The Particle Filter: A Full Tutorial

The Particle Filter is one of my FAVOURITE algorithms. It's so simple to understand and to implement, yet the performance is quite robust! The central idea behind the particle filter is to brute force your way to the solution. Start with a bunch of particles that represent where you think you are right now. Then, for the prediction step, propagate each particle through the motion model. Following in the correction step, if a particle is unlikely to produce the measurement we obtain, just get rid of it! Repeat. See? It just took a few sentences to explain. Hope you enjoy!

Hi James! Thank you so much for sharing this video. It is beneficial to my research. I'm wondering would you mind to also talk about the Practical Filter?

Hi Frank! You're welcome! Unfortunately I'm not familiar with the Practical Filter, so I'm unable to help you... Good luck with your research!

video is awesome, but the music in the background is totally unnecessary ://
