Data cleaning and preprocessing

The data was cleaned and preprocessed using the following script. Make sure to install depencies for beam_runner to make the dataset work.

from datasets import load_dataset
def load_and_clean_wiki():
    dataset = load_dataset('wiki40b', 'da', beam_runner='DirectRunner', split="train")
    #dataset = load_dataset('wiki40b', 'sv', beam_runner='DirectRunner')
    dataset = dataset.remove_columns(['wikidata_id', 'version_id'])
    filtered_dataset =
    # filtered_dataset[:3]
    # print(filtered_dataset[:3])
    return filtered_dataset

def filter_wikipedia(batch):
    batch["text"] = " ".join(batch["text"].split("\
    batch["text"] = " ".join(batch["text"].split("\
    batch["text"] = " ".join(batch["text"].split("\
    batch["text"] = " ".join(batch["text"].split("\
    batch["text"] = " ".join(batch["text"].split("_NEWLINE_"))
    batch["text"] = " ".join(batch["text"].split("\xa0"))
    return batch

Training script

The following training script was used to train the model.
