Evaluating the Interpretability of Sparse Autoencoders with Concept Annotations

Jonas Klotz, C. Fraga Dantas, P. Jain, D. Marcos, B. Demir

ECCV · 2026

We present a human-grounded framework for evaluating sparse autoencoders using concept annotations and targeted image perturbations. We introduce FBMP for coalition-based matching, synCUB/synCOCO benchmarks, and TAPAScore for causal validation.

Equal contribution

IEEE JSTARS · 2026

Federated learning for remote sensing suffers from high communication costs. We propose explanation-guided model pruning to reduce bandwidth while preserving accuracy.

On the Effectiveness of Methods and Metrics for Explainable AI in Remote Sensing Image Scene Classification

Jonas Klotz, T. Burgert, B. Demir

IEEE JSTARS · 2025

We systematically evaluate XAI methods and their evaluation metrics for scene classification in remote sensing, revealing critical gaps between method capability and metric design.

Communication-Efficient Federated Learning Based on Explanation-Guided Pruning for Remote Sensing Image Classification

Jonas Klotz, B. Büyüktaş, B. Demir

IGARSS · 2025

Using gradient-based explanations to identify and prune redundant parameters, we reduce federated communication overhead for remote sensing classifiers without accuracy loss.

A Label Propagation Strategy for CutMix in Multi-Label Remote Sensing Image Classification

T. Burgert, K. N. Clasen, Jonas Klotz, T. Siebert, B. Demir

IEEE JSTARS · 2025

We introduce a label-aware mixing strategy that improves multi-label classification robustness in satellite imagery by propagating soft labels through augmented training pairs.
