Model Compression

41 SLIDES Part 4: Applications

?
The 350GB Problem: GPT-3 requires 350GB of memory. Your laptop has 16GB. That's 22x larger than your RAM. How do we make AI run anywhere?

Prerequisites

  • Understanding of neural network architectures
  • Week 6-7: Large language model basics
  • Familiarity with floating-point number representation

Overview

Make models smaller and faster. Quantization, pruning, and knowledge distillation.

Learning Objectives

  • Explain why model compression is essential for deployment
  • Apply quantization techniques (INT8, INT4) to reduce model size
  • Understand knowledge distillation for creating smaller models
  • Compare pruning strategies (unstructured vs structured)
  • Evaluate trade-offs between size, speed, and accuracy

Key Topics

Quantization
Pruning
Distillation
Inference optimization

Key Concepts

QuantizationReduce precision (FP32 to INT8/INT4) for 4-8x compression
Knowledge distillationTrain small "student" from large "teacher"
PruningRemove unnecessary weights/neurons
Model compression pipelineCombine techniques for maximum efficiency
Inference optimizationKV-cache, batching, hardware acceleration
Edge deploymentRunning models on phones and laptops
