With the continuous development of artificial intelligence technology, the distinction between Agentic AI and AI Agents has become a recurring topic. Companies are increasingly asking, “When should we utilize Agentic AI, and when is it better to choose AI Agents?” Although both forms of AI can yield transformative results, the key lies in understanding how … Read more
If you’ve been keeping up with artificial intelligence (AI) lately, you might have heard the terms AI agents and Agentic AI. While they sound like fancy technical jargon, they actually refer to two different types of AI that have significant impacts on our world. But what exactly are they? How do they differ? More importantly, … Read more

I previously wrote two articles on address processing, detailed below: Address Processing in Risk Control: Simple and Effective Regex Replacement Address Processing in Risk Control: Simple, Accurate, and Effective Multi-label Clustering Today we are writing the third article, using KNN to construct similar addresses. Although this article is about addresses, many scenarios can draw on … Read more

This article is reprinted from the public account Xinkou Dushuo KNN is a fundamental data classification algorithm in machine learning. Here, I will explain its utility through a story. Let’s start with a joke. During a matchmaking event, a beautiful girl asked the young man: Do you have a three-bedroom apartment? The young man: No. … Read more
K-Nearest Neighbors (KNN) The K-Nearest Neighbors (KNN) model is a simple and effective machine learning algorithm mainly used for classification and regression tasks. The basic idea of KNN is that the class or value of a sample depends on the classes or values of its k nearest neighbors. Specifically, KNN predicts the class or value … Read more
Hello everyone, I am Xiaohan. Today, I will share a powerful algorithm model, KNN. KNN (K-Nearest Neighbors) is an instance-based supervised learning algorithm widely used in classification and regression tasks. Its core idea is: given a sample, calculate its distance to all samples in the training set, find the K nearest samples (the nearest neighbors), … Read more
What is the K-Nearest Neighbors Algorithm (KNN)? The K-Nearest Neighbors algorithm (KNN) is a simple and intuitive machine learning algorithm widely used for classification and regression tasks. Its core idea is based on the principle of “birds of a feather flock together,” finding the K most similar neighbors by comparing the distance between a new … Read more
KNN (K-Nearest Neighbors) algorithm is a simple yet effective classification and regression algorithm. Its basic idea is to classify or predict by calculating the distance between samples. Below is an example of KNN algorithm implementation in Python, including data preparation, model training, and prediction. 1.
