# Code Comment Quality Classifier 🔍

Automatically classify code comments into quality categories to improve code documentation and review processes.

## 🎯 Model Description

This fine-tuned DistilBERT model analyzes code comments and classifies them into **4 quality categories**:

| Category | Precision | Recall | Description |
|----------|-----------|--------|-------------|
| 🌟 **Excellent** | 100% | 100% | Clear, comprehensive, highly informative comments with context |
| ✅ **Helpful** | 88.9% | 100% | Good comments that add value but could be more detailed |
| ⚠️ **Unclear** | 100% | 79.2% | Vague, confusing, or uninformative comments |
| 🚫 **Outdated** | 92.3% | 100% | Deprecated, obsolete, or TODO comments |

### 📊 Overall Performance

- **Accuracy**: 94.85%
- **F1 Score**: 94.68%
- *🚀 Quick Start

### Using Transformers Pipeline (Easiest)

```python
from transformers import pipeline

# Load the classifier
classifier = pipeline("text-classification", model="Snaseem2026/code-comment-classifier")

# Classify comments
comments = [
    "This function uses dynamic programming for O(n) time complexity",
    "does stuff",
    "DEPRECATED: use new_function() instead"
]

results = classifier(comments)
for comment, result in zip(comments, results):
    print(f"{comment}: {result['label']} ({result['score']:.2%} confidence)")
```

### Manual Usage with Transformers

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

# Load model and tokenizer
mod💡 Use Cases

### 1. **Code Review Automation**
Automatically flag low-quality comments during pull request reviews:
```python
def check_pr_comments(file_comments):
    classifier = pipeline("text-classification", model="Snaseem2026/code-comment-classifier")
    results = classifier(file_comments)
    return [c for c, r in zip(file_comments, results) if r['label'] in ['unclear', 'outdated']]
```

### 2. **Documentation Quality Audits**
Scan codebases to identify documentation that needs improvement.

### 3. **Developer Education**
Help developers learn what constitutes good documentation practices.

### 4. **IDE Integration**
Provide real-time feedback on comment quality while coding.

### 5. **Technical Debt Analysis**
Identify outdated comments and TODOs that need addressing.

```

### Key Findings
- ✨ **Perfect classification** of excellent comments (100% precision & recall)
- 🎯 **Zero false negatives** for helpful and outdated comments
- ⚠️ Slight challenge distinguishing unclear comments from other categories
- 📊 Strong overall performance with 94.85% accuracy

## ⚠️ Limitations

1. **Synthetic Training Data**: Model trained on synthetic examples; may require fine-tuning for specific domains (e.g., scientific computing, embedded systems)
2. **English Only**: Currently supports English code comments only
3. **No Code Context**: Evaluates comments in isolation without analyzing the actual code
4. **Subjectivity**: Comment quality is inherently subjective; model reflects patterns in training data
5. **Short Comments**: May struggle with very short comments (< 3 words)

## 🎯 Intended Use

### Recommended Use
- Supplementary tool in code review automation
- Documentation quality auditing
- Developer education and training
- IDE plugins for real-time feedback

### Not Recommended
- Sole decision-maker for code quality
- Production-critical systems without human oversight
- Evaluating non-English comments
- Analyzing code quality (only evaluates comments)

## 🔧 How to Improve Performance

### Fine-tune on Your Domain
```python
from transformers import AutoModelForSequenceClassification, Trainer, TrainingArguments

# Load the pre-trained model
model = AutoModelForSequenceClassification.from_pretrained("Snaseem2026/code-comment-classifier")

# Fine-tune on your domain-specific data
training_args = TrainingArguments(
    output_dir="./fine_tuned_model",
    learning_rate=1e-5,  # Lower learning rate for fine-tuning
    num_train_epochs=2,
    per_device_train_batch_size=8,
)

trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=your_dataset,
)
trainer.train()
```
