主要讨论Adaline对权扰动敏感性的计算.鉴于Adaline的输入和输出的不连续性,敏感性定义为Adaline对于所有可能输入在权值发生扰动的情况下输出发生变化的概率.借助超球面模型和解析几何的技术,给出一个近似计算Adaline敏感性的方法.在输入维数足够大的情况下,该方法优于以往的其它方法.它在牺牲少量计算精度的情况下,极大地降低了计算复杂度,使得敏感性更具实用价值.
This paper mainly discusses the calculation of Adaline’s sensitivity to weighted disturbances.According to Adaline’s input and output discontinuities, sensitivity is defined as Adaline’s probability of output changing for all possible inputs perturbed by weights.Using the hypersphere model and The method of analyzing geometry is given and a method of approximating the sensitivity of Adaline is given. This method is superior to the other methods in the past when the input dimension is large enough, which greatly reduces the computational cost Complexity, making the sensitivity more practical value.
