Text-to-OverpassQL: A Natural Language Interface for Complex Geodata Querying of OpenStreetMap

1 code implementation30 Aug 2023 Michael Staniek, Raphael Schumann, Maike Züfle, Stefan Riezler

We present Text-to-OverpassQL, a task designed to facilitate a natural language interface for querying geodata from OpenStreetMap (OSM).

VELMA: Verbalization Embodiment of LLM Agents for Vision and Language Navigation in Street View

1 code implementation12 Jul 2023 Raphael Schumann, Wanrong Zhu, Weixi Feng, Tsu-Jui Fu, Stefan Riezler, William Yang Wang

In this work, we propose VELMA, an embodied LLM agent that uses a verbalization of the trajectory and of visual environment observations as contextual prompt for the next action.

Backward Compatibility During Data Updates by Weight Interpolation

no code implementations25 Jan 2023 Raphael Schumann, Elman Mansimov, Yi-An Lai, Nikolaos Pappas, Xibin Gao, Yi Zhang

This method interpolates between the weights of the old and new model and we show in extensive experiments that it reduces negative flips without sacrificing the improved accuracy of the new model.
