K-nearest neighbor (KNN) is one of the most popular algorithms in machine learning, widely used in both supervised and unsupervised learning. In supervised learning, KNN is used to calculate the distance to k neighbors and can define outliers. In unsupervised learning, KNN is also used to calculate the distances to neighbors and then define outliers. … Read more

This series of tutorials serves as notes for the book “Hands-On Machine Learning.” First, let’s discuss the reasons for writing this series: First, the code in “Hands-On Machine Learning” is written in Python 2, and some of the code will throw errors when run on Python 3. This tutorial revises the code based on Python … Read more
KNN Practical Application – Improving Matchmaking Effectiveness Introduction In simple terms, the KNN algorithm classifies data by measuring the distances between different feature values. The working principle is that there exists a sample dataset, namely the training dataset, and each sample in the dataset has a label, which indicates the correspondence between each data point … Read more
Today is the seventh issue summarizing 16 major topics and 124 interview questions in machine learning: K-Nearest Neighbors (KNN) algorithm interview questions. The K-Nearest Neighbors (KNN) algorithm works by finding the K nearest neighbors of a sample and using the information from these K neighbors to make predictions. For classification tasks, the majority voting method … Read more
