Embodiment Construction
[0050] The following describes in detail the fast clustering method of commodity-related big data sparse network proposed by the present invention with reference to the accompanying drawings.
[0051] Such as figure 1 As shown, the present invention includes three clustering stages: (1) using a single-step linked list structure to store the common purchase relationship matrix of retail goods; (2) pruning the low-level commodity nodes of the commodity-related big data sparse network; 3) Use the idea of dividing high-value commodity nodes by low-value commodity nodes to quickly cluster commodity-related big data sparse networks.
[0052] The following specific examples illustrate the implementation process of the present invention. Assuming that there are 8 kinds of commodities, the sales records are as follows:
[0053] Sales records of 8 products
[0054]
[0055] Note: "√" in the form means that the product has been purchased.
[0056] Specific steps are as follows:
