A review of technology for implementing real-time cosmetics recommendation system using PHP

With the development of society and the improvement of people's living standards, cosmetics have become very important to modern women. How to choose cosmetics that suit your skin type and style has become a problem for many women. The traditional way of purchasing is usually to listen to recommendations from others or through trials. However, since everyone's skin type and needs are different, there is a lot of uncertainty in this purchase method. How to accurately and quickly recommend suitable cosmetics for each user among a large number of cosmetics has become a research hotspot in the cosmetics e-commerce industry. This article will introduce a technical review of using PHP to implement a real-time cosmetics recommendation system.

1. Technical Principle of Cosmetics Recommendation System

The cosmetics recommendation system collects users’ historical behaviors, browsing records, purchase records and other data, and uses machine learning algorithms to analyze the user’s interests and needs. Analyze and then recommend corresponding products. In order to make the system more accurate and effective, the following technologies need to be implemented:

1. Data preprocessing

Data preprocessing is an important step in the recommendation system. Cosmetic recommendation systems need to collect a large amount of data, which often contains various noises and missing values. Therefore, before data processing, data cleaning, normalization, deduplication and other processes need to be performed to improve data quality and accuracy.

2. Feature extraction

Feature extraction is a technique that converts raw data into feature vectors that can be used in machine learning algorithms. In the cosmetics recommendation system, the feature vector can include information such as the brand, efficacy, applicable skin type, price, etc. of the cosmetics, as well as the user's historical behavior, purchase records and other information. Through feature extraction, this information can be converted into a data format that can be used for machine learning algorithms.

3. Machine learning algorithm

Machine learning algorithm is the core of the cosmetics recommendation system. In this process, the system recommends cosmetics that are most suitable for the user by clustering, classifying or predicting the user's historical behavior and preferences. Machine learning algorithms include collaborative filtering algorithms, content-based filtering algorithms, hybrid filtering algorithms, etc.

2. PHP technical solution for implementing real-time cosmetics recommendation system

PHP is a popular server-side scripting language, which is widely used in the field of Web development. If you want to develop an efficient, real-time cosmetics recommendation system, you can use PHP to build backend services, and combine it with open source machine learning frameworks and data mining libraries, as well as database technology implementation. The specific plan is as follows:

1. Database design

First of all, it is necessary to design a database suitable for the cosmetics recommendation system. The database needs to contain information such as the brand, efficacy, applicable skin type, and price of cosmetics, as well as the user's historical browsing records, collection records, and purchase records. You can choose relational or non-relational databases such as MySQL and MongoDB.

2. Select a machine learning framework

In PHP, you can implement algorithms by calling machine learning libraries in languages ​​such as Python or R. Common open source machine learning frameworks include TensorFlow, Scikit-Learn, PyTorch, etc.

3. Implement data preprocessing

Use PHP to implement data preprocessing, including data cleaning, normalization, deduplication and other processing to improve data quality and accuracy.

4. Extract feature vectors

Using PHP to extract feature vectors of cosmetics and users can be achieved through natural language processing technology and correlation analysis techniques.

5. Develop recommendation algorithm

You can choose algorithms based on collaborative filtering, content-based filtering, hybrid filtering, etc., analyze users based on feature vectors, and quickly recommend suitable for their skin quality and demand for cosmetics.

6. Real-time recommendation service

Combines recommendation algorithms with web applications to achieve real-time cosmetics recommendation services. For example, based on the user's browsing history and purchase history, we recommend cosmetics related to their interests.

3. Conclusion

This article introduces a technical review of using PHP to implement a real-time cosmetics recommendation system. Through technical means such as data preprocessing, feature extraction, machine learning algorithms and real-time recommendation services, an efficient cosmetics recommendation system can be quickly implemented to provide users with more accurate and personalized cosmetics selection services.
