Cigarette consumption studying and determining method based on collaborative filtering algorithm and clustering algorithm

Abstract

The invention relates to a cigarette consumption studying and determining method based on a collaborative filtering algorithm and a clustering algorithm. The method comprises the following steps of 1), collecting samples, namely collecting preference of a sample consumer to each cigarette product; 2), collecting characteristics, namely selecting a plurality of characteristic values of user characteristic information for constructing a consumer characteristic vector and obtaining a consumer characteristic matrix; selecting a plurality of characteristic values of commodity characteristic information for constructing a cigarette characteristic vector and obtaining a cigarette characteristic matrix; 3), clustering, namely performing clustering on consumers and cigarette by means of a K-means++ algorithm; and 4), calculating the preference, namely obtaining the preference of the consumer to each cigarette product through the collaborative filtering algorithm. According to the cigarette consumption studying and determining method, the consumers and the cigarette are clustered by means of the K-means++ algorithm, and then the preference of a certain consumer to a certain cigarette product is measured through the concept of the collaborative filtering algorithm. Furthermore through the preference of a sample consumer, a consumption requirement of an individual consumer is predicated.

Description

technical field [0001] The invention relates to the field of tobacco sales, in particular to a method for researching and judging cigarette consumption based on the combination of a collaborative filtering algorithm and a K-means++ clustering algorithm, so as to research and judge the consumption demands of individual consumers. Background technique [0002] Cigarettes have "dual attributes" of both value and harm, which determines that the tobacco industry must implement the national tobacco monopoly system. However, with the development of the economy and society, the market-oriented requirements of the tobacco industry are constantly increasing, and the balance between planning and the market is constantly tilting towards the market. In order to grasp the market demand more realistically, produce more marketable products, and carry out more scientific supply of goods, the National Bureau strategically proposed to carry out market demand forecasting work. Since 2003, the ...
