I am going to index the fields of a table in SQL server2005 today. The creation fails. Check the table structure. The original field is nvarchar (max) and cannot be indexed. Later, change this field to nvarchar (4000) and re-execute the create statement. The following prompt is displayed: Warning! The maximum key length is 900 bytes. The index 'ix _ project_label 'has maximum length of 8000 bytes. For some combination of large values, the insert/upda

Previously, a method of solving LR (linearregression), the norm equation (Normal equation), was discussed. This is the watermelon book on the method, which in Andrew Ng's public class also said a lot of other methods of solving parameters: Gradient descent (Gradient descent), which includes batch gradient descent (batch Gradient descent) and random gradient descent (Stochastic gradient descent).In addition, the probability interpretation of cost function and local weighted regression (

. In most cases, the pdflush and memory recovery mechanisms are independent of each other. When the kernel calls low on memory reclaim, lmr also calls pdflush to synchronize expired pages, in addition to other memory release operations. 5.6 case analysis: The vmstat tool also counts the usage of virtual memory while calculating the CPU usage. The following are some indicators related to VM memory in vmstat output: Column name Description

combined into a composite index. All columns in the composite index must be in the same table. The maximum size of the combined index value is 900 bytes. That is to say, the total length of a fixed-size column that compose a composite index cannot exceed 900 bytes. For more information about variable type columns in a composite index, see the comments section. [ASC | DESC] Determines the ascending or desce

columns, even if they are not referenced in the create index statement. When two or more columns are best searched as one unit, or many queries reference only the specified columns in the index, a composite index should be used. A maximum of 16 columns can be combined into a composite index. All columns in the composite index must be in the same table. The maximum size of the combined index value is 900 bytes. That is to say, the total length of a
