Few-Shot Learning with Uncertainty-based Quadruplet Selection for Interference Classification in GNSS Data

no code implementations9 Feb 2024 Felix Ott, Lucas Heublein, Nisha Lakshmana Raichur, Tobias Feigl, Jonathan Hansen, Alexander Rügamer, Christopher Mutschler

Jamming devices pose a significant threat by disrupting signals from the global navigation satellite system (GNSS), compromising the robustness of accurate positioning.

Few-Shot Learning

Representation Learning for Tablet and Paper Domain Adaptation in Favor of Online Handwriting Recognition

no code implementations16 Jan 2023 Felix Ott, David Rügamer, Lucas Heublein, Bernd Bischl, Christopher Mutschler

The goal of domain adaptation (DA) is to mitigate this domain shift problem by searching for an optimal feature transformation to learn a domain-invariant representation.

Domain Adaptation for Time-Series Classification to Mitigate Covariate Shift

1 code implementation7 Apr 2022 Felix Ott, David Rügamer, Lucas Heublein, Bernd Bischl, Christopher Mutschler

To mitigate this domain shift problem, domain adaptation (DA) techniques search for an optimal transformation that converts the (current) input data from a source domain to a target domain to learn a domain-invariant representation that reduces domain discrepancy.

Auxiliary Cross-Modal Representation Learning with Triplet Loss Functions for Online Handwriting Recognition

no code implementations16 Feb 2022 Felix Ott, David Rügamer, Lucas Heublein, Bernd Bischl, Christopher Mutschler

We perform extensive evaluations on synthetic image and time-series data, and on data for offline handwriting recognition (HWR) and on online HWR from sensor-enhanced pens for classifying written words.

Benchmarking Online Sequence-to-Sequence and Character-based Handwriting Recognition from IMU-Enhanced Pens

no code implementations14 Feb 2022 Felix Ott, David Rügamer, Lucas Heublein, Tim Hamann, Jens Barth, Bernd Bischl, Christopher Mutschler

While there exist many offline HWR datasets, there is only little data available for the development of OnHWR methods on paper as it requires hardware-integrated pens.
