Thanks, yes, lot of good ideas in ML seem to be slowly vanishing from the collective awareness. I have nothing against the current spate of methodologies which are empirically great - and if one needs proof, I am a "happy customer" at my day job which is mostly DL and a lot of LLMs - but it seems we are buying into a world where it is one versus the other. And this it need not be. Great ideas are great ideas irrespective of age and there is value in preserving them.
Anyway, since this thread surprisingly evoked a mini-discussion on Dirichlet Processes (DP), if someone needs an intro, I have tried to balance math and intuition in a description in my thesis: Section 2.2 in [1].

EDIT: I looked at the description and I confess it still has a lot of math (since it is part of thesis). I will probably translate this to be more friendly and put it on my blog.
