text_shortening_model_v1
This model is a fine-tuned version of t5-small on a dataset of 699 original-shortened texts pairs of advertising texts. It achieves the following results on the evaluation set:
- Loss: 1.9266
- Rouge1: 0.4797
- Rouge2: 0.2787
- Rougel: 0.4325
- Rougelsum: 0.4321
- Bert precision: 0.8713
- Bert recall: 0.8594
- Average word count: 10.0714
- Max word count: 18
- Min word count: 1
- Average token count: 15.45
Model description
Data is cleaned and preprocessed: "summarize" prefix added for each original text input.
Loss is a combination of:
- CrossEntropy
- Custom loss which can be seen as a length penalty: +1 if predicted text length > 12, else 0
Loss = theta * Custom loss + (1 - theta) * CrossEntropy
(theta = 0.3)
Intended uses & limitations
More information needed
Training and evaluation data
699 original-shortened texts pairs of advertising texts of various lengths.
- Original texts lengths: > 12
- Shortened texts lengths: < 13
Splitting amongst sub-datasets:
- 70% of the dataset is used for training
- 20% of the dataset is used for validation
- 10% of the dataset is kept for testing
