Transformers Explained Visually
“It isn't so much that "other setups didn't work". More like "the first thing we found that did work turned out to be the minimal thing that could work". Transformers are conventional feed-forward neural networks alternated with attention blocks. You can think of them as big huge…”

Transformers Explained Visually
“If I had to summarize this in with sentences then here is my attempt. Transformer training can be parallelized easily, making it possible to use brute force to train the neural network quickly (bitter lesson rewards compute friendly scalable architectures). Transformers have…”

Show HN: Thinc, a new deep learning library by the makers of spaCy and FastAPI
“I've been working on various versions of Thinc for a long time --- it's always been the name for the machine learning code powering spaCy. But previous versions really weren't worth using for other developers, and so I never wanted to advertise the library as something people…”

RasaGPT: First headless LLM chatbot built on top of Rasa, Langchain and FastAPI
“FWIW, individual classes are generally tiny, so we found using langchain is fine and then for places we need to beef up (chunking, not calling 'eval', ...), we do our own class/subclass. That way we can align with community for broader pieces and patterns, and decrease technical…”

Dead Code Should Be Buried – Why I Didn't Contribute to NLTK
“So rather than jump in and start adding documentation you blast the developers, who are offering this stuff free and without warranty or implied fitness for any purpose? You can contribute by adding documentation where you see it lacking, especially if you have domain specific…”

Dead Code Should Be Buried – Why I Didn't Contribute to NLTK
“I disagree strongly. This is the same difference as Linux vs Minix. Minix didn't want anything added as it was said to be for educational purposes even though that didn't reflect the use cases. The author points out that whilst the stated aim of NLTK is for education, it's used…”
