中文版:马尔可夫熵率计算器
原理:马尔可夫链的熵率 H = Σ π_i·H_i,即按平稳分布 π 对每个状态的一步条件熵加权平均——它回答「这条链长期平均每步产生多少比特的新信息」。独立同分布序列的熵率就等于分布熵;完全确定的链熵率为 0。
步骤:① 输入行随机转移矩阵;② 点击计算;③ 读出平稳分布、各状态条件熵与熵率。
示例:P = (0.5, 0.5; 0.25, 0.75) 时 π = (0.333333333333, 0.666666666667)、熵率 = 0.874185416306 比特/步——介于两行熵 1 与 0.811278124459 之间。
注意事项:行和必须为 1 且链需不可约(否则平稳分布不唯一,高斯消元会报奇异);熵率只关心长期行为,与初始状态无关;文本、DNA、股价对数收益都可用熵率度量「每符号平均信息量」。
