Model specs

This model is a fine-tuned version of spanish-t5-small on the data described below. It achieves the following results on the evaluation set:

• 'eval_bleu': 93.8347,
• 'eval_f1': 0.9904,

Training procedure

Training hyperparameters

The following hyperparameters were used during training:

• learning_rate: 1e-04
• train_batch_size: 32
• seed: 42
• num_epochs: 10
• weight_decay: 0,01

Training and evaluation data

Metrics

For training, we used both Blue (sacrebleu implementation in HF) and BertScore. The first one, a standard in Machine Translation processes, has been added for ensuring robustness of the newly generated data, while the second one is kept for keeping the expected semantic similarity.

However, given the actual use case, we expect generated segments to be very close to input segments and to label segments in training. As an example, we can take the following:

inputSegment = 'De acuerdo con las informaciones anteriores , las alumnas se han quejado de la actitud de los profesores en los exámenes finales. Los representantes estudiantiles son los alumnos Juanju y Javi.' expectedOutput (label) = 'De acuerdo con las informaciones anteriores, el alumnado se ha quejado de la actitud del profesorado en los exámenes finales. Los representantes estudiantiles son los alumnos Juanju y Javi.' actualOutput = 'De acuerdo con las informaciones anteriores, el alumnado se ha quejado de la actitud del profesorado en los exámenes finales. Los representantes estudiantiles son el alumnado Juanju y Javi.'

As you can see, segments are pretty similar. So, instead of measuring Bleu or BertScore here, we propose an alternate metric that would be DiffBleu:

$$DiffBleu=BLEU(actualOutput-inputSegment,labels-inputSegment)DiffBleu\; =\; BLEU(actualOutput\; -\; inputSegment,\; labels\; -\; inputSegment)$$

Where the minuses as in set notation. This way, we also evaluate DiffBleu after the model has been trained.
