Five Particle Filter Simulation Algorithms

Resource Overview

Implementation and analysis of five particle filter variants, designed to help beginners understand core algorithms through practical simulation examples with code explanations

Detailed Documentation

This article presents five distinct particle filter simulation implementations that enable beginners to comprehensively understand particle filtering algorithms and build foundational knowledge for exploring more complex applications. The five simulations include: resampling-based particle filters, importance sampling-based particle filters, Extended Kalman Filter (EKF) integrated particle filters, Unscented Kalman Filter (UKF) hybrid particle filters, and Kalman filter-guided particle filters. Each implementation will be explained with corresponding algorithm workflows, MATLAB/Python code snippets highlighting key functions like systematic_resampling() or importance_weight_calculation(), and practical comparisons of their advantages/disadvantages in real-world scenarios such as target tracking or sensor fusion applications.
