SkillGate: Training In-Policy Skill Selection in Long-Horizon Agents
TL;DR
SkillGate introduces a novel approach for training agents to select skills in real-time during long-horizon tasks, significantly improving success rates. It enhances a 9B policy's trial success from 40.8% to 53.2% while reducing misleading skill exposure.
✦ Why It Matters
Implement SkillGate to enhance your agent's skill selection and improve performance in complex tasks.
Key Takeaways
- Adopt SkillGate for better skill selection in long-horizon tasks.
- Monitor trial success rates to evaluate agent performance improvements.
- Reduce misleading skill exposure by implementing distinct credit channels.
- Explore the impact of skill-naming tokens on agent decision-making.
How It Works
SkillGate partitions the feedback into two channels: outcome credit for execution tokens and action-local advantage for skill-naming tokens. This separation ensures that only the correct skill choice receives positive reinforcement, addressing the credit starvation issue.
