Learning Objectives#
By the end of this module, you will:
Complete the ML evolution story by building GPT-style transformers with components you created for computer vision
Prove framework universality using 95% component reuse from MLPs (52.7%) and CNNs (LeNet-5: 47.5%)

Implement autoregressive language generation using the same Dense layers that powered your CNNs
Experience framework generalization - how one set of mathematical primitives enables any AI task
Master the complete ML timeline from 1980s foundations to modern language models
What Makes This Revolutionary#
This module proves that modern AI is built on universal foundations:
95% component reuse: Your MLP tensors, CNN layers, and training systems work unchanged for language
Historical continuity: The same math that achieved 52.7% on CIFAR-10 now powers GPT-style generation
Framework universality: Vision and language are just different arrangements of identical operations
Career significance: You understand how AI systems generalize across any domain
