# PhyTS Dataset
|
| 5 |
+
## Abstract
|
| 6 |
+
We introduce PhyTS, a benchmark suite of precision scientific time series datasets for machine learning, spanning experiments in gravitational-wave detection, dark matter searches, neutrino mass determination, and stellar variability detection. Despite their diverse scientific goals, these domains share a common challenge: recovering weak, structured signals and estimating underlying physical parameters from noise-dominated measurements.
|
| 7 |
+
Unlike standard sequence modeling benchmarks such as audio and speech, these data exhibit non-Gaussian and nonstationary noise, long-range temporal correlations, detector-specific systematics, irregular sampling, and signals that are sparse, weak, or only partially modeled. As a result, they provide a challenging testbed for evaluating whether modern AI methods can support downstream scientific inference.
|
| 8 |
+
We provide standardized tasks, data splits, and evaluation protocols for denoising, signal recovery, and parameter inference across physics domains, along with baseline results. By unifying diverse weak-signal inference problems under a common framework, this benchmark aims to enable reproducible evaluation and accelerate the development of more robust, interpretable, and physically grounded methods for scientific time series analysis.

## TIDMAD
|
| 21 |
+
The TIDMAD dataset is broken into training and validation data which are identically constructed differing only by the time at which the detector data was taken.
|
| 22 |
+
This temporal difference results in variable detector noise conditions.
|
| 23 |
+
There are 20 hdf5 files (~ 4 GB/file) in both training and validation datasets.
|
| 24 |
+
The total dataset size is 163 GB.
|
| 25 |
+
Each file contains ~ 200 examples and the associated meta data.
|
| 26 |
+
Each example is a set of ch1 time series, ch2 time series, and injected frequency.
|
| 27 |
+
This data in each hdf5 file includes the following
