Traj-VLN: Learning Pixel-Space Interaction via Autoregressive Trajectory Generation

This work proposes an alternative approach: fine-tuning VLMs to learn navigation interactions directly in 2D pixel space through autoregressive trajectory generation, and demonstrates that this flagship model achieves state-of-the-art level performance with relatively limited computational resources and training data.
