PACE: Perceived-Latency-Aware Cascading Service Routing and Filler Control for QoE-Efficient Retrieval-Augmented Dialogue Serving
TL;DR
PACE is a novel framework designed for retrieval-augmented dialogue systems that optimizes perceived latency in responses. It significantly reduces response times while maintaining quality, outperforming existing methods under high load conditions.
✦ Why It Matters
Implement PACE to enhance response times in your dialogue systems without sacrificing quality.
Key Takeaways
- Adopt PACE to optimize response times in dialogue systems.
- Utilize load-adaptive routing to manage high traffic efficiently.
- Implement filler control to minimize unnecessary service calls.
- Ensure cache admission strategies reduce stale responses effectively.
How It Works
PACE operates by dynamically selecting the best source for responses while managing the waiting period with filler content. The load-adaptive cascading router directs requests based on current system load, ensuring efficient resource use.
The joint path-filler controller fills the response gap with relevant information, minimizing user wait times. Volatility-aware cache admission assesses the freshness of cached responses, preventing outdated information from being served.
