# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->

Cesterrewards is a Bert model that is able to predict the code coverage of Libcester unit test cases.

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

<!-- ## Uses -->

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

<!-- ### Direct Use -->

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->

<!-- [More Information Needed] -->

<!-- ### Downstream Use [optional] -->

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->

<!-- [More Information Needed] -->

Expanding the dataset will help increase the accuracy and robustness of the model, and improve code coverage predictions based on real life scenarios.

## How to Get Started with the Model

Use the code below to get started with the model.

```py
from transformers import AutoModelForSequenceClassification, AutoTokenizer
import torch

reward_name = "xavierwoon/cesterrewards"
reward_model = AutoModelForSequenceClassification.from_pretrained(reward_name)
tokenizer = AutoTokenizer.from_pretrained(reward_name)

# Change the prompt to sample unit test cases in Libcester format
prompt = """
CESTER_TEST(create_stack, test_instance,
{
    struct Stack stack;
    initStack(&stack);
    cester_assert_equal(stack.top, -1);
})
"""

inputs = tokenizer(prompt, return_tensors="pt", padding=True, truncation=True, max_length=512)
# Put the model in evaluation mode
reward_model.eval()

# Perform inference to get the reward score
with torch.no_grad():
    outputs = reward_model(**inputs)
reward_score = outputs.logits.item()  # Extract the scalar value

print("Expected Code Coverage:", reward_score)
```

## Training Details

### Training Data

<!-- This should link to a Dataset Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->

Training Data was created based on Data Structures and Algorithm (DSA) codes created using ChatGPT. It would also create corresponding Cester test cases. After testing the code coverage, it was added to the dataset under `score`.

### Training Procedure

<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. -->

1. Prompt GPT for sample DSA C code
2. Prompt GPT for Libcester unit test cases with 100% code coverage
3. Test generated test cases for code coverage and note down
