BERT (Bidirectional Encoder Representations from Transformers) is a groundbreaking Transformer-based model that has revolutionized NLP tasks. 🧠

What is BERT?

  • Pre-trained model: BERT is trained on vast text corpora to understand context and meaning.
  • Bidirectional: It processes text in both forward and backward directions, capturing nuanced relationships.
  • Fine-tuning: Easily adaptable to specific tasks like text classification or QA systems.

Key Features

  • Contextual embeddings: Generates word representations based on surrounding text. 📚
  • Masked LM: Predicts randomly masked words in a sentence. 🔍
  • Next sentence prediction: Determines if two sentences are related. 💡
