Researchers have developed a new framework called MoLaRx to address domain shift issues in Vision-Language Models (VLMs) used for trajectory planning. Unlike previous methods that treated domain shift uniformly, MoLaRx identifies that shift is structured across modalities (image vs. text) and layers within the VLM. The framework uses a Causal Importance Score to pinpoint these shift locations and then applies targeted repair techniques, such as Maximum Mean Discrepancy or Low Rank Adaptation, to specific layers. Evaluations on distinct VLM architectures and driving datasets demonstrated that MoLaRx significantly reduces trajectory errors while requiring fewer trainable parameters and lower inference latency compared to uniform adaptation methods.
