要以2D 形式绘制集群,我们可以使用 ML-From-Scratch Github 存储库中的绘图函数。我们将绘制由我们的计算实现的集群,以及 Scikit-learn 返回的集群。 from mlfromscratch.utils import Plot p = Plot() p.plot_in_2d(X, y_preds, title="K-Means Clustering") p.plot_in_2d(X, y, title="Actual Cluste...
K-Means Clustering is one of the popular clustering algorithm. The goal of this algorithm is to find groups(clusters) in the given data. In this post we will implement K-Means algorithm using Python from scratch.
第 30 次迭代后,可以看到的模型在这个生成的数据集上表现良好。 这里只是为了解释GMM的概念进行的Python实现,在实际用例中请不要直接使用,请使用scikit-learn提供的GMM,因为它比我们这个手写的要快多了,具体的对象名是 sklearn.mixture.GaussianMixture,它的常用参数如下: tol:定义模型的停止标准。当下限平均增益低于...

Below, we describe episodes, state, action, and a reward function in our deep reinforcement learning algorithm using this 1D knapsack environment. Episode: We define an episode as the steps taken from a current state until we find an infeasible solution or the maximum number of steps per ...
This article explains K-means algorithm in an easy way. I’d like to start with an example to understand the objective of this powerful technique in machine learning before getting into the algorithm, which is quite simple.
