Reference open-data run
DeepSubDAS high-noise HDF5 example
This page documents one reproducible demonstration run using a recognized open DAS research dataset. The input is an HDF5 DAS array window, which is the strongest public example currently included with the demo. The numbers below are for this input window and run only; they are not a universal performance claim.
Dataset Credit
Example input: a 33.6 MB HDF5 window from the Zenodo record DeepSubDAS: An Earthquake Phase Picker from Submarine Distributed Acoustic Sensing Data, DOI 10.5281/zenodo.16014744.
The Zenodo record lists the dataset under CC BY 4.0 and notes that a newer record version exists. This demo is not endorsed by the dataset authors.

Run Verification
A controlled browser workflow was tested on April 29, 2026: page load, upload, server processing, result rendering, result downloads, cleanup, and a public-output scan for server/IP or proprietary method terms. The values below document that run and should be read as one reproducible example, not a universal performance claim.
| Check | Observed Result |
|---|---|
| Input shape | 300 channels x 4000 samples at 100 Hz |
| Input family | HDF5 DAS channel-by-time array with embedded event labels |
| CPU regression runtime | 8.3 seconds for the regenerated public-safe reference package on the local validation machine |
| Status | Enhanced |
| Downloads | Processed HDF5, portable HDF5, PDF report, PNG preview, result summary, metrics JSON, interactive preview |
| Output safety | Public-safe metadata, generic channel labels, no source path, no server address, and no proprietary method details in returned files |
Result Interpretation
| Metric | Value | Interpretation |
|---|---|---|
| Median SNR gain | +11.02 dB, 95% CI 10.68 to 11.54 dB | Event-window energy became substantially clearer relative to measured quiet-window noise. |
| Raw median SNR | 5.88 dB | Baseline quality before the HADRON run on this file. |
| HADRON median SNR | 16.47 dB | Measured quality after the HADRON run on the same event windows. |
| Signal/noise AUC | 0.9737 to 1.0000, delta +0.0263 | Separation between labeled event and quiet windows improved, but raw AUC was already high and the comparison is ceiling-limited. |
| Waveform match | 0.9957 | Timing and event-window morphology were preserved closely enough for review. |
Metric provenance: the quality metrics use labeled signal/noise windows available in the reference data. They measure windowed signal-quality improvement for this input/run; they are not independent phase-picking, event detection, relocation, or full spatial seismological validation.
The run also reports that channel spacing metadata was unavailable. The result supports windowed signal-quality improvement, but missing spacing limits spatial-array interpretation, apparent velocity, location, and phase-interpretation claims.
Visual Result
The preview uses matched color scaling before and after processing, so the reader can inspect the change without hidden display scaling. The shown preview is selected from a strongly improved channel and should be read together with the metrics and PDF report.
