sample cardinality (up to 200), and some combine two sub models to handle both fast and slow updates. In fact, the selection of replaced samples to update the background model, in essence, is the sample life problem, the traditional way to use the first out of the replacement strategy. The probability of each sample being selected as a replacement sample is equal in the vibe background model, which is independent of the length of the sample's existence time, which guarantees that the sample lif

There is a problem that has plagued web designers for a long time: Should the use of fixed , mobile, elastic, or mixed layout ? They each have advantages and disadvantages.

Stored procedures improve the reusability of execution plans by explicitly converting the variable portions of the query to parameters. This enables the execution plan to be reused when the query is resubmitted with the same or different values in a mutable part. A stored procedure contains a complex set of SQL statements, which makes the execution plan of the build stored procedure somewhat expensive. Therefore, it is often advantageous to reuse the execution plan of a stored procedure instead

1. Decision Tree　　applicable conditions: The data of different class boundary is non-linear, and by continuously dividing the feature space into a matrix to simulate. There is a certain correlation between features. The number of feature values should be similar, because the information gain is biased towards more numerical characteristics.　　Advantages: 1. Intuitive decision-making rules; 2. Nonlinear characteristics can be handled; 3. The interaction

number of users in use.NTFS file system benefits: NTFS partitioning has high security and stability and is not easy to produce file fragmentation in use. It can record the operation of the user, through a very strict restrictions on user rights, so that each user can only follow the system-assigned permissions to operate, and fully protect the system and data security. In addition, for most users, the most intuitive advantage of NTFS is that the size of a single file breaks the 4GB limit of FAT
