On February 17, Haomo.ai announced that the large-scale autonomous driving cognitive model was officially upgraded to “DriveGPT”, and will announce important progress at the 8th HAOMO AI DAY in April 2023.
As ChatGPT becomes popular all over the Internet, the Transformer large model and “Reinforced Learning with Human Feedback (RLHF)” technology it uses have once again attracted the attention of the industry. In the field of autonomous driving, Haomo.ai introduced the Transformer large model into the data intelligence system MANA.
On HAOMO AI DAY in January 2023, Gu Weihao, CEO of Haomo.ai, introduced that the human-driving self-supervised cognitive large model launched by Haomo.ai has borrowed from the implementation ideas of ChatGPT, adopted RLHF technology, and introduced real human drivers take over the data and continuously optimize the cognitive decision-making model for autonomous driving. Through this large model, in recognized difficult scenes such as U-turns and roundabouts, the pass rate of the scene has increased by more than 30%.
It is reported that at present, DriveGPT has completed the model building and the first-stage data running through, and the parameter scale can be compared with the level of GPT-2. Next, DriveGPT will continue to introduce large-scale real takeover data, and continuously improve the evaluation effect through intensive learning of human driving data feedback. At the same time, DriveGPT will also be used as a cloud evaluation model to evaluate the driving effect of the small car model.
