Robust Jumping with an Articulated Soft Quadruped via Trajectory Optimization and Iterative Learning

Ding, J. (author), Sels, Mees A.van Loben (author), Angelini, Franco (author), Kober, J. (author), Della Santina, C. (author)

Quadrupeds deployed in real-world scenarios need to be robust to unmodelled dynamic effects. In this work, we aim to increase the robustness of quadrupedal periodic forward jumping (i.e., pronking) by unifying cutting-edge model-based trajectory optimization and iterative learning control. Using a reduced-order soft anchor model, the...

Zhou, Z. (author), Ge, Jianzhong (author), van Maren, D.S. (author), Gu, Jinghua (author), Ding, Pingxing (author), Wang, Zhengbing (author)

The Krone–Partheniades (K-P) framework has been used for decades to quantify and analyze the sediment exchange at a water–bed interface. Measuring the erosion and deposition parameters that are part of this framework requires time-consuming field observations. Additionally, the erosion parameters are measured independently of deposition...

Design Guidelines for Inclusive Speaker Verification Evaluation Datasets

Hutiri, Wiebke (author), Gorce, Lauriane (author), Ding, Aaron Yi (author)

Speaker verification (SV) provides billions of voice-enabled devices with access control, and ensures the security of voice-driven technologies. As a type of biometrics, it is necessary that SV is unbiased, with consistent and reliable performance across speakers irrespective of their demographic, social and economic attributes. Current SV...
