AI approach

PostMath uses AI for various educational technologies, including Optical Character Recognition (OCR) to accurately convert handwritten math problems into text, Dynamic Semantic Structuring (DSS) for analyzing and organizing problems across different curricula, and an AI technology called LDM (mathematically similar image automatic matching) to analyze shapes and graphs in problems to find semantically similar images. They also employ a micro-fine math classification system and a math ontology to connect concepts and problems through common tags.
