How google-research/bert Works

BERT is based on the transformer architecture and relies on self-attention mechanisms that analyze the text contextualized in a bidirectional way. While older models may have read through the text sequence by sequence, as it were, from both directions, BERT does this to a far greater degree, making its understanding much better-informed.

The model has two major phases: pre-training and fine-tuning. During pre-training, the model learns from an enormous corpus of text; fine-tuning tunes the model to specific tasks with a small dataset.

Workflow:

• 
  Tokenization:
  
  Text is divided into tokens.
• 
  Embedding:
  
  Tokens are embedded into the numerical representations.
• 
  Transformer Layers:
  
  Data flows through the stack of transformer layers to know about context.
• 
  Output:
  
  Makes predictions based on what data has been processed.

Pros and Cons of google-research/bert

Pros:

• State-of-the-art accuracy in many NLP tasks.
• Pre-trained models save time and resources.
• Open-source nature so the community can contribute.

Cons:

• Computational needs go up with bigger models.
• Steep learning curve.

User feedback generally speaks to the model’s proficiency in comprehension of context and an improvement in NLP tasks, though it requires quite a lot of computational power for applications that demand such intensity.
