无监督学习(Unsupervised Learning)的职责在于发现数据中的隐含结构,而其中的数据样本未给定对应的目标值(unlabeled data)。如果我们要将相似的样本划分为不同的组,这类问题称之为聚类(Clustering);如果我们需要找出输入空间的数据分布状况,这类问题称之为密度估计(Density Estimation);我们也可以利用主成份分析(Principal ...
Deep Learning (Deep Learning Algorithms).Deep learning algorithms are a subfield of machine learning that requires larger data sets, takes a longer time to train, lowers the need for human intervention, and trains on graphic cards(GPUs). Deep learning algorithms can analyze data through supervised ...
Soft clustering, where each data point can belong to more than one cluster This video uses examples to illustrate hard and soft clustering algorithms, and it shows why you’d want to use unsupervised machine learning to reduce the number of features in your dataset. ...
2.1. Types of Unsupervised Machine Learning There are three main types of Unsupervised Machine Learning: Clustering:Clustering is an unsupervised learning technique that groups data points according to their properties or similarities. The primary objective here is to recognize the relationship and similari...
