2. Additionally, "em-" can connote "beyond, superior to," preceding adjectives to indicate that something or someone exceeds a certain standard in terms of power, quantity, or degree. For example, "eminent" means "distinguished or above average," and "empowered" means "having auth...
和EM算法一样,K-means每一步都最小化目标函数JJ,因而可以保证收敛到局部最优值,但在非凸目标函数的情况下不能保证收敛到全局最优值。另外,K-means对每个样本进行“硬分配(hard assignment)”,即只归类为一个簇,然而某些样本可能处于簇与簇的边界处,将这些样本强行分到其中一个簇可能并不能反映确信度。后文的...

(kmeans中,某样本点和模型中某个子成分,如果该样本点与子成分的中心距离最小,则以高斯的概率密度在中心点周围生成这个点,否则就不生成这个点。而GMM中,每个子成分都有可能生成该样本点,概率值为子成分的系数) 所以说GMM是更为flexible的model,由于大量的简化,使得k-means算法收敛速度快于GMM,并且通常使用k-means...
是未知的,称为隐变量,如无监督的学习问题,典型的如K-Means聚类算法,此时不能直接通过极大似然估计估计出模型中的参数。 二、EM算法简介 在上述存在隐变量的问题中,不能直接通过极大似然估计求出模型中的参数,EM算法是一种解决存在隐含变量优化问题的有效方法。EM算法是期望极大(Expectation Maximization)算法的简称,...

This means you can technically output in CommonJS to get ESM and CommonJS support. require()in ESM Sometimes it's useful to userequire()orrequire.resolve()in ESM. ESM code that usesrequire()can be seamlessly compiled to CommonJS, but when compiling to ESM, Node.js will error becauserequi...

Now the catch here is that these two units are not at all equivalent, what it means that if you set the height of an element to 50px then if you change the height to 50em, you will not get the same result. These two units are very different. Now, you must be wondering since ...
