A Large-scale Benchmark on Geological Fault Delineation Models: Domain Shift, Training Dynamics, Generalizability, Evaluation and Inferential Behavior

arXiv — cs.CV•Wednesday, November 12, 2025 at 5:00:00 AM

The recent large-scale benchmarking study on geological fault delineation models highlights significant challenges in the field of seismic interpretation, particularly regarding the generalizability of machine learning models. Conducted on over 200 combinations of model architectures and datasets, including FaultSeg3D, CRACKS, and Thebe, the study found that traditional fine-tuning practices often result in catastrophic forgetting, undermining model performance. In contrast, domain adaptation methods proved to be more effective when faced with substantial shifts in data distribution. This research is vital as it provides a systematic understanding of the limitations and potential of current models, paving the way for more reliable applications in geological exploration. The findings emphasize the need for consistent evaluation protocols and improved strategies to enhance the deployment of machine learning in real-world scenarios.

Adaptive Detection of Software Aging under Workload Shift

PositiveArtificial Intelligence

Software aging is a phenomenon that affects long-running systems, resulting in gradual performance degradation and an increased risk of failures. To address this issue, a new adaptive approach utilizing machine learning for software aging detection in dynamic workload environments has been proposed. This study compares static models with adaptive models, specifically the Drift Detection Method (DDM) and Adaptive Windowing (ADWIN). Experiments demonstrate that while static models experience significant performance drops with unseen workloads, the adaptive model with ADWIN maintains high accuracy, achieving an F1-Score above 0.93.

Fairness for the People, by the People: Minority Collective Action

PositiveArtificial Intelligence

Machine learning models often reflect biases found in their training data, resulting in unfair treatment of minority groups. While various bias mitigation techniques exist, they typically involve utility costs and require organizational support. This article introduces the concept of Algorithmic Collective Action, where end-users from minority groups can collaboratively relabel their data to promote fairness without changing the firm's training process. Three model-agnostic methods for effective relabeling are proposed and validated on real-world datasets, demonstrating that a minority subgroup can significantly reduce unfairness with minimal impact on prediction error.

Advanced Torrential Loss Function for Precipitation Forecasting

PositiveArtificial Intelligence

Accurate precipitation forecasting is increasingly crucial due to climate change. Recent machine learning approaches have emerged as alternatives to traditional methods like numerical weather prediction. However, many of these methods still use standard loss functions, which may not perform well during prolonged dry spells when precipitation is below the threshold. To overcome this issue, a new advanced torrential (AT) loss function is introduced, formulated as a quadratic unconstrained binary optimization (QUBO), which aims to enhance forecasting accuracy.
