Web1. júl 2024 · The redshift prediction is a regression task, i.e. target values z i are real numbers. To properly train, validate, and test a model, we split a given data set into a training, validation, and test sets. Usually, we iteratively show the training set to the model during training to train its model parameters Θ.

The degrader expects a pandas DataFrame, so we will create three dataframes for each of a low, mid, and hi redshift sample. Let's also add a weight column to the test data while we are at it, this will be used later by the NZDir algorithm (for now we'll set all weights to one):
