MovieCert Marathi Teacher Model
Model Details
Model Description
This repository contains the Marathi Teacher model developed for the research paper "Lightweight and Explainable Neural Models for Multilingual Movie Script Certification."
The model is fine-tuned from the multilingual DistilBERT architecture to classify full Marathi movie scripts into age-rating categories. It serves as the teacher model in a knowledge distillation framework used to develop lightweight student models for efficient deployment.

Model Sources
Uses
Direct Use
This model is intended for automated classification of Marathi movie scripts into age-rating categories.
Potential applications include:
- Automated movie certification research
- Movie script analysis
- Content moderation
- Academic NLP research
- Benchmarking multilingual transformer models
Downstream Use
The model may be used as:
- Teacher model for knowledge distillation
- Base model for further fine-tuning
- Feature extractor
- Long-document text classification research
Out-of-Scope Use
This model is not intended for:
- Legal or official movie certification decisions
- Safety-critical systems
- Hate speech detection
- Sentiment analysis
- Medical or legal decision making
Predictions should not replace human review.
Bias, Risks and Limitations
The model was trained using a curated dataset of Marathi movie scripts and inherits limitations of the dataset, including:
- Limited dataset size
- Possible class imbalance
- Genre imbalance
- Cultural bias
- Language-specific ambiguity
Performance may decrease on scripts that differ substantially from the training distribution.
Recommendations
The model should be used as an assistive tool rather than a replacement for human reviewers.
Training Details
Training Data
