Method, apparatus and computer program for estimating driver's personality of route selection

An apparatus for estimating a parameter of an evaluation function used for selecting a route from a departure point to an arrival point, comprising:

• an information acquisition unit configured to acquire information concerning a departure point and an arrival point and information concerning a route from the departure point to the arrival point;
• a basic route generation unit configured to generate a plurality of basic routes on the basis of the acquired information concerning the departure point and the arrival point and the acquired information concerning the route from the departure point to the arrival point;
• a route selection information acquisition unit configured to acquire information concerning a route actually selected;
• a parameter calculation unit configured to calculate a parameter of an evaluation function that yields the actually selected route as an optimum route among the plurality of basic routes and the actually selected route;
• a route generation unit configured to generate a new route using the calculated parameter;
• a determination unit configured to determine whether or not the generated new route is identical to the actually selected route;
• a repetition unit configured to, on a condition that the determination unit determines that the generated new route is not identical to the actually selected route, add the generated new route to the basic routes, calculate a parameter of the evaluation function anew, repeat generation of a new route, and compare the generated new route with the actually selected route;
• and
• a parameter storage unit configured to, on a condition that the determination unit determines that the generated new route is identical to the actually selected route, store the parameter at the time when the new data becomes identical to the actually selected route as a parameter of the evaluation function.

A computer readable storage medium having computer readable code stored thereon that, when executed by a computer, implement method for estimating a parameter of an evaluation function used for selecting a route from a departure point to an arrival point, the method comprising:

• acquiring, with a processing device, information concerning a departure point and an arrival point and information concerning a route from the departure point to the arrival point;
• generating a plurality of basic routes on the basis of the acquired information concerning the departure point and the arrival point and the acquired information concerning the route from the departure point to the arrival point;
• acquiring information concerning a route actually selected;
• calculating a parameter of an evaluation function that yields the actually selected route as an optimum route among the plurality of basic routes and the actually selected route;
• generating a new route using the calculated parameter;
• determining whether or not the generated new route is identical to the actually selected route;
• on a condition that it is determined that the generated new route is not identical to the actually selected route, adding the generated new route to the basic routes, calculating a parameter of the evaluation function anew, repeating generation of a new route, and comparing the generated new route with the actually selected route;
• and
• on a condition that it is determined that the generated new route is identical to the actually selected route, storing the parameter at the time when the new data becomes identical to the actually selected route as a parameter of the evaluation function.

A method for estimating a parameter of an evaluation function used for selecting one element or a combination of a plurality of elements, the method comprising:

• acquiring, with a processing device, information concerning each of the elements;
• generating a basic set including a selectable one element or a selectable combination of a plurality of elements on the basis of the acquired information concerning each of the elements;
• acquiring information concerning one actually selected element or an actually selected combination of a plurality of elements;
• and
• calculating a parameter of the evaluation function that yields the actually selected one element or the actually selected combination of a plurality of elements as an optimum one among the basic set.
