Meanings and Feelings of Large Language Models: Observability of Latent States in Generative AI

no code implementations22 May 2024 Tian Yu Liu, Stefano Soatto, Matteo Marchi, Pratik Chaudhari, Paulo Tabuada

But if there are 'system prompts' not visible to the user, then the set of indistinguishable trajectories becomes non-trivial, and there can be multiple state trajectories that yield the same verbalized output.

Heat Death of Generative Models in Closed-Loop Learning

no code implementations2 Apr 2024 Matteo Marchi, Stefano Soatto, Pratik Chaudhari, Paulo Tabuada

The aim of this paper is to provide insights into this process (that we refer to as "generative closed-loop learning") by studying the learning dynamics of generative models that are fed back their own produced content in addition to their original training dataset.

Data-driven Stabilization of SISO Feedback Linearizable Systems

no code implementations30 Mar 2020 Lucas Fraile, Matteo Marchi, Paulo Tabuada

In this paper we propose a methodology for stabilizing single-input single-output feedback linearizable systems when no system model is known and no prior data is available to identify a model.
