I. Overview In the multidimensional analysis of business intelligence solutions, the common models can be divided into star model and snowflake model According to the relationship between fact table and dimension table. When designing a model of logical data, you should consider whether the data is organized according to the star
Label: style blog HTTP Io ar use for SP strong I. Introduction This document is based on Andrew Ng's machine learning course http://cs229.stanford.edu. In the previous supervised learning regression model, we used the training set to directly model the conditional probability P (Y | X; θ). For example, Logistic Regression uses hθ (X) = g (θ Tx) Modeling P (Y | X; θ) (where g (z) is the sigmoid functio
A Brief Introduction to the Snake Model Based on the Active Contour Model of image cutting (5) [Email protected] Http://blog.csdn.net/zouxy09 In "image cutting (I) Overview", we have briefly understood the mainstream image cutting methods. Below we will mainly learn the energy functional-based cutting method. Here we will learn a simple knowledge of the Snake model
Today, when the business is completed to a certain extent, I checked the code and suddenly found that the current code is a bit strange. It is strange that there are many files in my model. Each file corresponds to a table in the database, and there is almost no logic code in each model. For example: What is the reason? Because the rdb_model class implements Orm, I inherit this class to use the operation
Problem When loading a model from a disk, it is often too large or too small. You want to scale the model to the defined size. Solution First, you need to define a global ball for the model. The previous tutorial has explained this. Now that you know the ball, you can know the current size of the model. From this dim

list of the basic code for the simple factory pattern. In fact, it is quite simple, right, only a layer of inheritance relationship, a dependency, in the factory class with the switch statement to determine what type to instantiate, then calculate, get the results. Factory method ModeThere is a mention of the factory class mode in the simple factory model above. To help you recall the simple factory model
MVC model binding and mvc model bindingMVC model binding In WebForm, the value of the submitted Form is generally obtained in the Form of Request. Form ["Title. The model binding mechanism is provided in MVC. It makes it easier to obtain parameters in a form or Url in the background.I. Basic
the difference between a simple factory model and a factory method pattern The biggest advantage of a simple factory model is that the factory class contains the necessary logical judgments, dynamically instantiating the related classes according to the client's selection criteria, and to the client, the dependency on the specific product. The factory method pattern defines an excuse for creating objects,
How to make a correct design direction. How to make a correct design direction. When preparing gifts for parents, friends, and lovers, we usually prepare different surprises that meet the needs of the audience. We tend to stand in each other's life scene to think about whether our gifts are appropriate and make the final choice. In the design, designers can easily put their own design preferences into the work, and forget the design of users, the ultimate consumer, has been addicted to their
from: http://www.iteye.com/topic/283668 Recently, Taowen has launched two consecutive discussions on anemia models and field models, which has aroused extensive and heated discussion, but I think it is debatable what the outcome of the discussion (or controversy) is. The problem is that the anemia model and the domain model have their own views, if there is no consensus on this concept, then the outcome of
Transferred from: http://www.uml.org.cn/mxdx/200907132.asp In the current developer community, there is a widespread prevalence of an architectural pattern known as the anemic domain model by Martin Fowler. The model has been blamed for the criticism of the master. This model has a fatal flaw: it often behaves poorly in dealing with complex areas. There are many

Next we will mainly learn the energy functional-based segmentation method. Here we will learn the simple knowledge of the Snake
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
