Implementation of Multiple Classification Algorithms for Three Datasets (Including Iris Test Data)

In this document, we explore three distinct classification algorithms (LMS, MSE, and HK) for classifying three different datasets, including the renowned Iris test dataset. We provide comprehensive explanations of each algorithm's working principles along with practical Python implementations. Key implementation details include: gradient descent optimization for LMS (Least Mean Squares) weight updates, error calculation methods for MSE (Mean Squared Error) evaluation, and specialized techniques for HK algorithm implementation. We conduct comparative analysis of algorithm performance across different dataset characteristics and discuss parameter tuning strategies. Additionally, we offer practical tips for adapting these algorithms to handle other datasets effectively, covering data preprocessing, feature scaling, and model validation techniques using scikit-learn's train_test_split function. The code examples demonstrate proper use of NumPy for matrix operations and matplotlib for visualization of classification boundaries.
