Reasoning-driven synthetic data generation from first principles
Construct synthetic datasets by reasoning from first principles, not just optimizing individual samples.
Reframe synthetic data generation as dataset-level mechanism design, constructing entire datasets from first principles.
Instead of optimizing single data points or relying on manual prompts and seed data, Simula builds datasets by architecting their structure and content through a recursive, reasoning-driven process. This ensures better control over global diversity, local variation, complexity, and quality.
Building a legal reasoning dataset by first defining the core legal concepts and their relationships (taxonomy), then generating diverse case scenarios (meta-prompts) for each concept, and finally refining some cases to be more complex and ensuring label accuracy.
This heuristic suggests approaching synthetic data generation as a mechanism design problem. Instead of optimizing sample by sample, construct the entire dataset from first principles using reasoning. This allows for better control over coverage, complexity, and quality, especially for specialized or data-scarce domains.
Operating at the dataset level and using reasoning from first principles provides a more principled and controllable way to generate data that meets specific requirements for coverage, complexity, and quality.
