Overview

Slide 84 introduces how generative models transform input representations into meaningful outputs through a structured reasoning and decoding process. It highlights how models evaluate context, predict the next tokens, and refine outputs.

Key Concepts

Token Processing

Input text is broken into tokens, which become numerical vectors for the model to process.

Context Attention

The model weighs relationships among tokens using attention layers to determine meaning.

Generative Decoding

Probabilities are used to generate coherent text or output results, one step at a time.

How the Process Works

1

Input Encoding

Convert text into embeddings using tokenizers.

2

Attention Layers

Model learns relationships across tokens.

3

Probability Prediction

Outputs probability distribution of next possible tokens.

4

Token Generation

Decodes and outputs next token repeatedly to generate results.

Applications

Comparison: Traditional ML vs Generative AI

Traditional ML

  • Predictive models
  • Fixed outputs
  • Requires structured data
  • Task-specific training

Generative AI

  • Creates new content
  • Flexible multi-task capability
  • Uses large-scale unstructured datasets
  • Context-aware reasoning

Frequently Asked Questions

What does Slide 84 illustrate?

It explains the internal decision-making and generation process of a transformer-based generative model.

Why are attention layers important?

They help determine which parts of the input text are most relevant for predicting the next token.

How does this apply to real applications?

It powers chatbots, assistants, automation tools, and creative generation systems.
