: Reduce the size of the index Indexes are reduced, resulting in faster queries to the index Small index for adding and removing changes in the maintenance performance will be higher For example, the following statement: After we have set up a clustered index for it: At this point we add filter conditions to form a filtered index: From the above we can see that the use of filtered index of the scene to be related to the specific business scenario, for a large number of

Verilog Design AdvancedDate: May 6, 2014 TuesdayMain Harvest:1. Write the first Verilog program yourself.Topic:Using a 10M clock, a single-cycle shape such as the following periodic waveform is designed.Thinking:The first idea is to define two counters to count and two enable flags to control the two variables separately. But this logic is too complicated, search on the internet, or the definition of a counter is better.Verilog Program:Modulefdivision (CLK, RST, clk_out);Input CLK;Input rst;Outp

Cross-validation is a method of detecting whether a model is overfit. The most commonly used cross validation is the K-fold cross validation.The specific methods are:1. Divide the data evenly into k parts, 0,1,2,,,k-12. Use 1~k-1 data to train the model, and then use the No. 0 data for verification.3. The 1th data is then used as the validation data. Make a K loop. I finished k-fold cross validation.This cross-validation approach is characterized by the fact that all data are validated and train

Genetic algorithm is a kind of heuristic search, which belongs to evolutionary algorithm. It was originally designed according to Nature's natural choice of species and genetic laws. It simulates the natural selection, heredity and mutation of nature species, and improves the genes of a population.The genetic algorithm needs to set parameters such as crossover probability, mutation probability and iteration number, and the convergence of the algorithm
