Briefings

A new ProactiveCoach suite addresses limitations in AI guidance by introducing hierarchical procedural understanding. The system uses hierarchical supervision to improve performance by up to 9.6% compared to fixed-granularity methods, while an adaptive guidance router achieves a 57.1% improvement over in-context adaptation without further fine-tuning. The project is available at https://jinsuby.github.io/ProactiveCoach/.

Key points

• The ProactiveCoach suite introduces hierarchical procedural understanding to improve AI guidance adaptability.
• Hierarchical supervision improves overall performance by up to 9.6% compared to fixed-granularity supervision.

Context

Existing datasets focus on detection-based understanding or use fixed-granularity guidance, limiting progress tracking. This research introduces hierarchical guidance at phase, step, and action levels to better capture task progress and procedural context.

Limitations

Evidence covers training, evaluation, and fine-tuned VLMs with an adaptive guidance system. Performance gains are demonstrated across backbones but specific model names or hardware details are not provided. The adaptive guidance router's effectiveness is shown without additional fine-tuning, but the underlying router architecture is not described.
