Fine-Tuning Vision-Language-Action Models: Optimizing Speed and Success
RoboticsRecent vision-language-action models (VLAs) build upon pretrained vision-language models and leverage diverse robot datasets to demonstrate strong task execution, language following ability, and semantic generalization.

Group Actions and Representations
2015To facilitate the study of abstract objects, a central theme in mathematics is their representations as more concrete ones while preserving their fundamental properties. This procedure is evidently useful if the representing objects have additional special structure, which then allows to carry out concrete calculations in specific situations, or to ...

Action without Representations
2017This chapter develops a critique of representationalist accounts of action. It shows that on any standard definition of representation, concepts such as minimal or action-oriented representations (AORs) are not really representational in any meaningful sense.

A unified video and action model holds significant promise for robotics, where videos provide rich scene information for action prediction, and actions provide dynamics information for video prediction. However, effectively combining video generation and

Representational Foundations of Intentional Action
2005Abstract We speak of intentions from both a first- and a third-person perspective. From the external, third-person perspective, we speak of somebody (or perhaps an animal) entertaining a certain intention (1) when we believe that she is pursuing a certain goal, and (2) when we perceive him/her trying to perform certain actions suited ...

Royal Institute of Philosophy Supplement, 2017
AbstractFrom its inception, the philosophy of action has sought to account for action in terms of an associated kind of explanation. The alternative to this approach was noticed, but not adopted, by G.E.M. Anscombe. Anscombe observed that a series of answers to the reason-requesting question ‘Why?’ may be read in reverse order as a series of answers to

Actions on Parametric Representations
1998Now with the use of parametric representations, we come to the basic idea of this work, namely we can define the arbitrary nonlinear Lie group actions on functions $$ G\;x\;C_{_n}^\infty \left( M \right) \to C_{_n}^\infty \left( M \right) $$ (4.1) in the following simple and natural way.
