【 摘 要 】

JOHN MCCARTHY, computer scientist at Stanford University, firstcoined the term "artificial intelligence” in 1955, defining it as, "the science and engineering of making intelligent machines, especially intelligent computer programs.”Machines are intelligent when they can replicate human cognitive skills such as forming categories, recognizing patterns, and solving problems. For machines to achieve artificial intelligence, computer programmers must create algorithms that can scan and organize input data to train and teach the machines to perform tasks. This method is called machine learning, the most basic of all AI techniques. Several other AI methods have since been developed, including neural network, a process that mimics how the human brain learns by using interconnected nodes to process data. Its moresophisticated version is called deep learning, which uses multiple layersof neural networks so that computers can analyze bigger datasets. Withthe advent of big geospatial data, there are far more inputs for AI machines to train on and improve their accuracy. And due to AI's ability to handle bigdatasets such as imagery, computer vision is currently one of the hottestgeospatial applications. With computer vision technology, machinescan be taught to "see” real-world objects from images, thus allowingcompanies like Mapillary to identify roads from street photos, Ecopia toextract built-up areas from satellite imagery, and VOXELGRIDto recognize construction materials from a point cloud.
