Neural Networks
Summary

The residual pathway in neural networks allows for optimization of one line of code at a time, with the gradients flowing uninterrupted along it. This allows for the learning of a short algorithm that can approximate the answer, with other layers contributing to refine it further.

Language Models
Summary

Large language models like GPT can predict the next word in a sequence by downloading massive amounts of text data from the internet and training the model to find emergent properties. Language models predict text and with a powerful enough neural net, they have the ability to scale up and predict text with surprising accuracy.
