Abstract

The invention discloses a downsampling method based on popularity sorting. The problem that the media assets recommended by the recommendation service are concentrated in a small amount of hot media assets is solved. The downsampling method based on popularity sorting comprises the following steps: acquiring a first negative sample set meeting a first preset condition, and performing popularity lifting sampling on the first negative sample set according to a popularity lifting function; the first preset condition is used for representing that the exposed individual is not clicked in the first preset time; acquiring a second negative sample set meeting a second preset condition, and performing random downsampling on the second negative sample set; the second preset condition is used for representing that the individual meets the first preset condition and is continuously exposed within second preset time; obtaining a positive sample set meeting a third preset condition, and performing heat suppression sampling on the positive sample set according to the heat suppression function; and combining the first negative sample set, the second negative sample set and the positive sample set.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a down-sampling method based on popularity ranking. Background technique [0002] When a terminal device provides recommendation services, it relies on a pre-trained recommendation model, and the training of the recommendation model depends on the construction of training samples. To a certain extent, the sample quality determines the upper limit of the ranking model, so the training samples need to be carefully selected. The process of sample selection is called "downsampling". [0003] At present, the downsampling method is mainly implemented around popular suppression. The mainstream method comes from the inspiration of word2vec's downsampling—the word frequency indicates the popularity of a word, and the sampling rate of the word is calculated according to the word frequency. In natural language, the vocabulary is generally on the million level, and the frequency of...
