Implementation Of K-means Method, Elbow Method, Silhouette Analysis

This article describes how the k-means method works and how it is implemented. In addition, the k-means method requires that the number of clusters to be classified be given in advance, and the elbow method and silhouette analysis are introduced as methods for determining the optimal number of clusters.

【Google Colab】How to do object detection and learning with YOLO v5

In this article, we will use Python to perform object detection. Object detection is a technique for detecting what is in an image and where it is in the image. In this article, we will run "YOLO v5" on Google Colab, which makes it easy to try such object detection.

Theory of Support Vector Machines (SVM)

The theory of Hard Margin Support Vector Machines (SVMs) is explained in an easy-to-understand manner.SVMs are a type of supervised machine learning algorithm for pattern identification. It is an excellent two-class classification algorithm with the idea of "maximizing margins."
