Embodiment Construction

[0060] The matching recommendation method of the content-based user personalized product of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: the specific implementation steps of the user-based random batch sampling method are as follows:

[0061] Step 1: sort out the interaction information files, user information files, product information files and divide the test set and training set.

[0062] The data set used should include no less than 100,000 user product interaction records and corresponding user personal information and product content information; take the public data set MovieLens 100k movie recommendation data set as an example, the data set contains 943 users (1-943 ) for the rating (1-5) data of 1682 movies (1-1682), each user has at least 20 evaluation records, and three files are sorted out from the used data set:

[0063] ratings: Each line of data includes [user id, movie id, rating]...

Abstract

The invention discloses a content-based matching recommendation method for user personalized products, which overcomes the problem that the recommendation algorithm in the prior art still needs to be improved. The invention includes step 1, user-based random batch sampling method; step 2, content-based user-product matching method: establish a network; according to batch input based on user-based random batch sampling method, orderly user ids are obtained, and a list of product ids is recorded in history , a set of target product id and label, train, adjust, and evaluate the network model on the training set, verification set, and test set respectively; input a specific user and its history, and use the content-based user-product matching network to predict its response to all unwatched Score and sort the movies, and finally output top-N recommendation results. The invention adopts a lightweight neural network, which greatly reduces the training time and training equipment requirements, the sampling process is easy, the model input is more random, and the generalization ability of the prediction result is stronger.

Description

technical field [0001] The invention relates to the field of recommendation algorithms, in particular to a method for matching and recommending content-based user personalized products. Background technique [0002] With the development of the Internet age, the phenomenon of information overload is becoming more and more serious, users are faced with more and more product choices, and the competition between products is getting bigger and bigger. A recommendation algorithm is an algorithm that matches users and products. A good recommendation algorithm can not only save user time and increase user satisfaction, but also increase product acceptance rate and drive transaction growth. [0003] Existing recommendation algorithms generally use collaborative filtering algorithms to pre-train the user-product interaction information matrix to obtain product latent factors and user latent factors, and then use the pre-trained latent factors to train the recommendation model to obta...
