Where they've grown or pulled back
FlatSponsored 1 conference in 2026, flat from 1 in 2025.
Counted per conference. 2026 is the latest year whose conferences have mostly happened. Tiers use the best tier each year; swatches show the path, oldest first. A conference counts as pulled out only when a later event published a complete sponsor list, since most events don’t say whether their list is complete.
Pulled out 1
Not sponsored since 2024 or earlier, though a later event published a complete sponsor list without them.
- ACML (Asian Conference on Machine Learning)last sponsored 2019; the conference ran again in 2021–25
Once or on and off 1
No clear direction, or a gap we can’t confirm because later sponsor lists are incomplete.
- VLDB (International Conference on Very Large Data Bases)once, 2020, Gold
