A smoothed version of the objective function (otherwise, piecewise constant) is locally optimized using a gradient-type method. See also [189]. Prototype selection [154,189] is another source of mathematical optimization problems in k-nearest neighbors methods. Classifying a forthcoming individual x ...
To this end, we can use either a sigmoid function or a softmax function. Eqs. (6.1) and (6.2) show a sigmoid function and a softmax function, respectively: (6.1)S(xi)=11+e−xi=exi1+exi, (6.2)S(xi)=e−xi∑k=1ne−xkk=1,…,n, where n denotes the number of output ...
