Clustering algorithm -- k-means algorithm

Learning objectives: clustering algorithm Learning content: k-means algorithm Learning records: Clustering algorithms mainly include: (1) Partition clustering. Most of them are distance based clustering algorithms. There are k-means,k-medoids,CLARANS (2) Hierarchical clustering. It is to decompose hierarchically until certain con ...

C + + uses opencv to call cascade classifier to identify target objects

Using compiler: Qt Creator 4.2.1 preface: Compared with the frame difference method to capture the target object recognition, the cascade classifier recognition of the target object is more targeted. Using the former, as long as the moving object will be captured and recognized, and if there is a little trouble in the picture, it will be capt ...

Principle derivation of K-means algorithm

Summary: This paper will introduce a common algorithm of machine learning: k-means clustering. Clustering belongs to unsupervised learning. Compared with classification, clustering does not rely on predefined classes and training examples of class labels. Because k-means clustering is relatively simple, I mainly intro ...

The isolated forest algorithm for anomaly detection is explained in detail with code running examples

Because the abnormal value often has two characteristics: only a small amount of abnormal data, and the characteristic value of abnormal data is very different from normal data. Isolated forest is not to describe normal sample points, but to isolate outliers, which was proposed by Professor Zhou Zhihua and others at the 8th IEEE International C ...
