AI can solve partial differential equations thousands of times faster than before, and partial differential equations play an important role in engineering and science. In a recent study, scientists from Johns Hopkins University in the United States have developed a new artificial intelligence (AI) model called "Differential Mapping Operator Learning" (DIMON), which can solve complex partial differential equations on personal computers, thousands of times faster than before, and is expected to "show its talents" in the fields of aerospace, automobiles and medicine.
