Best Paper Award at APSIPA ASC 2026 in Bangkok

The 18th APSIPA Annual Summit and Conference (APSIPA ASC 2026) was held from November 9 to 12, 2026, at the Courtyard by Marriott Bangkok Suvarnabhumi Airport in Bangkok, Thailand. APSIPA ASC is the flagship annual conference of the Asia-Pacific Signal and Information Processing Association (APSIPA), bringing together researchers from across the region to present advances in signal processing, machine learning, and their applications, and is co-sponsored by the IEEE Signal Processing Society.

A paper from Tsukada Lab received the Best Paper Award at the conference. Muhammad Sulthan Adhipradhana (Adhi), now a first-year PhD student in Tsukada Lab, together with Ehsan Javanmardi, Naren Bao, and Manabu Tsukada, presented “DispatchRAG: Grounding Emergency Dispatch Decisions in Real-World Protocols from Traffic Accident Video.” The work proposes a retrieval-augmented framework that turns a dashcam accident clip into a protocol-grounded emergency-dispatch decision: a perception stage converts the clip into an observation-only scene description, a rule-retrieval agent rewrites the description into a query and fetches the applicable rules from a corpus of Japanese traffic-law and emergency-medical protocols, and a reasoning agent composes a three-perspective dispatch plan for the dispatching agency, the on-scene civilian, and the arriving EMS crew, with every directive citing the rule and the observed evidence that justify it. The work is based on Adhi’s master’s thesis research. Evaluated on a newly built Accident Dispatch Dataset of 500 annotated dashcam clips, the framework outperformed frontier vision-language-model baselines on structured decision metrics and produced the best-calibrated ambulance-dispatch decisions.

Congratulations to Adhi and the whole team on this achievement! Project page: https://adhipradhana.github.io/DispatchRAG/
