ELECTRICIDAD: The Spanish Electra Imgur
Electricidad-base-discriminator (uncased) is a
base Electra like model (discriminator in this case) trained on a + 20 GB of the OSCAR Spanish corpus.
As mentioned in the original paper: ELECTRA is a new method for self-supervised language representation learning. It can be used to pre-train transformer networks using relatively little compute. ELECTRA models are trained to distinguish "real" input tokens vs "fake" input tokens generated by another neural network, similar to the discriminator of a GAN. At small scale, ELECTRA achieves strong results even when trained on a single GPU. At large scale, ELECTRA achieves state-of-the-art results on the SQuAD 2.0 dataset.
For a detailed description and experimental results, please refer the paper ELECTRA: Pre-training Text Encoders as Discriminators Rather Than Generators.

from transformers import ElectraForPreTraining, ElectraTokenizerFast import torch discriminator = ElectraForPreTraining.from_pretrained("/content/electricidad-base-discriminator") tokenizer = ElectraTokenizerFast.from_pretrained("/content/electricidad-base-discriminator") sentence = "El rápido zorro marrón salta sobre el perro perezoso" fake_sentence = "El rápido zorro marrón amar sobre el perro perezoso" fake_tokens = tokenizer.tokenize(fake_sentence) fake_inputs = tokenizer.encode(fake_sentence, return_tensors="pt") discriminator_outputs = discriminator(fake_inputs) predictions = torch.round((torch.sign(discriminator_outputs) + 1) / 2) [print("%7s" % token, end="") for token in fake_tokens] [print("%7s" % prediction, end="") for prediction in predictions.tolist()] # Output: ''' el rapido zorro marro ##n amar sobre el perro pere ##zoso 0.0 0.0 0.0 0.0 0.0 0.0 1.0 1.0 0.0 0.0 0.0 0.0 0.0[None, None, None, None, None, None, None, None, None, None, None, None, None '''
As you can see there are 1s in the places where the model detected a fake token. So, it works! 🎉
