Basic usage of css3, which must be viewed by beginners (comparison between css3 and jquery animation) Step 1: Define an animation. The name can be different, just like the method name.1. Define an animation named fadeIn @-Webkit-keyframes fadeIn {0% {opacity: 0;/* The initial State transparency is 0 */} 50% {opacity:

Before developing the agent program, you must first understand the development process of the agent program. Only after you are familiar with the development process can you understand how to develop the agent program. Because of the running environment and platform-specific differences, the development process of j2se is different from that of j2se, which is much more troublesome than that of j2se. The general process of the development of J2EE is as follows: 1. Compile the Java source code and

specific research. For example, in the recommendation system, after basic computing, the competition still fails to achieve good results, because data preprocessing is very important, whether in the competition or in the project, data preprocessing requires many machine learning algorithms. I don't know much about my work, but what I learned after three months of practice is that machine learning is not used much. I often find rules and filter data, which is endless...
