Http://www.cs.princeton.edu /~ Blei/topicmodeling.html Topic models are a suite of algorithms that uncover the hidden thematic structure in document collections. These algorithms help us develop new ways to search, browse and summarize large archives of texts. Below, you will find links to introductory materials, corpus browsers Based on topic models, and open source software (from my research group) for topic modeling.Introductory Materials I wrote a general introduction to topic

The ORACLE tutorial is: Modeling and Design of Oracle databases. To develop a database-based application system, the most critical step is the database modeling design on which the entire system is based. From logical to physical, the design is neglected in one link, the entire application system is built on a dangerous building. As the development process continues to deepen, it must face various difficult

Today, in the course of the software design, the teacher mentioned the software modeling, he suddenly became interested in this.Software analysis modeling embodies the idea of software design, which is a bridge between system requirement and system realization. The software engineer develops a software system that conforms to the design goal according to the model established by the designer, and the softwa

The quality of BI modeling directly affects the quality of the Data Warehouse project, so there is a clear definition of the structure, size, and model capabilities of the data Warehouse before modeling.There are many factors that affect the modeling of BI Data Warehouse, which often change depending on the specific circumstances of the project. But some of the principles are interlinked, the implementation

Opencascade Ring Type Spring Modeling[Email protected]Abstract. The directly create an edge was to give a 3D curve as the support (geometric domain) of the edge. The curve maybe defined as a 2D curve in the parametric space of a surface:pcurve. When you understand the Pcurve, you can modeling some interesting shapes, such as bottle neck thread, Helix spring, Ring T Ype Spring. ETC. The paper is focus on the

Understanding IBM SPSS Modeler and database integration and optimization In the first part of the three-part series on IBM SPSS Modeler and Database Integration modeling and optimization, we talked about using database nodes to write and read data to a database. Next, we'll introduce the use of SPSS Modeler applications to build, score, and store models in a database. Through integration, the analysis function and usability of SPSS Modeler can be com

stands for several, or dozens of, not too many) For example, each person will have multiple address. In this case, we modeled with the simplest embedded document. {name: ' Kate Monster ', id: ' 123-456-7890 ', addresses: [{street: ' 123 Sesame St ', City: ' Anytown ', cc: ' USA '}, {Stree T: ' 123 Avenue Q ', City: ' New York ', cc: ' USA '}]}This modeling approach incorporates the obvious advantages and disadvantages: Pros: You don't need to execut

1. Description of Domain Modeling Domain Modeling is not a new concept. Domain Modeling expert Eric Evans has started using domain driven design since he published domain driven design in. After Tsinghua University published a Chinese version in, domain-driven design was widely used in some web projects. It is worth noting that the domain model is not only applic

the application of this SOA architecture ?? This is a very important issue.Lone Star (hidden QQ number) 22:39:41Architecture is a design drawingLotte (QQ number hidden) 22:39:57SOA architecture is different from the previous software architecture. The main difference is loose coupling.David (hidden QQ number) 22:40:14Yes. I agree!David (hidden QQ number) 22:40:34But it's a design drawing. What is the design?Lotte (QQ number hidden) 22:40:38This loose coupling is implemented by servitization of

The previous article refers to the Han O Sinox unmanned factory, certainly more advanced than the current automation production line. We see the Automation factory robotic arm is the automation component, but only a relatively fixed operating mode, the operating position is very fixed, only some simple mode. For example, the screw, the estimated offset, the manipulator is powerless, that is, the manipulator is not too smart, the first is no eyes, and then can not arbitrarily change position. Thi

Biological system modeling refers to the work of establishing mathematical models for the behavior, parameters and relationships of biological cells, organs and whole layers by applying the principles of modern physics and mathematics.Organisms are very complex systems, even the simplest red blood cells contain physical and chemical side about 2000 kinds of metabolic reactions, and the complexity of the brain is more incomparable. The study of this co

Use models to facilitate communication and generate useful documents.Use this practice to create a model with appropriate styles and classifications to drive development activities. This practice enables the team: Communicate System Requirements, structures, and behaviors. Observe the different perspectives of the system and understand the relationships between different perspectives. Use a model that can meet your needs. Make them more agile in mo
