Foundation Models for Few-Shot Learning: Adapting to New Tasks Instantly

The ability to learn from few examples is a hallmark of human intelligence. Our research enables AI systems to do the same.

The Few-Shot Challenge

Traditional ML requires thousands of examples. In contrast, humans can:

  • Learn new concepts from 1-2 examples
  • Generalize systematically
  • Compose known concepts
  • Transfer across domains

Approach

We leverage foundation models through:

In-Context Learning

  • Provide examples in the prompt
  • No weight updates required
  • Instant adaptation
  • Task specification via demonstration

Meta-Learning

  • Learn to learn from pretraining
  • Fast adaptation mechanisms
  • Task-agnostic representations
  • Optimization-based methods

Retrieval Augmentation

  • Find similar examples
  • Contextual retrieval
  • Knowledge base integration
  • Dynamic few-shot selection

Real-World Impact

Enabling applications with:

  • Limited training data
  • Rapidly changing categories
  • Long-tail distributions
  • User personalization
