Unveiling the Power of Transformer Architectures in Language Modeling

In this thrilling episode of AI Coffee Break with Letitia, the team delves into the mind-bending world of computational expressivity, where Parisit Al's groundbreaking work showcases how Transformer architectures can mimic the complexity of Turing machines. But hold on to your seats, folks, because it doesn't stop there! The discussion takes a wild turn as they uncover how Transformers and rnns, armed with Chain of Thought, can simulate probabilistic touring machines, becoming the ultimate language model powerhouses. Miss Coffee Bean brings in the brilliant mind of France Novak, a PhD student at eth, who unveils the secrets behind llm architectures' computational capabilities.

As France enlightens us on the Chomsky hierarchy and the significance of formal languages in natural language processing, we are taken on a riveting journey through the layers of complexity from regular to computable languages. The quest for Turing completeness in nn's becomes a focal point, shedding light on the intricate relationship between formal languages and the rich tapestry of natural language. The desire for nn's to reach the pinnacle of computational power echoes through the discussion, with an emphasis on the importance of modeling diverse linguistic phenomena.

Transformer encoders versus decoders emerge as key players in the Turing completeness game, with Transformer llms equipped with Chain of Thought emerging as the true touring equivalent champions. The dynamic capabilities of Transformer decoders, with their growing context window and iterative generation process, showcase a level of computational prowess that leaves traditional encoders in the dust. Rnns also step into the spotlight, revealing their surprising equivalence to touring machines under specific conditions, adding another layer of complexity to the already exhilarating discussion. The revelation that Transformer llms can simulate probabilistic touring machines, expressing distributions over strings, solidifies their position as the ultimate language model warriors in the ever-evolving landscape of computational linguistics.
