p.s. SVM is more complex, the code is not studied clearly, further learning other knowledge after the supplement. The following is only the core of the knowledge, from the "machine learning Combat" learning summary. Advantages:The generalization error rate is low, the calculation cost is small, the result is easy to explain.Disadvantages:Sensitivity to parameter tuning and selection of kernel functions, the original classifier is only suitable for han
Preface: Today just heard a talk about Extreme learning Machine (Super limited learning machine), the speaker is Elm Huangguang Professor . The effect of elm is naturally much better than the SVM,BP algorithm. and relatively than the current most fire deep learning, it has a great advantage: the operation speed is very fast, accurate rate is high, can online sequential learning. The algorithm has not been

1.1 class Load Check
When a virtual opportunity comes to a new command, it first checks whether the parameter of the instruction can navigate to a class's symbolic reference in a constant pool, and checks whether the class represented by the symbolic reference has been loaded, parsed, and initialized. If not, the corresponding class loading process is performed first. 1.2 Allocating memory
Divides a certain size of memory from the Java heap into a newborn object.

The Dalvik virtual machine relies on the underlying POSIX-compliant operating system, which can simply complete process isolation and thread management. It has efficient use of memory and high performance on Low-speed CPUs. Each Android application has a separate Dalvik virtual machine instance at the bottom, and its code is executed with the virtual machine inte

Please note
Considering that the script compiler can be implemented independently as a process, and the compiler needs to debug the results of the script compiler,
At present, the development starts from the underlying Virtual Machine section.

Let's look at the example of predicting house price. We will first perform linear regression on the data, that is, the first graph on the left. If we do this, we can obtain such a straight line that fits the data, but in fact this is not a good model. Let's look at the data. Obviously, as the area of the house increases, the changes in the housing price tend to be stable, or the more you move to the right

How to connect the local Windows server to CentOS in the Virtual Machine and centos in the Virtual Machine
1. Determine the IP address of CentOS. The command is ifconfig. We can see that the LinuxIP address is 192.168.85.128.
2. the IP address of WIndows is 192.168.16.1,
3. Ensure the ping between CentOS and Windows
