title: Black carp (Mylopharyngodon piceus) mouth gape and size preference of a bivalve prey

description: These data represent the measurements of length and mouth gape from large juvenile and adult wild-caught and small juvenile hatchery origin black carp, and the results of laboratory size preference trials with bivalve prey, specifically Corbicula clams. Wild-caught black carp ranged from 429-1580 mm total length, a larger range than measured in previous studies. Corbicula feeding trial data consist of the shell dimensions of each clam, survival, and the frequency which clams were engulfed by black carp.

title: STEAD subsample 4 CDiffSD

description: # STEAD Subsample Dataset for CDiffSD Training

## OverviewThis dataset is a subsampled version of the STEAD dataset, specifically tailored for training our CDiffSD model (Cold Diffusion for Seismic Denoising). It consists of four CSV files, each saved in a format that requires Python's `pd.read_pickle` method for opening.

## Dataset FilesThe dataset includes the following files:



df_train: Used for both training and validation phases (with validation train split). Contains earthquake ground truth traces.

df_noise_train: Used for both training and validation phases. Contains noise used to contaminate the traces.

df_test: Used for the testing phase, structured similarly to df_train.

df_noise_test: Used for the testing phase, contains noise data for testing.


Each file is structured to support the training and evaluation of seismic denoising models.

## Data ColumnsThe dataset files contain columns from the original STEAD dataset, with specific focus on the following columns that are critical for our use:



E_channel: East-West channel data

N_channel: North-South channel data

Z_channel: Vertical channel data

s_arrival_sample: Sample index for S-wave arrival

p_arrival_sample: Sample index for P-wave arrival

trace_name: Identifier for the seismic trace


## UsageTo load these files in a Python environment, use the following approach:

```pythonimport pandas as pd

# Example of loading the training datadf_train = pd.read_pickle('path/to/df_train.csv')```

Ensure that the path to the file is correctly specified relative to your Python script.

## RequirementsTo use this dataset, ensure you have Python installed along with the Pandas library, which can be installed via pip if not already available:

```bashpip install pandas```
