Question

我想通过亚当之类的不同算法来优化权重；随机梯度下降等，并使用sklearn的感知器尝试不同的激活函数，如下所示：

我在sklearn中没有发现该怎么做的建议

    (function ($) {

    $.fn.FileUpload = function (options) {

        var settings = $.extend({
            project: 'Default',
            parent: '1'
        }, options);

        var elem = document.createElement('div');

Answer 1

Perceptron()等效于SGDClassifier(loss=”perceptron”, eta0=1, learning_rate=”constant”, penalty=None)，因此按设计使用SGD。

您正在寻找的是sklearn.neural_network.MLPClassifier
