Data Format

The dataset has been split into train, val, and test jsonl files. Each line of each jsonl file has the following fields:

• object_id: unique identifier for the object
• times_wv: an array of shape (T, 2), where the i-th element contains (t_i, w_i), the time and wavelength of the i-th measured flux value. If t_i = 0, then this is a padded value and the associated flux f_i will also be 0.
• lightcurve: an array of shape (T, 2), where the i-th element contains (f_i, f_err_i), the i-th flux and uncertainty on that flux measurement (flux error).
• label: an integer label corresponding to an astronomical object type. This is the value to be predicted.

Usage

The directory includes a custom dataset loading script (raw_train_with_labels.py), which will be used when calling

load_dataset("/path/to/current/dir")
