Alpamayo-R1: Making Autonomous Driving Safer in Rare Scenarios
17 days ago 高效码农How Alpamayo-R1 Makes Autonomous Driving Safer in Long-Tail Scenarios Autonomous driving systems have made remarkable progress in highway cruising and urban following, yet they remain vulnerable in rare, safety-critical “long-tail” events—sudden pedestrian crossings, construction zones, or unexpected vehicle cut-ins. Traditional end-to-end models trained through imitation learning struggle here because supervision is sparse and causal understanding is limited. When a vehicle encounters a construction zone with workers stepping into the road, a conventional model might fail to recognize the need for evasive action due to insufficient training examples. To address this gap, researchers introduce Alpamayo-R1 (AR1), a vision-language-action model that integrates …
