Build your own PHP framework to implement the Model class (3) in the previous blog, we have implemented and improved the findOne method of the Model class. next we will implement other methods.
Let's look at the findAll method. this method is similar to findOne.
Public static function findOne ($ condition = null)
The simple linear regression model is described earlier, followed by the multiple linear regression model.Simple linear regression is a linear regression relationship between a dependent variable and an independent variable, whereas multiple linear regression refers to a linear regression relationship between a dependent variable and multiple independent variables. Compared with simple linear regression, multiple linear regression is more practical, b

Build your own PHP Framework (3) and build a php framework. Build your own PHP Framework (III), build a php framework, and then improve your PHP Framework. The main content of this update is: introduced the exception handling mechanism, improved exception and error handling,
of features and simplifies the model, improved training and prediction efficiency.
3. Once you have prepared a dataset, you can use a variety of conventional machine learning classifiers for classification. You can also use various methods to evaluate the advantages and disadvantages of the classifier, such as performance reports, accuracy, and recall rate, this part is omitted because I have already menti

This article is a description of the construction of a NLP project environment in the XING_NLP of the fork in GitHub with the N-gram language model, originally written in Readme.md. The first time to use the wiki on GitHub, think of a try is also good, but the format is very chaotic, they are not satisfied, so first in the blog Park record, and so on GitHub blog build success.1. Operating system:As Programe
recurring earnings.A special part of this business model of recurrent revenue is the very impressive amount of subsequent sales or customer acquisition costs that the first business brings. In previous trading models, each new business required a new and costly cost of sales support.If you're still in the business model of a lot of other businesses when you sneak up on recurring revenue, check out the exam

After the article was sent to the blog Park, a friend put forward a point: "This we can think of the creation of the time to solve the problem of duplication, but if it is update, I believe that such statements should also be reported wrong." That is, if this model is used to do update operations, verify that the user name exists and add operation will be a little different, because to exclude th
In our previous blog, we implemented and perfected the FindOne method of the model class, and we implemented the other methods below.
First look at the FindAll method, which is similar to FindOne.
PublicStaticfunctionFindOne($condition=NULL){$sql=' select * from '.Static:: TableName();$params=[];//Emptyif(!Empty($condition)){$sql.=' where ';$params=array_values($condition);$keys=[];foreach($condition as$key=$value){Array_push($keys,"$key = ?");}$sq
The RFM model: R (Recency) indicates how long the customer's last purchase was, and F (Frequency) represents the number of times the customer purchased in the most recent period, and M (monetary) represents the amount the customer purchased in the most recent period. The general raw data is 3 fields: Customer ID, purchase time, purchase amount, processed with data mining software, weighted (consider weight)
-person photos for reference, then the angle of the photo is very important, otherwise our model will be wrong and we'll have to spend a lot of time tweaking it. We also need to take into account the camera's focal length, the longer the focal length closer to the view of our reference model. In theory, however, because of the changes in the perspective of our photos are always different from the real peopl

EMF actually defines 2 kinds of meta model, called Ecore and Genmodel, respectively. Ecore contains the definition of the model, and we do this by creating a new and edited Ecore file when we create the EMF model. Genmodel contains information about the automatic generation of Java code (the Po
