How Particle Filters Behave

In the online artificial intelligence class I'm taking from Youtube, a video mentions particle filters and how they work.

Initially the particles are randomly and evenly distributed across the whole space, kinda like senators. Then as more information is gathered the particles are redistributed based on which areas have the important information and which areas don't. In fact the areas without the important information might have no particles when the particle filter is completely done figuring everything out.

Back to the areas with important information, they have a greater say in where the next round of particles go until finally the areas with the most particles and the most weight or importance match. So house representatives' distribution in the U.S. is kinda like the particles, except every representative has the same weight in the U.S. legislative branch.
