However, labels from weak supervision can be rather noisy and the high capacity of DNNs makes them easy to overfit the noisy labels.

Incorrect labels in training data occur when human annotators make mistakes or when the data is generated via weak or distant supervision.

Our approach automatically augments the data available for training by (i) generating new text samples based on replacing specific values by alternative ones from the same category, (ii) generating new text samples based on GPT-2, and (iii) proposing an automatic method for pairing the new text samples with data samples.

Distant and weak supervision allow to obtain large amounts of labeled training data quickly and cheaply, but these automatic annotations tend to contain a high amount of errors.
