MMVM mode. View is bound to ViewModel and then executes some commands to request an action from it. In turn, ViewModel communicates with model, ViewModel tells the model update to respond to the UI. This makes building UI designs for apps relatively independent and easy to replace with UI design ("Do whatever you want" to design your interface). At the same time, as the UI and functionality be

Machine Learning: this paper uses the analysis of the taste of red wine as an example to describe the cross-validation arbitrage model. The least squares (OLS) algorithm is commonly used in linear regression. Its core idea is to find the best function matching of data by minimizing the sum of squares of errors. However, the most common problem with OLS is that it is easy to over-fit: that is, the attribute
