Innovations

Introduction of INS2ANE framework for novelty discovery in autonomous experiments
Novelty scoring system that evaluates the uniqueness of experimental results
Strategic sampling mechanism that promotes exploration of under-sampled regions even if less promising by conventional criteria

Methodology

The INS2ANE framework integrates a novelty scoring system to evaluate uniqueness of experimental results and a strategic sampling mechanism to explore under-sampled regions. It was validated on a pre-acquired dataset of image-spectral pairs with known ground truth and implemented on autonomous scanning probe microscopy experiments.

Key Results

INS2ANE significantly increases the diversity of explored phenomena compared to conventional optimization routines, enhancing the likelihood of discovering previously unobserved phenomena.
