Probabilistic relational neighbor classifier
Webb1 juni 2024 · Probabilistic Relational Classifier概率关系分类器 基本思想：某节点的label是其邻居节点的对应的label概率的均值。 首先初始化已经存在label的节点标签概率，正例是1，负例是0，对于没有标签的全部设置为0.5，然后对所有没有标签的节点进行概率更新，直到收敛或者得到最大的迭代次数。 （感觉是一个马尔科夫过程） P (Y i = c) = ∑(i,j)∈E W … WebbProvided are processes of balancing between exploration and optimization with knowledge discovery processes applied to unstructured data with tight interrogation budgets.
