  1. What exactly is the alpha in the Dirichlet distribution?

    Nov 9, 2016 · The Dirichlet distribution is a distribution over the simplex, hence a distribution over finite support distributions. If you aim at a distribution over continuous distributions, you should …

  2. Dirichlet distribution vs Multinomial distribution? - Cross Validated

    May 21, 2020 · Dirichlet is commonly used as a prior on a probability vector, since it is the conjugate prior of the multinomial distribution.

  3. probability - What is a Dirichlet prior - Cross Validated

    Dec 25, 2014 · You can watch the whole presentation if you want (it is a good explanation of the Dirichlet distribution) but I think the slides will get the concept across pretty quickly. Slides 32 …

  4. Dirichlet conditions for the convergence of Fourier series

    May 9, 2017 · According to Wikipedia, Dirichlet conditions are f f must be absolutely integrable over a period. f f must have a finite number of extrema in any given bounded interval, i.e. there …

  5. bayesian - Why is the Dirichlet distribution the prior for the ...

    The Dirichlet distribution is a conjugate prior for the multinomial distribution. This means that if the prior distribution of the multinomial parameters is Dirichlet then the posterior distribution is also …

  9. Understanding and Implementing a Dirichlet Process model

    Aug 16, 2015 · 14 I am trying to implement and learn a Dirichlet Process to cluster my data (or as machine learning people speak, estimate the density). I read a lot of paper in the topic and sort …
