Compositionality

Image caption: Princeton researchers have found that the prefrontal cortex of primates reuses modular thinking blocks to solve similar tasks. This gives biological brains a flexibility that artificial intelligence still lacks. The insight could help improve AI systems so that they retain old skills even as they learn new ones.
