# Mistral-7B-Mortgage-Loans-v1

## Model Description

This model, "Mistral-7B-Mortgage-Loans-v1," is a fine-tuned version of [mistralai/Mistral-7B-Instruct-v0.2](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2) developed to specifically address queries related to mortgage and loans. It provides answers that are crucial for understanding complex loan processes and mortgage applications.

## Intended Use

- **Recommended applications**: This model is particularly useful for financial institutions, mortgage brokers, and loan providers. It is designed to integrate into customer support systems to help users understand their loan options, mortgage details, and payment plans.
- **Out-of-scope**: This model is not designed for non-financial inquiries and should not be used to provide legal, medical, or other advice outside of its financial expertise area.

## Usage Example

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("bitext-llm/Mistral-7B-Mortgage-Loans-v1")
tokenizer = AutoTokenizer.from_pretrained("bitext-llm/Mistral-7B-Mortgage-Loans-v1")

inputs = tokenizer("<s>[INST] What are the requirements for a home loan? [/INST]", return_tensors="pt")
outputs = model.generate(inputs['input_ids'], max_length=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

## Model Architecture

The model utilizes the `MistralForCausalLM` architecture along with a `LlamaTokenizer`. It retains the fundamental characteristics of the base model while being optimized to understand and generate responses in the context of mortgage and loans.

## Training Data

The model was trained on a dataset specifically designed for the mortgage and loan sector, featuring 39 intents including `apply_for_loan`, `check_loan_terms`, `refinance_loan`, `customer_service`, and many others, each with nearly 1000 examples. This rich dataset ensures the model's proficiency in addressing a broad spectrum of inquiries within this domain. The dataset follows the same structured approach as our dataset published on Hugging Face as [bitext/Bitext-customer-support-llm-chatbot-training-dataset](https://huggingface.co/datasets/bitext/Bitext-customer-support-llm-chatbot-training-dataset), but with a focus on mortgage and loans.

## Training Procedure

### Hyperparameters

- **Optimizer**: AdamW
- **Learning Rate**: 0.0002 with a cosine learning rate scheduler
- **Epochs**: 4
- **Batch Size**: 10
- **Gradient Accumulation Steps**: 8
- **Maximum Sequence Length**: 8192 tokens

### Environment

- **Transformers Version**: 4.40.0.dev0
- **Framework**: PyTorch 2.2.1+cu121
- **Tokenizers**: Tokenizers 0.15.0

## Limitations and Bias

- The model is fine-tuned on a domain-specific dataset and may not perform well outside the scope of financial advice.
- Users should be aware of potential biases in the training data, as the model's responses may inadvertently reflect these biases. This model has been trained with a dataset that answers general mortgage and loans questions, so potential biases may exist for specific use cases.

## Ethical Considerations

This model should be used responsibly, considering ethical implications of automated financial advice. As it is a base model for this financial field, it is crucial to ensure that the model's advice complements human expertise and adheres to relevant financial regulations.
