High-quality electric power package recommendation method based on improved collaborative filtering algorithm

Abstract

The invention discloses a high-quality power package recommendation method based on an improved collaborative filtering algorithm, and the method comprises the steps: fusing the dominant demand score of a user and the implicit demand score of the user, and obtaining an implicit and implicit package score matrix based on the demands of the user; calculating the comprehensive package similarity among different high-quality power packages according to the high-quality power packages to obtain a nearest neighbor set of the high-quality power packages; weighting the score of the target high-quality power package by taking the comprehensive package similarity among the different high-quality power packages as a weight to obtain an initial prediction score of the target user on the target high-quality power package; calculating user similarity between the target user and other users to obtain a nearest neighbor set of the target user; for a high-quality electric power package of which the target user is not scored, weighting the high-quality electric power package through a nearest neighbor set of the target user to obtain a final prediction score; and forming a recommendation set by the first plurality of high-quality electric power packages with relatively high scores. According to the method, the problems of one-sidedness, low accuracy and cold start in the high-quality power package recommendation process are solved.

Description

technical field [0001] The invention relates to the technical field of intelligent electricity sales, in particular to a method for recommending high-quality electric power packages based on an improved collaborative filtering algorithm. Background technique [0002] With the in-depth development of my country's market economy, the promotion of power market reform is urgent. After the country launched the reform of the power system, it used market mechanisms to optimize the power supply guarantee mechanism and power source structure. Under the premise of ensuring necessary supervision, it gradually reduced government intervention in the power industry, and introduced market mechanisms in the determination of power prices and the provision of power services. , restoring the commodity attribute of energy. As an important electricity commodity, the electricity sales package is the carrier for electricity sales companies to provide users with electricity sales services. In ord...
