Re:A Minimal DDPM on Tuesday July 15, 2025 @11:21AM (#44572100)
Hello everyone! I'm writing a blog about my experience on training a minimal DDPM and just want to share what I've learned so far. Feel free to read and discuss with me.

Haha I feel so dumb now. Thank you!

Thank you for sharing this! I have one question: Is there any plan to add support for local LLM / embeddings models?

I think it cannot surpass SOTA in some LM evaluation sets, but please understand that achieving better results requires a very good training dataset, which not everyone can afford.

On the other hand, the main points of Zamba/Mamba are low latency, generation speed, and efficient memory usage. If this is true, LLMs could be much easier for everyone to use. All we need to do is wait for someone with a good training dataset to train a SOTA Mamba.

This is interesting.

How can you retrieve the latent representation of the candidate LLMs? Some models do not have open weights (such as GPT-4), which means AFAIK it is impossible to directly access the hidden latent space through their API.

Am I missing something?

Re:Ask HN: How LLMs Learn to Be "Generative"? on Sunday February 04, 2024 @11:25PM (#39257311)
Thank you. Can I ask a question?

Does this mean LLMs can generate text with empty context? How can LLMs choose the first token without any previous tokens? My understanding is that to compute logits for the next token, LLMs require input from all previous tokens. Am I correct?

Ask HN: How LLMs Learn to Be "Generative"?

AFAIK to be called "generative", a model should have the ability to learn the joint probability over the training data. In the case of LLMs, we apply the chain rule of Bayes' formula to achieve this by leveraging the autoregressive method for every token of each input text sequence. For example, with a text sequence of 4 tokens, it can be written as:p(x4,x3,x2,x1) = p(x4|x3,x2,x1) * p(x3|x2,x1)...

Thank you so much for sharing this great repo! I have noticed that the source transformation notebook is not finished yet. How is it now?

Well, I will choose shuffle mode if this service is available (((:
