[quirino]: I've been studying these a bunch for a project in university. Last week I went over the derivation of the ELBO for a couple hours and it was a very fun and elucidating exercise. Once you give names to the larger mathematical structures and understand them a bit better it becomes quite simple. I wish some of the blogs/papers I'd read had named "Importance Sampling". The probability notation can be pretty confusing too. Sometimes it's hard to understand the "t...

[radarsat1]: Something I've wondered, maybe I should just do it if I can find some time, but... given DeepSeek's nice results on using rendered text as input, I'm wondering if anyone has given serious research efforts towards image-based diffusion methods for text. As in, instead of all the complexities induced by discrete token generation, just generate the image of the text using standard image diffusion methods, then convert it to text. If you used a single, monospace font, I bet this wo...
[gdiamos]: I’d like to see more of these models. I’ve been using diffusion Gemma and it is very fast on GPUs in output token/sec. In the diffusion Gemma whitepaper, they say they could have done better with more time and compute. Even with those caveats, it is very uses-able as a local model.
[electroglyph]: good stuff, no mention of confidence tho, recommend having a look at diffusiongemma and others.
