Deep Learning Detection of Beyond-General-Relativity Deviations in Gravitational-Wave Signals: A Detection-Threshold Study with Real LIGO Noise

The paper investigates machine‑learning detection of controlled deviations from General Relativity in gravitational‑wave signals. Using a hybrid classifier that combines a one‑dimensional convolutional neural network with ten hand‑crafted waveform statistics, the authors train on General‑Relativistic and modified waveforms and test on a deviation type not seen during training. They find a detection threshold at a dimensionless strength coefficient β ≈ 0.25 when using real GW150914 strain and real H1 detector noise, with accuracy improving from chance at β ≤ 0.2 to perfect classification at β ≥ 0.5.

Improving the Sensitivity of Gravitational Wave Detection with Weighted Conformal Prediction

The paper proposes a weighted conformal prediction framework to combine outputs from multiple gravitational‑wave search pipelines, providing statistically rigorous confidence estimates for candidate events. By incorporating likelihood‑ratio reweighting, the method corrects for covariate shift between simulated training data and real observations, restoring well‑calibrated coverage. Experiments on mock datasets show that this approach improves sensitivity, especially near the detection threshold, enabling recovery of true signals that would otherwise be missed.

Auditing Frozen-Encoder Anomaly Detection Across Mechanical Systems: Representation Provenance, Calibration, and Protocol Effects

This paper presents a reproducibility audit of frozen‑encoder anomaly detection experiments originally reported on arXiv. The authors confirm that the numerical discrimination results can be reproduced from the preserved artifacts, but they find that the claimed causal link to interferometric pretraining is unsupported. They show that near‑zero embeddings and architectural choices, rather than a morphological prior from gravitational‑wave instrumentation, explain the observed anomaly‑detection performance.

Decoupling candidate dual AGN from chance superpositions in the GOTHIC survey via a deep-learning framework

The study presents a deep‑learning approach (YOLOv11) trained on SDSS images to distinguish genuine dual active galactic nuclei (DAGN) from chance superpositions and foreground stars in the GOTHIC survey. Applying the model to 46,061 previously rejected candidates yields 29,605 dual‑nucleus candidates, with 54.5–62 % likely genuine, and a conservative subset of ~13,672 compact systems. The resulting catalogue refines the DAGN candidate list, reducing contamination and expanding the plausible census, though spectroscopic confirmation remains needed.

Two kinds of robustness are not the same: disentangling fault tolerance and low-SNR robustness in multi-domain event detection on real data

Reliable event detection underpins induced-seismicity monitoring for Carbon dioxide Capture and Storage (CCS) and geothermal operations, distributed acoustic sensing (DAS), and industrial condition monitoring. In each setting a detector must stay reliable both when sensors fail and when the signal is buried in noise.
