What Neural Language Models Can Actually Compute
The same hierarchy that classifies grammars can classify neural networks. This lesson places recurrent networks and transformers on the Chomsky ladder, explains why a transformer is theoretically weaker than it looks, and shows how formal language theory predicts where today's language models generalize and where they break.
Formal Grammars and the Chomsky Hierarchy
How much computational power does a language need? The Chomsky hierarchy answers it with four nested classes of grammar. This lesson builds the ladder from regular to recursively enumerable, shows the machine that recognizes each rung, and locates human language on it using the classic proof that it is not context-free.
