Introduction Large language models are trained on huge datasets of text to learn the relationships and contexts of words within larger documents. These relationships are what allows the model to generate text. Recently I've read concerns about LLMs being trained on copyrighted text and reproducing it. This got me…

Choosing what to read
Like many people, I spend a lot of time reading. Since there is much more that I could read than there is time for, I have to make choices about what I should read.
