DOCOMO Unveils AI Model to Solve Cold-Start Forecasting Gaps
Tokyo – October 12, 2026 -- NTT DOCOMO, INC. has developed an AI model that delivers accurate predictions from the first day of a new service, and it will test the technology in field trials with digital out-of-home (DOOH) advertising businesses in Japan and overseas by March 2027.
The Dual-view Adaptive Retrieval-augmented Tweedie model targets the "cold-start problem." This occurs when AI cannot make reliable predictions or recommendations because historical data is insufficient, for example after a service launch or an expansion into a new field or region. A paper on the model has been accepted for presentation at the 20th ACM Conference on Recommender Systems (ACM RecSys 2026).
