Time Series Classification for Detecting Parkinson's Disease from Wrist Motions

1 code implementation21 Apr 2023 Cedric Donié, Neha Das, Satoshi Endo, Sandra Hirche

We used a random search to find the highest-scoring InceptionTime architecture and compared it to ROCKET with a ridge classifier and a multi-layer perceptron (MLP) on wrist motions of PD patients.

Safe Learning-Based Control of Elastic Joint Robots via Control Barrier Functions

no code implementations1 Dec 2022 Armin Lederer, Azra Begzadić, Neha Das, Sandra Hirche

Ensuring safety is of paramount importance in physical human-robot interaction applications.

Multi-Modal Learning of Keypoint Predictive Models for Visual Object Manipulation

no code implementations8 Nov 2020 Sarah Bechtle, Neha Das, Franziska Meier

Our evaluation shows that our approach learns to consistently predict visual keypoints on objects in the manipulator's hand, and thus can easily facilitate learning an extended kinematic chain to include the object grasped in various configurations, from a few seconds of visual data.
