Training Dynamics of Contextual N-Grams in Language Models

1 code implementation1 Nov 2023 Lucia Quirke, Lovis Heindrich, Wes Gurnee, Neel Nanda

We show that this neuron exists within a broader contextual n-gram circuit: we find late layer neurons which recognize and continue n-grams common in German text, but which only activate if the German neuron is active.

Language Models Represent Space and Time

1 code implementation3 Oct 2023 Wes Gurnee, Max Tegmark

The capabilities of large language models (LLMs) have sparked debate over whether such systems just learn an enormous collection of superficial statistics or a set of more coherent and grounded representations that reflect the real world.

Finding Neurons in a Haystack: Case Studies with Sparse Probing

2 code implementations2 May 2023 Wes Gurnee, Neel Nanda, Matthew Pauly, Katherine Harvey, Dmitrii Troitskii, Dimitris Bertsimas

Despite rapid adoption and deployment of large language models (LLMs), the internal computations of these models remain opaque and poorly understood.

Learning Sparse Nonlinear Dynamics via Mixed-Integer Optimization

1 code implementation1 Jun 2022 Dimitris Bertsimas, Wes Gurnee

Discovering governing equations of complex dynamical systems directly from data is a central problem in scientific machine learning.
