Ruhr Hand Motion Catalog of Human Center-Out Transport Trajectories in 3D Task-Space Captured by a Redundant Measurement System

no code implementations31 Dec 2023 Tim Sziburis, Susanne Blex, Tobias Glasmachers, Ioannis Iossifidis

We introduce a systematic dataset of 3D center-out task-space trajectories of human hand transport movements in a natural setting.

Advancements in Upper Body Exoskeleton: Implementing Active Gravity Compensation with a Feedforward Controller

no code implementations9 Sep 2023 Muhammad Ayaz Hussain, Ioannis Iossifidis

In this study, we present a feedforward control system designed for active gravity compensation on an upper body exoskeleton.

Adaptive SpikeDeep-Classifier: Self-organizing and self-supervised machine learning algorithm for online spike sorting

no code implementations30 Mar 2023 Muhammad Saif-ur-Rehman, Omair Ali, Christian Klaes, Ioannis Iossifidis

The proposed algorithm is the first spike sorting algorithm that automatically learns the abrupt changes in the distribution of noise and SA.

ConTraNet: A single end-to-end hybrid network for EEG-based and EMG-based human machine interfaces

no code implementations21 Jun 2022 Omair Ali, Muhammad Saif-ur-Rehman, Tobias Glasmachers, Ioannis Iossifidis, Christian Klaes

Approach: In this work, we introduce a single hybrid model called ConTraNet, which is based on CNN and Transformer architectures that is equally useful for EEG-HMI and EMG-HMI paradigms.

From Motion to Muscle

no code implementations27 Jan 2022 Marie D. Schmidt, Tobias Glasmachers, Ioannis Iossifidis

Voluntary human motion is the product of muscle activity that results from upstream motion planning of the motor cortical areas.

Deep Transfer-Learning for patient specific model re-calibration: Application to sEMG-Classification

no code implementations30 Dec 2021 Stephan Johann Lehmler, Muhammad Saif-ur-Rehman, Tobias Glasmachers, Ioannis Iossifidis

In this study, we investigate the effectiveness of transfer learning using weight initialization for recalibration of two different pretrained deep learning models on a new subjects data, and compare their performance to subject-specific models.

Domain Adaptation Transfer Learning

Anchored-STFT and GNAA: An extension of STFT in conjunction with an adversarial data augmentation technique for the decoding of neural signals

no code implementations30 Nov 2020 Omair Ali, Muhammad Saif-ur-Rehman, Susanne Dyck, Tobias Glasmachers, Ioannis Iossifidis, Christian Klaes

GNAA is not only an augmentation method but is also used to harness adversarial inputs in EEG data, which not only improves the classification accuracy but also enhances the robustness of the classifier.
