Portrayal processing method and device based on continuous and discrete features

The invention discloses a portrait processing method based on continuous and discrete features. The method comprises the following steps: A, performing entity management, dimension management and fact management on data assets; b, performing bitmap mode-based portrait calculation on the data assets, and extracting portrait data from the data assets; c, performing detection and evaluation on the portrait data, including effective range inference and processing, completeness rate detection and missing value supplementation; and D, outputting portrait data based on a multi-channel delivery mode. According to the portrait processing method based on the continuous and discrete features, the requirements of professional portraits and universal portraits can be balanced, the key elements are fused, and the breadth problem of the professional portraits and the depth problem of the universal portraits are solved. 本发明公开了一种基于连续和离散特征的画像处理方法，所述方法包括步骤：A、对于数据资产进行实体管理、维度管理和事实管理；B、对数据资产进行基于位图模式的画像计算，从数据资产中提取画像数据；C、对于画像数据进行检测和
