Embodiment Construction
[0050] Referring to the accompanying drawings, the method for fast clustering of commodity-associated big data sparse networks proposed by the present invention will be described in detail below.
[0051] Such as figure 1 As shown, the present invention comprises three stages of clustering: (1) utilize the single-step linked list structure to store the common purchase relationship matrix of retail goods; (2) pruning the low-degree commodity nodes of the commodity association big data sparse network; ( 3) Using the idea that high-value commodity nodes are divided by low-value commodity nodes to quickly cluster commodity-associated big data sparse networks.
[0052] The implementation process of the present invention will be described below with specific examples. Assuming that there are 8 types of products, the sales records are as follows:
[0053] Sales records for 8 items
[0054]
[0055] Note: "√" in the table indicates that the product has been purchased.
