MoGA: Mixture-of-Groups Attention for End-to-End Long Video Generation

ICLR 2026poster

Long video generation with Diffusion Transformers (DiTs) is bottlenecked by the quadratic scaling of full attention with sequence length. Since attention is highly redundant, outputs are dominated by a small subset of query–key pairs. Existing sparse methods rely on blockwise coarse estimation, whos…

Swashplateless-Elevon Actuation for a Dual-Rotor Tail-Sitter VTOL UAV

IROS 2023poster

In this paper, we propose a novel swashplateless-elevon actuation (SEA) for dual-rotor tail-sitter vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAVs). In contrast to the conventional elevon actuation (CEA) which controls both pitch and yaw using elevons, the SEA adopts swash-platele…
