Designing synthetic datasets for the real world: Mechanism design and reasoning from first principles

Google Research 3 months ago

Google researchers introduced Simula, a framework for generating synthetic datasets using mechanism design and reasoning-first principles rather than manual prompts or evolutionary algorithms. The system decomposes dataset generation into controllable axes including global diversification, local diversification, complexification, and quality checks, and has been deployed across Google's products including Gemma models, Gemini safety classifiers, and user protection features like scam detection. The work demonstrates that synthetic data generation can be treated as a controllable science, enabling specialized AI models to be trained on high-fidelity datasets in domains where real-world data is scarce or inaccessible.

AI-generated synthetic neurons speed up brain mapping

Google Research 3 months ago

Google Research developed MoGen, an AI model that generates synthetic neuronal shapes to improve the accuracy of brain mapping reconstruction algorithms. Training the PATHFINDER neuron reconstruction model with 10% synthetic data from MoGen reduced reconstruction errors by 4.4%, which translates to 157 person-years of manual proofreading saved for a complete mouse brain. The approach enables faster and more scalable brain mapping by reducing the manual verification work required from human experts.
