I believe many of my friends, whether engaged in development, architecture, or DBA, often hear the word "tuning. Speaking of "tuning", it may make many technical staff feel excited, or it may make many people feel distressed. Of course, there are also many people who despise this because not everyone is exposed to a large number of projects, and not everyone does have high performance requirements. In mains

The main advantage is that the same effect can be achieved in a shorter period of time compared to training from scratch.Example:1.fine-tuning: Start with CNN training on cifar100, then just modify the last layer Softmax the number of output nodes (100 to 10), and then put on the CIFAR10 training.2.

Train with someone else's trained network model, if you have to use the same network as someone else, because the parameters are based on the network. Of course the last layer can be modified, because our data may not have 1000 classes, and only a few. Change the name of the output category and layer on the

Trust a lot of friends, whether it is to do development, architecture, or DBA, are often heard that the word "tune". Speaking of "tune", may let a lot of technical staff heart surging, may also make a lot of people feel distressed. Of course, there are a lot of people are dismissive of this, because not everyone has access to the project is very large, and not everyone does the project is very high performance requirements.

8.5.1 Index and system performance Indexing speeds up data retrieval, but it slows the insertion, deletion, and updating of data. In particular, the cluster index, the data is stored in a logical order in a certain physical location, when changing data, according to the new data sequence, the need to move a lot of data physical location, which will increase the burden of the system. For non-clustered indexes, the index pages need to be updated when the data is updated, which also takes up the s
