Project Title

bertviz — Visualizing Attention in NLP Models for Deeper Understanding

Overview

BertViz is an interactive Python tool designed to visualize attention in Transformer-based language models such as BERT, GPT2, and T5. It offers a simple API for use within Jupyter or Colab notebooks, supporting most Huggingface models. BertViz extends the Tensor2Tensor visualization tool, providing multiple views to analyze the attention mechanism from various perspectives.

Key Features

Head View: Visualizes attention for one or more attention heads in the same layer.
Model View: Offers a bird's-eye view of attention across all layers and heads.
Neuron View: Visualizes individual neurons in the query and key vectors to show how they compute attention.

Use Cases

NLP Researchers: Use BertViz to understand how attention mechanisms work in different models.
Educators: Utilize the tool to teach students about the inner workings of Transformer models.
Model Developers: Debug and optimize attention mechanisms in custom NLP models.

Advantages

Interactive Visualizations: Provides multiple views for a comprehensive understanding of attention mechanisms.
Compatibility: Works with most Huggingface models, making it versatile for various NLP tasks.
Ease of Use: Simple Python API allows for quick integration into Jupyter or Colab notebooks.

Limitations / Considerations

Complexity: May require a certain level of understanding of NLP and attention mechanisms to fully utilize.
Performance: Visualizations can be resource-intensive, potentially affecting performance on less powerful machines.

Tensor2Tensor: The original visualization tool that BertViz extends, focusing on TensorFlow models.
Attention is All You Need: A paper that introduced the Transformer model, which BertViz helps visualize.
Huggingface Transformers: A library of pre-trained models that BertViz is compatible with, offering a wide range of NLP capabilities.
