I would have expected the main target audience to be people NOT working in the AI space, that don’t have any prior knowledge (“from scratch”), just curious to learn how an LLM works. If you want to live in a world where this knowledge is open, at the very least refrain from publicly complaining about a book that cost roughly the same as a decent dinner. It’s much more accessible to regular developers, and doesn’t make assumptions about any kind of mathematics background. It’s a good starting poing after which other similar resources start to make more sense. I have to disagree on that being an obvious assumption for the meaning of “from scratch”, especially given that the book description says that readers only need to know Python.
This enables LLMs to better understand the nuances of natural language and the context in which it is used.
