本文介绍了可变阈值概念格的定义。 基于Galois连接,定义了三种可变阈值概念格,通过调整阈值可以满足知识发现的各种要求。 可变阈值概念格中形式概念的数量远远少于模糊概念格中形式概念的数量。 三种可变阈值概念点阵在两个明快集合之间,在明快集合和模糊集合之间以及在模糊集和明晰集合之间构造。 它们的性质类似于经典概念格的性质,并且可以由模糊概念格来诱发。

使用ADWIN和朴素贝叶斯分类器的数据流中概念漂移检测 AdWin:自适应滑动WINdow算法 基于纸张: Bifet和R. Gavalda。 2007年。使用自适应窗口技术从时变数据中学习 class concept_drift . adwin . AdWin ( delta = 0.002 , max_buckets = 5 , min_clock = 32 , min_win_len = 10 , min_sub_win_len = 5 ) 参数 三角洲 置信度值 max_buckets 一桶排内的最大桶数 min_clock 用于减少窗口和检测变化的最少新数据数量 min_window_len 最小窗口长度,用于开始缩小窗口并检测变化 min_sub_window_len 最小子窗口长度,从整个窗口中拆分 方法 set_input ( value ) 将输入值
