Hello , I am from computer science and am preparing my PhD thesis in indoor geo location using the RSS(received signal strength) of wifi signals, am interested in estimating the received signals strength densities.
We used a probabilistic approach to model the RSS since the wifi signals are subject to reflexion and refraction in an indoor environment.
I found out that , the RSS of signals are not distributed according to a Gaussian, I heard that Dirichlet processes can estimate densities functions.
Can anyone advise me on a good introduction to Dirichlet processes and their applications .
