(ML 7.7.A1) Dirichlet distribution

[@RobNeuhaus]

I'd love to have some like 30 second or 1 minute example application where you'd use the dirchlet distribution. I'd also like to know more about the gamma function, having never seen it before except in dense wikipedia pages. The recursive formulation looks close to but not quite a factorial, and it isn't just a function on the integers.

The Gamma is poppin in Bayes. Lots of conjugacy tricks with it.

Thank you sir. I'll be appreciated if you give some examples about Dirichlet distribution.

[@glaswasser]

so what exactly does alpha specify? It sounds a bit like a probability for something, but isn't that our theta?

[@JUEKUNLI]

Thanks a lot for your clear elaboration!!!

Is there a mistake in the comment or the video? In order to get the spiking on corners 1 and 3 of the triangle, that means you would need to set 0

nice tutorial! straight forward and simple!

[@gnomee9447]

That was very useful. Thank you!

nice explanation about dirichlet.very helpful thanks.

Hi, thanks! This video gives a great intuition for Dirichlet distributions. Say you have a prior Dirichlet distribution with all the alpha_i's less than one, so your prior is distributed around the corners of your simplex as you explain. Using Bayesian inference, when you feed the data in using this informed prior, does the posterior reflect a separation of the data into the corners as well? In other words, do you get a clustering of the data? Or am I way off base here? Thanks, Charles

It was very helpful. Thank you.

Dirichlet was German, I don't think the speaker is pronouncing his name correctly

On the other hand, "His paternal grandfather had come to Düren from Richelette (or more likely Richelle), a small community 5 km north east of Liège in Belgium, from which his surname "Lejeune Dirichlet" ("le jeune de Richelette", French for "the youth from Richelette") was derived."

He was born in what is today Germany, but was in his time part of the French Empire. The border marches between Germany and France are pretty tricky to categorize even today.
