The Machine Learning Advent Calendar Day 3: GNB, LDA and QDA in Excel

The article highlights the implementation of fundamental machine learning classifiersGaussian Naive Bayes (GNB), Linear Discriminant Analysis (LDA), and Quadratic Discriminant Analysis (QDA)within Microsoft Excel, making these advanced algorithms accessible without specialized software. This development enables users to perform probabilistic classification tasks by translating local distance metrics into global probability estimates directly in a familiar spreadsheet environment, thereby broadening the practical application of machine learning techniques for data analysis and decision-making.
