Design and implementation of Python-based movie recommendation system

Text box allows users to enter and edit text. In Python, use Tk.The Entry object or the wx.TextCtrl component in wxPython realizes the text box function. Checkbox The checkbox allows users to select multiple options.

Design system architecture: Design a suitable Python system architecture according to the topic and goals of the thesis. This includes choosing the appropriate Python library and framework, and how to combine them to achieve the required functions. In this process, you can refer to the existing open source projects and technical documents.

To implement a simple word recommendation system, you can use the following steps: prepare a word list and enter words. First, prepare a word list to find similar words. Then enter the word that the user wants to query.

Recommended system (III): Recommended algorithm based on matrix decomposition

Matrix decomposition funkSVD: This matrix decomposition is not like in the linear generation, and it belongs to pseudo-decomposition. The main idea is to replace the matrix of m*n with two m*k and k*n matrices. Because in the recommended system, the matrix is very sparse, the decomposed matrix is generally dense, and the empty value can be obtained by multiplying the row.

When the matrix decomposition idea appears in the recommended model, SVD (singular value decomposition) naturally comes to mind. SVD can decompose a matrix into the form of . The main diagonal in D is a singular value sorted from to to small. We select the first few singular values and the vectors corresponding to U and V to achieve it. Downsimension.

On the contrary, if the similarity is normalized, the coverage of the recommended system can be improved.

How to design a better recommendation system for the game web

1. On the one hand, always close Pay attention to user feedback, such as AI-based user experienceThe feedback system, on the other hand, should also increase the feedback mechanism to make it easier for users to make suggestions and opinions. In a word, designing a better navigation structure for the game web is an important way to improve the user experience.

2. Appropriately match various elements on the page to make the text, pictures and other contents on the page more coordinated, so as to design a good page layout.

3. At this time, it is more inclined to marketing. Generally, with the help of certain platforms and information websites, the official website is also launched. At this time, the official website has a relatively simple design and not much content introduction, but the picture is quite good and pays more attention to visual effects.

Write a word recommendation system with python?

It's okay. Although Python and Java are different programming languages, they all have many identical machine learning and recommended algorithm libraries, such as Scikit-learn, TensorFlow, Keras, Mahout, etc., so you can choose from these libraries. Choose a shared algorithm and use it in different programming languages.

Using Python for artificial intelligence and machine learning development, it can quickly build and train models, and apply them to image recognition, voice recognition, natural language processing and recommendation systems and other fields. Web development: Python is also an excellent language for Web development.

Graphics under Linux generally have two forms of qt and gtk, and the interface design is not bad.

Write code: You can use any text editor to write Python code. The specific content of the code is determined according to the needs of the program, which can include various Python native syntax, built-in functions, third-party libraries, etc. Run the program: You can use the Python interpreter to run the Python program.

I think it's better to use java. Java is an object-oriented programming language. Java language has two characteristics: powerful and easy to use. It has the characteristics of simplicity, object-oriented, distributed, etc. It can write desktop applications, web applications, distributed systems and embedded system applications, etc.

Stage 5: Crawler development Python full stack development and artificial intelligence crawler development learning content includes: crawler development practice.
