RoBERTa Student Articulation Classifier
Fine-tuned roberta-base for classifying student coding check-ins into 4 articulation levels.
Labels
| ID | Label | Description |
|---|---|---|
| 0 | Minimal | Vague, no technical detail |
| 1 | Basic | Names a tool or action, no implementation detail |
| 2 | Developing | Specific and technical but incomplete |
| 3 | Proficient | Full technical ownership — implementation, reasoning, testing |
Usage
from transformers import pipeline
classifier = pipeline(
"text-classification",
model="your-username/roberta-articulation-classifier"
)
result = classifier("I implemented JWT auth with refresh token rotation and wrote integration tests.")
print(result)
# [{'label': 'Proficient', 'score': 0.92}]
