1. there are two models: the congestion model and the blood loss model. The general practice is that the model is the model, and there is no way to operate it. It only has attributes. This model is called the blood loss model (whi
Template models mainly includes templatevariables and language ).
The template model can be applied to an infinitely large Bayesian Network;
The template variable is a variable that has been reused multiple times:
Such as location (time), genotype (characters), tags (pixels), difficulty (course), and so on.
Language is used to describe how template variables inherit Dependencies from templates.
There are many languages, and various languages have

MongoDB: Data Model introduction, mongodb Data Model
Data in MongoDB has a flexible mode. Unlike SQL databases, you must determine the mode of a table before inserting data. The MongoDB set does not force the structure of the document. This flexibility facilitates ing documents to objects or objects. Each document can match the data field that represents the object, even if the data changes significantly. H

The physical data model (Physical Data Model) PDM provides the basic elements required for the initial design of the system and the relationship between related elements; the physical design stage of the database must be detailed on the basis of the background design, including the database stored procedures, operations, triggers, views and index tables;

In addition to using the entity Framework in ASP. NET MVC, you have several options. For example, you can use other O/RM tools, such as Microsoft LINQ to sql,nhibernate or subsonic, to create your MVC model class.1.

The Ising model (Ising model) is one of the simplest and can provide very rich physical content of the model. It can be used to describe very many physical phenomena, such as: ordered-disordered transformation in alloys, transition from liquid helium to super-flow, freezing and evaporation of liquids, properties of glass material, forest fire, urban transportatio
The OSI reference model has many similarities with the TCP/IP reference model. They are based on the concept of an independent protocol stack. In addition, the features of the layer are similar. For example, in the two models, the transmission layer and above all provide end-to-end and network-independent transmission services for processes that want to communicate. These layers form a transport provider. S

What are two models?
We have come to these two concepts from a few words:1, machine learning is divided into supervised machine learning and unsupervised machine learning;2, supervised machine learning is known as training set data categories to train the classifier, unsupervised machine learning is not aware of the category of training sets to train the classifier;3, so that the supervised machine learning can be abstracted as a task of classification, and the basic completion of unsupervised i

Simply put, domain ojbect contains domain logic that does not depend on persistence, and those that rely on persistence are separated to the service layer.Service (business logic, transaction encapsulation) --> Dao ---> domain object Advantages of th
