Parallel robots have been widely applied because of their high stiffness and dynamic responsiveness. Advanced model-based control of such systems requires the accurate identification of dynamic parameters. This paper proposes a physically consistent dynamic parameter identification method enforced b
In this letter, we propose a one-finger nonprehensile manipulation strategy for repositioning and reorienting a 3D object in a frictional environment. The proposed manipulation strategy consists of the periodic searching and pushing modes of the robotic finger. In the searching mode, the finger star
Facial Attribute Manipulation (FAM) through GAN-based methods has been an active topic in computer graphics. Existing works show high editing fidelity on randomly generated faces but suffer from distortion on embedded real faces. We alleviate this issue by dividing it into two sub-problems. First, w…
Aspect-based sentiment analysis aims to identify sentiment polarity of social media users toward different aspects. Most recent methods adopt the aspect-centric latent tree to connect aspects and their corresponding opinion words, thinking that would facilitate establishing the relationship between…
Existing anomaly detection models show success in detecting abnormal images with generative adversarial networks on the insufficient annotation of anomalous samples. However, existing models cannot accurately identify the anomaly samples which are close to the normal samples. We assume that the main…
Stance detection aims to identify people’s standpoints expressed in the text towards a target, which can provide powerful information for various downstream tasks.Recent studies have proposed multi-task learning models that introduce sentiment information to boost stance detection.However, they negl…
In this paper, we present a design and control approach of a modular off-board actuation system with mono-articular hip exosuit, enabling the instantaneous assistive profile modification of magnitude, shape, and timing. The off-board system consists an actuation unit with two degrees of freedom that…
In this paper we describe an IMU-based iterative controller for hip extension assistance where the onset timing of assistance is based on an estimate of the maximum hip flexion angle. The controller was implemented on a mono-articular soft exosuit coupled to a lab-based multi-joint actuation platfor
This paper presents a trajectory tracking control strategy based on the subspace stabilization approach to accurately manipulate an under-actuated flying robot from a known initial state to the desired terminal state. To facilitate the development of this tracking strategy, the dynamical model of th…
