Theory and formula please see Andrew Ng's machine learning in the NetEase public class, or the machine learning of Andrew Ng in CourseraFor multivariate linear regression to fit the best straight line, in order to make the error squared and the smallest, the method on the textbook is to seek the bias, and make it 0, and then solve the linear equation group.But there are many other ways to achieve this, and Andrew gives two methods of gradient descent in the case of large samples and small sample

Azure storage contains storage account, Container, blob, and so on, with the following specific relationships:Our commonly used blob storage is stored in the container of the storage account.There are currently three ways to share the contents of a BLOB with other users, in three ways:1. Set the Container property as a public container2. Set the Blob property to public public blobOnce set, the BLOB can be downloaded by wget.3. File sharing over a certain period of time via

However, the hot spare disk in the process, another hard drive offline, causing hot spare synchronization failed, two sets of RAID array crashes, LVM structure is incomplete, the file system is not working properly, the server data needs to be repaired. Two off-line hard drive detection, found that the first offline hard drive is not recognized, the initial inference is a hardware failure, the n

SAS and SATA Hard Drive guidelines When you add a hard disk drive to the server, follow these general rules: The system will automatically set all drive numbers If you are using only one hard drive, install the drive in the home with the smallest drive letter. When multiple drives are divided into the same drive array, these drives must have the same capacity to maximize storage space efficiency. Drives in the same logical volume must have the sa
