finetuning-sentiment-model-bank_reviews-otherbank

This model is a fine-tuned version of distilbert/distilbert-base-uncased-finetuned-sst-2-english on app store reviews from OCBC bank and POSB bank (Singapore). It achieves the following results on the evaluation set:

• Loss: 0.4811
• Accuracy: 0.8630
• F1: 0.6970

Model description

Data was labelled according to review stars. If stars >3, review was ranked positive. Otherwise, it is labelled as negative. We have tried 4 stars instead of 3 as app developers would deem any negativity in reviews as negative as a whole, but accuracy dropped. Further investigations will need to be run. Above 4 stars positive: https://huggingface.co/ajiayi/finetuning-sentiment-model-bank_reviews-otherbank-4insteadof3 All data (OCBC,POSB,GXS): https://huggingface.co/ajiayi/finetuning-sentiment-model-bank_reviews

Intended uses & limitations

Model was used in the following project: https://github.com/weixuanontherun/DSA3101_Group-19 It was finetuned using OCBC and POSB and tested on GXS bank reviews.
