Abstract
Systems and methods that infer and classify user activity based in part on routing data. A storage medium can store raw data collected, and such acquired data can be subsequently be analyzed or distilled to generate abstract qualities about the raw data (e.g., velocity of user during route, level of difficulty, and the like). Various machine learning techniques, artificial intelligence methodologies, decision trees, and/or statistical methods can be employed to supply inference regarding the acquired raw data and/or the abstract qualities.
