BERT News Intelligence v1 — Fine-Tuned Transformer for News Classification
This project is developed as part of applied NLP research in transformer-based language models, focusing on fine-tuning pretrained architectures for real-world text intelligence systems.
The work demonstrates expertise in:
- Natural Language Processing (NLP)
- Transformer Architectures (BERT-based models)
- Deep Learning Fine-Tuning Strategies
- Model Evaluation & Benchmarking
- Production-Ready ML Pipelines (Hugging Face Ecosystem)
This is not just a classification model — it is a research-driven transformer adaptation system for domain-specific intelligence extraction.
Model Overview
A fine-tuned BERT (bert-base-uncased) model for automatic news topic classification.
It categorizes news into:
- World
- Sports
- Business
- Science & Technology
Problem Statement
Traditional rule-based or manual news categorization systems:
- Do not scale
- Lack semantic understanding
- Fail on ambiguous text
This system solves the problem using context-aware transformer representations, enabling semantic-level classification.
