Abstract: An embodiment of the invention provides a method that identifies GPS shifting fields for road segments, the GPS shifting fields including areas around the road segments that include false GPS readings of objects that traveled on the road segments. The GPS shifting fields can be revised with a road segment attribute and/or at a driver preference. The road map network can be partitioned into space units, where the road map network can include at least two GPS readings of the object. For each space unit that includes a road segment, a probability that the object was located on the road segment can be calculated for each road segment based on the GPS readings of the object and the GPS shifting fields. The trajectory of the object can be determined based on the computing of the probabilities.

Abstract: A method and system for obtaining a trajectory pattern of a route. One embodiment of the present invention provides a method for obtaining a trajectory pattern of a route. The method includes obtaining a set of points associated with the route, the set of points being obtained by at least one entity travelling along the route. A plurality of coverage areas covering a part of points in the set of points is determined. The coverage areas are connected based on main directions of the coverage areas to obtain the trajectory pattern related to the route. The main directions represent forward directions of the route in respective coverage areas. A corresponding system for obtaining a trajectory pattern of a route is described as well.

Abstract: Methods and systems for circuit generation include generating a circuit design. Paths are extracted from the circuit design, with the paths representing sequences of connected circuit components from one terminal of the circuit to another. The extracted paths are embedded as respective vectors in a latent space. A property of the circuit design is determined using an ensemble of trained surrogate models that accept a sequence of the vectors as input.
