Construct a script engine using C language (2)
Author: kevin_qing
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.
1. Virtual Machine structure.
Considering that internal function definitions are not currently suppo
XXX: the document states that either an Intel CPU with VT (vmx) or an SVM (secure virtual machine, also known as a AMD-V) must be availableAMD CPUInstall. I installed it on turion 64 X2. No problem.Whether AMD and Intel CPU support VT or SVM. For details, referKernelHas_svm () and cpu_has_kvm_support () of KVM ()Function.1.

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
Ping 192.168.16.1

What is virtual software:
Virtual software allows you to run two or more Windows, LINUX, and other systems simultaneously on one machine. It can simulate a standard PC environment. This environment is the same as a real computer, there are chipset, CPU, memory, video card, sound card, network card,

intervention on the results of model training it's a lever. Model does not understand the business, really understand the business is people. What the model can do is to learn from the cost function and sample, and find the optimal fit of the current sample. Therefore, machine learning workers should be appropriate to the needs of the characteristics of some human intervention and "guidance", such as the hard rule to discard some noise characteristic
Support Vector Machine (SVM) is an original and not combinatorial classification algorithm with obvious visual geometric meaning, which has high accuracy.
The idea of using SVM algorithm: (1) Simple situation, the linear can divide the problem into a convex optimization problem, which can be simplified by Lagrange multiplier method, and then solved by the existing algorithm, (2) The complex condition, the linearity is not divided, the sample is projec
