NourhanAbosaeed/Coursera_Reviews_Sentiment_Analysis_DistillBERT

This model is a fine-tuned version of distilbert-base-uncased on an a dataset from Cousera courses reviews, It is publicly available on Kaggle since 2017.

After data preprocessing and model training, It achieves the following results on the evaluation set:

• Train Loss: 0.4934
• Validation Loss: 0.6018
• Train Accuracy: 0.7498
• Epoch: 2

Considering the imbalanced nature of the data, metrics such as recall, precision, and F1 score were employed for evaluation:-

The model achieves these results on the test set:

Training and evaluation data

After cleaning the data, It becomes 93291 training size, 11661 for validation and 11662 for test sets.

There are 3 lables positive, negative and netural.

The data have imbalanced nature so I have used class weights during training.
