The Data Mining Society of INFORMS is organizing the 21st INFORMS Workshop on Data Mining and Decision Analytics (DMDA) on October 31, 2026, the day before the 2026 INFORMS Annual Meeting. You are cordially invited to attend the workshop and present your recent
research on data mining, decision analytics, and artificial intelligence. To participate in the workshop, a full paper must be submitted by the deadline of August 1, 2026, for consideration. All accepted papers are automatically considered for the DMDA Workshop
Best Paper Competition, either in the Theoretical Track or Applied Research Track, according to the presenters’ specifications. The winner and runners-up will be announced at the DMS business meeting and recommended for fast-track submission to the INFORMS
Journal on Data Science (IJDS).</div>
