随机森林
说明: 用N来表示训练用例(样本)的个数,M表示特征数目。
输入特征数目m,用于确定决策树上一个节点的决策结果;其中m应远小于M。
从N个训练用例(样本)中以有放回抽样的方式,取样N次,形成一个训练集(即bootstrap取样),并用未抽到的用例(样本)作预测,评估其误差。
对于每一个节点,随机选择m个特征,决策树上每个节点的决定都是基于这些特征确定的。根据这m个特征,计算其最佳的分裂方式。
每棵树都会完整成长而不会剪枝,这有可能在建完一棵正常树状分类器后会被采用)。(N is used to represent the number of training cases (samples), and M is used to represent the number of features.
The number of input features m is used to determine the decision result of a node in the decision tree, where m should be far less than m.
From N training cases (samples), n times are sampled in the way of put back sampling to form a training set (i.e. bootstrap sampling), and the unselected cases (samples) are used to predict and evaluate the error.
For each node, m features are randomly selected, and the decision of each node in the decision tree is determined based on these features. According to these m characteristics, the best splitting mode is calculated.
Each tree will grow completely without pruning, which may be adopted after building a normal tree classifier).)

ffmpeg.js-master
说明: 使用ffplay播放视频源时,rtsp/rtmp等,会有一定的延时,这里我们可以通过设置ffplay播放参数将延时控制到最小。(When using ffplay to play video source, RTSP / RTMP and so on will have a certain delay. Here we can control the delay to the minimum by setting ffplay playing parameters.)

扫雷游戏先说下原理,原理其实很简单,设法获得“雷区”的数据,然后通过模拟鼠标动作,点击雷区上非地雷的的格子,就搞定了:) 所以技术难点只有三个:获得雷区数据、找到扫雷程序和模拟鼠标动作。
