Introduction to Meta Learning

🎯 What is Meta Learning?

Meta-learning, or "learning to learn," trains models to quickly adapt to new tasks using minimal data by learning from a diverse set of related tasks during meta-training.

🧠
Core Idea

Learn general learning strategies that transfer across tasks

🔍 Few-Shot Learning Problem

Train models to recognize new classes with only a few labeled examples per class.

1-Shot Learning

One example per class

5-Shot Learning

Five examples per class

N-Way K-Shot

K examples, N classes

🌟 Why Meta Learning?

Data Efficiency

Learn from few examples, crucial when data is scarce or expensive

🚀

Fast Adaptation

Quickly adapt to new tasks without extensive retraining

🌍

Generalization

Transfer knowledge across diverse but related tasks

🎯

Robustness

Learn invariant features that work across task variations

📚 Meta Learning Framework

Meta-Training (Outer Loop)

Sample diverse tasks from task distribution, optimize meta-parameters

Task Learning (Inner Loop)

Adapt to specific task using support set (training examples)

Meta-Testing

Evaluate on completely new tasks from same distribution

🎲 Task Terminology

Support Set

Training

Few labeled examples for task adaptation (K examples × N classes)

Query Set

Testing

Unlabeled examples to test task performance after adaptation

Episode

Unit

Single task sampled during meta-training (support + query)

🏆 Applications

Computer Vision

Few-shot image classification, object detection with limited data

NLP

Low-resource language tasks, intent classification, translation

Robotics

Quick adaptation to new environments and manipulation tasks

Drug Discovery

Predict molecular properties with limited labeled compounds
