概念格建格代码，模型的建立概念格（Concept Lattice）是一个以概念为元素的偏序集，它可以通过Hasse图可视化，其中每个节点是一个概念。概念格结构模型来源于形式概念分析（FCA）理论，是FCA中的核心数据分析工具，它本质上描述了对象（样本）与属性（特征）之间的关联。[1](The concept lattice (Concept, Lattice) is a poset of concept elements, which can be visualized by Hasse diagrams, where each node is a concept. The concept lattice structure model, derived from formal concept analysis (FCA) theory, is the core data analysis tool in FCA, which essentially describes the association between objects (samples) and attributes (features))
