This is a SetFit model trained on the rbojja/labelled_bank_support_dataset dataset that can be used for Text Classification. This SetFit model uses BAAI/bge-small-en-v1.5 as the Sentence Transformer embedding model. A LogisticRegression instance is used for classification.

The model has been trained using an efficient few-shot learning technique that involves:

Fine-tuning a Sentence Transformer with contrastive learning.
Training a classification head with features from the fine-tuned Sentence Transformer.

Model Labels

Label	Examples
1	'Can you explain the differences between fixed and variable interest rates for personal loans?' 'Can you clarify why I was charged a fee for my account this month?' 'How can I access your customer service features if I need assistance?'
2	'Could you please verify that my deposit cancellation has been completed?' "I've noticed a discrepancy in my balance after my latest deposit. Can you confirm if it was processed correctly?" 'Could you verify that my recent payment has been reversed successfully?'
3	"How do changes in the central bank's interest rates affect the interest I earn on my savings account?" 'Can I share my success story about earning rewards for referring friends? The incentives really helped me and I think others should know!' 'After my recent loan denial, how can I strengthen my reapplication to improve my approval odds?'
10	"I just made a payment, but I'm not sure if it's been processed yet. Can you check for me?" 'I think there might be an error with my account balance; can you show me my most recent transactions?' 'I expected my payment to be completed by now, can you check the status for me?'
9	'Can you please pass on my thanks to the customer service representative who helped me with my account security concerns? Their support made all the difference!' 'I just wanted to say thank you for the quick help with my issue!' 'I want to express my appreciation for the security alerts I received. It’s nice to know my account is being protected so well!'
4	"I'm ending my account with you; can you provide a summary of my final transaction?"
7	'Can I leave a review about my downgrade process? I have some suggestions for improvement.' 'Can you send me a notification of all my completed payments for this month?' 'Can you tell me how I can benefit from any investment opportunities with your bank?'
6	'I just checked my banking statement and I don’t recognize this last charge. How can I contest that?' "I believe I've been incorrectly charged for a subscription service. What steps do I take?" 'I appreciate the service you provide, but the support response time during the outage was unacceptable.'
0	'I’m sorry, but I need to check on a transaction that was denied because of insufficient funds. Can you help me resolve this situation?' "I'm really sorry, but I still can't access my account even after resetting my password. What should I do next?" "I've been mistakenly locked out of my account and I feel bad about it. Can you assist me in regaining access?"
8	'I recently used your services and I’m really satisfied. Is there a way to share my thoughts on my overall banking experience?' 'I think it would be great if final account statements could be sent out at the beginning of the month instead of the end. It allows for better planning and review.' 'I wanted to share that I found the loan application submission very straightforward. When can I expect to hear back about my approval?'
