From Keypoints to Predictive Distributions: Post-Hoc Uncertainty for YOLO-Pose Models
Alexej Klushyn, Juan Rivero Sesma, Florian Seligmann +3
The paper adds a lightweight post‑hoc module to trained YOLO‑Pose models that predicts calibrated predictive distributions for each keypoint, enabling uncertainty‑aware ranking and…
VLA-FAIL: Efficient Task Failure Detection for Finetuned Vision-Language-Action Models
Florian Seligmann, Emiliyan Gospodinov, Enes Ulas Dincer +1
Vision-language-action models (VLAs) achieve state-of-the-art performance on many robotic manipulation tasks, yet they can still behave unpredictably in out-of-distribution scenari…
SEAR: Sample Efficient Action Chunking Reinforcement Learning
C. F. Maximilian Nagy, Onur Celik, Emiliyan Gospodinov +4
Action chunking improves exploration and accelerates value propagation in long-horizon reinforcement learning, but naively applying off-policy methods to the temporally extended ac…
