Active Label Refinement for Semantic Segmentation of Satellite Images

no code implementations12 Sep 2023 Tuan Pham Minh, Jayan Wijesingha, Daniel Kottke, Marek Herde, Denis Huseljic, Bernhard Sick, Michael Wachendorf, Thomas Esch

Since these initial labels are partially erroneous, we use active learning strategies to cost-efficiently refine the labels in the second step.

Probabilistic Active Learning for Active Class Selection

no code implementations9 Aug 2021 Daniel Kottke, Georg Krempl, Marianne Stecklina, Cornelius Styp von Rekowski, Tim Sabsch, Tuan Pham Minh, Matthias Deliano, Myra Spiliopoulou, Bernhard Sick

In machine learning, active class selection (ACS) algorithms aim to actively select a class and ask the oracle to provide an instance for that class to optimize a classifier's performance while minimizing the number of requests.

Efficient SVDD Sampling with Approximation Guarantees for the Decision Boundary

2 code implementations29 Sep 2020 Adrian Englhardt, Holger Trittenbach, Daniel Kottke, Bernhard Sick, Klemens Böhm

Our approach is to frame SVDD sampling as an optimization problem, where constraints guarantee that sampling indeed approximates the original decision boundary.

Toward Optimal Probabilistic Active Learning Using a Bayesian Approach

1 code implementation2 Jun 2020 Daniel Kottke, Marek Herde, Christoph Sandrock, Denis Huseljic, Georg Krempl, Bernhard Sick

Gathering labeled data to train well-performing machine learning models is one of the critical challenges in many applications.

Limitations of Assessing Active Learning Performance at Runtime

no code implementations29 Jan 2019 Daniel Kottke, Jim Schellinger, Denis Huseljic, Bernhard Sick

Hence, it is not possible to reliably estimate the performance of the classification system during learning and it is difficult to decide when the system fulfills the quality requirements (stopping criteria).
