UnverifiedCompared with traditional end-to-end imitation learning, VLA models have stronger generalization capabilities, but high inference latency, stringent requirements for training data diversity, and deployment on real-time control and low-cost hardware remain the primary challenges.79% similarUnverifiedEffectively combining hardware-aware training and adaptation mechanisms with large-scale VLA pretraining remains an open problem.74% similarUnverifiedVLA models unify visual perception, language understanding, and action generation within a single model framework, and their training is highly dependent on large-scale, high-quality human manipulation demonstration data.73% similarUnverifiedPerformance bottlenecks in VLMs, beyond the visual encoder, may also stem from the connector/projector module, the language model's instruction-following capability, and training data.72% similarUnverified微调VLA模型时通常采用分层学习率策略：视觉编码器使用极小学习率或冻结，语言模型层使用中等学习率，动作专家使用较大学习率71% similar
