Abstract: Techniques are disclosed relating to machine learning techniques for determining geographic coordinates for an address. In some embodiments, a computer system may access address information for an address that includes one or more address elements. Based on this address information, the computer system, in some embodiments, may use a machine learning model to geographic coordinates for the address. For example, a tokenization layer of the machine learning model may generate token values based on the address elements in the address, and an embedding layer of the model may create corresponding word-embedding values based on these token values. Based on the word-embedding values, an encoder layer may generate comparative vectors that may then be decoded by a decoder layer into first and second decoded values. The first and second decoded values may then be converted into geographic coordinates for the address by an output layer of the machine learning model.
