NVIDIA and Uber have revealed further details of their collaboration on autonomous vehicle technology. The partnership will leverage Uber's vast collection of real-world driving data to train NVIDIA's foundation models for self-driving systems. The goal is to enhance the realism and safety of autonomous driving by utilizing data from a wide variety of scenarios encountered by Uber vehicles. The collaboration utilizes NVIDIA's DGX Cloud infrastructure to refine the NVIDIA Cosmos World Foundation Models. This is aimed at creating high-fidelity simulations with fewer anomalies and improving model performance in rare or unusual driving situations. Following the announcement, which was detailed in a social media post by NVIDIA, Uber's stock (NYSE:UBER) saw a significant rise of 3.5%, indicating a positive investor reaction to the strategic initiative.
