Radar Spectra-Language Model for Automotive Scene Parsing

no code implementations4 Jun 2024 Mariia Pushkareva, Yuri Feldman, Csaba Domokos, Kilian Rambach, Dotan Di Castro

Finally, we explore the benefit of the learned representation for scene retrieval using radar spectra only, and obtain improvements in free space segmentation and object detection merely by injecting the spectra embedding into a baseline model.

Towards Autonomous Grading In The Real World

no code implementations13 Jun 2022 Yakov Miron, Chana Ross, Yuval Goldfracht, Chen Tessler, Dotan Di Castro

As the heuristics are capable of successfully solving the task in the simulated environment, we show they can be leveraged to guide a learning agent which can generalize and solve the task both in simulation and in a scaled prototype environment.

InsertionNet 2.0: Minimal Contact Multi-Step Insertion Using Multimodal Multiview Sensory Input

no code implementations2 Mar 2022 Oren Spector, Vladimir Tchuiev, Dotan Di Castro

We address the problem of devising the means for a robot to rapidly and safely learn insertion skills with just a few human interventions and without hand-crafted rewards or demonstrations.

Vision-Guided Forecasting -- Visual Context for Multi-Horizon Time Series Forecasting

no code implementations27 Jul 2021 Eitan Kosman, Dotan Di Castro

We examine the contribution of vision features, and find that a model fed with vision features achieves an error that is 56. 6% and 66. 9% of the error of a model that doesn't use those features, on the Udacity and Comma2k19 datasets respectively.
