Revolutionizing LLM Adaptation:
TEST-TIME META-ADAPTATION WITH SELF-SYNTHESIS
Large Language Models (LLMs) encounter diverse domains and tasks, where the ability to adapt and self-improve at test time is valuable. They are typically deployed as static artifacts but need to continuously adapt to evolving tasks, new information, and shifting distributions.
We introduce MASS, a meta-learning framework that enables LLMs to self-adapt by generating problem-specific synthetic training data and performing targeted self-updates optimized for downstream performance at inference time.
Executive Impact & Key Innovations
MASS, a novel meta-learning framework, empowers Large Language Models (LLMs) to dynamically self-adapt at inference time by generating targeted synthetic training data. This approach addresses the critical need for LLMs to continuously evolve with new tasks and shifting distributions, moving beyond static deployments.
- ✓ Bilevel Optimization: MASS uses an inner loop for adaptation on self-generated examples and an outer loop for meta-learning data-attribution signals and rewarding post-update task performance.
- ✓ Synthetic Data Generation: It actively synthesizes problem-specific training data, which is optimized using scalable meta-gradients to ensure useful generations.
- ✓ Mathematical Reasoning: Demonstrated effectiveness in mathematical reasoning across diverse fields, showing the ability to construct per-instance curricula for data-efficient adaptation.
- ✓ Scalable Self-Improvement: Offers a scalable alternative to massive offline pretraining, enabling models to leverage test-time compute for precise, problem-specific adjustments.

MASS Architecture: Bilevel Optimization Flow
MASS operates on a bilevel optimization framework. An inner loop adapts the model on self-generated examples, while an outer loop meta-learns data-attribution signals and rewards post-update task performance. This architecture allows for a problem-specific synthetic curriculum.
