overwhelmed
The inverse propagation algorithm (back-propagtion algorithm), BP learning is a supervised learning algorithm, which is an important method of artificial neural network learning, which is often used to train feedforward multilayer perceptron neural networks.First, the principle of BP learning1. Feed-forward neural networkRefers to the network in the processing of

Learning ASP. NET's complete process !, Learning the asp.net Process
If you have more experience in object-oriented development, skip the following two steps:The first step is to master a. NET Object-Oriented language, C # Or VB. NET. I strongly oppose learning ASP. NET without a systematic understanding of an object-oriented language. ASP. NET is a comprehensive
painful process to look at the kernel, and there was a way to find a way out in the forest. In the meantime, I organized some students to learn the kernel, and there were almost a few who could stick to it. I think I have persisted. In the first and second scenarios, I hardly touched the door. There are three reasons for my analysis: 1. My own infrastructure is poor, which is the most critical. 2. the kernel itself is very difficult. 3. No communication or expert advice. It was the third time t

I have been busy studying recently and feel that it takes too little time to sum up. It sounds very entertaining, just like in "love of the city", Fan liuyuan said: at that time, I was busy with falling in love, where I had time to fall in love. The same is true for
Scala learning notes, scala Learning
The notes are complex!
1. The Singleton objects in Scala are decorated with objects, similar to static classes in C ++. When calling its internal functions, you can call them directly using the object name. You cannot apply for a new function!
2. A file can define classes and Singleton objects with the same name. A singleton Object is called a Companion Object of a class
Quick learning of the Six Thinking Skills of JavaScript and quick learning of javascript
When we are learning JavaScript or any other coding skills, it is often because of these obstacles:
Some concepts may cause confusion, especially when you switch from other languages.

In a flash to Beijing Java training one months past, in this one months I know a lot of teachers and classmates, let me have a kind of back to school feeling, the study atmosphere is very good, each student is very diligent study, some basic good classmate also is willing to help others, classmates mutual care, mutual help, Solve a lot of learning problems, said to thank my deskmate, without his help I think I will learn very hard, each encounter prob

The shortcoming of DCF series tracking algorithm is analyzed and improved.
One of the core of this thesis: DCF as a convolution layer in CNN;
The core of this paper is to integrate feature extraction, response graph generation and model updating into CNN for End-to-end training;
In the core of this paper, the idea of residual learning is used to update the depth target tracking network, which can deal with the large and small cha
