Understanding K-Nearest Neighbors: A Simple Approach to Classification and Regression

Towards AI

Photo by Avi Waxman on Unsplash What is KNN Definition K-Nearest Neighbors (KNN) is a supervised algorithm. The basic idea behind KNN is to find K nearest data points in the training space to the new data point and then classify the new data point based on the majority class among the k nearest data points.

Spatial Intelligence: Why GIS Practitioners Should Embrace Machine Learning- How to Get Started.

Towards AI

Created by the author with DALL E-3 Statistics, regression model, algorithm validation, Random Forest, K Nearest Neighbors and Naïve Bayes— what in God’s name do all these complicated concepts have to do with you as a simple GIS analyst? You just want to create and analyze simple maps not to learn algebra all over again.

From Good to Great: Elevating Model Performance through Hyperparameter Tuning

Towards AI

Examples of hyperparameters for algorithms Advantages and Disadvantages of hyperparameter tuning How to perform hyperparameter tuning?– For example, in the training of deep learning models, the weights and biases can be considered as model parameters. However, sometimes we do need to provide the initial values for them.

An Overview of Extreme Multilabel Classification (XML/XMLC)

Towards AI

In the second part, I will present and explain the four main categories of XML algorithms along with some of their limitations. However, typical algorithms do not produce a binary result but instead, provide a relevancy score for which labels are the most appropriate. Thus tail labels have an inflated score in the metric.

Anomaly detection in machine learning: Finding outliers for optimization of business functions

IBM Journey to AI blog

This type of machine learning is useful in known outlier detection but is not capable of discovering unknown anomalies or predicting future issues. Local outlier factor (LOF ): Local outlier factor is similar to KNN in that it is a density-based algorithm.
