Paragraph starter

The continuous discovery of novel materials, particularly in data-scarce domains, presents a significant challenge for generative artificial intelligence. Research by Chen et al. (2026) introduced DuALGen, a dual active learning framework that effectively mitigates data bias by coupling generative and predictive loops. This approach drives exploration of the design space through dynamic sampling and corrects distribution shifts by sampling outliers, enabling the reliable evaluation of previously unknown candidates. Applied to 2D materials, DuALGen uncovered thousands of high-performance electronic material candidates, demonstrating a practical route to continuous innovation in materials discovery.
