Embodiment approach
[0044] Such as figure 1 As shown, the first aspect of the embodiments of the present invention provides a method for adaptively generating power communication planning indicators based on user behavior, and the specific process is as follows:
[0045] S1: Determine the user type based on historical data information, and recommend different index content according to the user type.
[0046] For new users, use the high-frequency index as the user's index selection recommendation;
[0047] For old users, user preferences are obtained through historical data information, and user preference indicators are used as user indicators to select recommendations.
[0048] S2: Select explicit and implicit indicators according to user behavior records, and perform indicator fusion through indicator selection to determine the user's initial score and initial score matrix P for the content of the indicator template.
[0049] S3: Determine the similarity matrix B between the indicator template...

The invention discloses a power communication planning index adaptive generation method, system and device and a medium. The method comprises the steps: recommending different index contents according to user types; recording explicit and implicit index feedback according to the user behavior, performing index fusion through the index feedback, and determining an initial score matrix of the user to the index template content; determining a similarity matrix between the index templates according to the cosine similarity between the index templates; and forming a user scoring matrix after collaborative filtering according to the scoring matrix and the similarity matrix. determining an important index set in the index template according to the user scoring matrix and the important index frequency of the index template, taking the important indexes in the set as network model input, determining an associated index template derived from the important indexes, and forming an architecture model generated by the electric power communication planning index template in which high-frequency index recommendation, collaborative filtering recommendation and important index recommendation are mutually collaborative.
Description
technical field [0001] The invention belongs to the technical field of power communication systems, and in particular relates to a method, system, device and medium for self-adaptive generation of power communication planning indicators. Background technique [0002] With the advent of the era of "big cloud, big things, smart things", the status quo of power systems generating a large amount of data has long become the norm. All aspects of the power system can easily obtain high-quality information content through information processing technology and tools. However, due to the huge amount of information, it is difficult to obtain the precise information required by users by means of information processing. And because different systems have different concerns and data selection methods, meeting the professional needs of specific power system links is a key issue that needs to be solved urgently. [0003] In order to solve the selection of massive data indicators, for the ...
