Description
Technical Field
The invention relates to the technical field of network marketing and artificial intelligence, in particular to a rapid data intelligent analysis method for user behavior habits of an internet mall.
Background
The behavior habits of the users of the internet shopping mall are all carried out in specific scenes, and the users also know the products through the scenes, so that the users have different requirements in different scenes. If the product selling points are connected with the requirements of the user, the pain points of the user are effectively triggered by utilizing the scene, the emotional resonance of the consumer is caused, the purchasing desire is stimulated, and a good interaction relation can be established, so that the viscosity and loyalty of the consumer are formed. For the initial user or the user with less consumption information, the consumption habit of the user is difficult to dig out due to insufficient user information, and further, the user is difficult to provide targeted recommendation and the commodity transaction rate is improved. And the scene marketing can construct the display sequence of the commodities according to the previous and subsequent causal relationships or functions, and further give more targeted recommendations according to the current selection of the user, so how to rapidly construct the memory of the scene, and the memory is used as the basis of the subsequent user behavior habit statistics to become the basis of rapid intelligent analysis.
Brain-like learning is a hotspot of current research in the fields of artificial intelligence and machine learning. Hierarchical Temporal memory (htm) is a machine learning technique that mimics the processing mechanism of information by the human brain by simulating the organization and organization of cortical cells. HTM is essentially a memory-based system. The HTM network is trained by a large amount of time-dependent data, a large number of pattern sequences are stored, and the next possible input is predicted through the memorized pattern sequences.
Unlike the existing artificial neural network, the HTM takes cells as a basic unit and is managed in a hierarchical manner; several cells are firstly combined into a micro-column, and then the micro-column forms HTM network space. The spatial pool algorithm and the temporal pool algorithm are two important steps in training the HTM, and the spatial pool algorithm is first used to select some of the activated microcolumns from all the microcolumns to correspond to the current input. Selecting partially activated cells from the microcolumns by using a time pool algorithm to express and input the position information, and establishing association between input and output by adjusting relevant dendritic branches on the active cells to learn; and simultaneously using the active cells and the constructed dendritic branches to predict the input at the next moment.
The current time pool algorithm only uses a simple Hebbian rule, establishes the association between active cells at two adjacent moments before and after by adjusting the connection value of synapses in dendritic branches, and learns the characteristics of sequences; and the sequence learning task can be completed only after the connected synapses in the dendritic branches are accumulated to a certain threshold value. If a fast learning model is to be constructed, a novel time pool algorithm must be designed, and the efficiency and effect of the HTM learning sequence are improved.
