Adaptive and Personalized Navigation System
First Claim
1. A machine-readable storage medium encoded with instructions that, when executed by one or more processors, cause the processor to carry out a process for generating directions for use in navigation during a current driving session, the process comprising:
- receiving a target destination;
generating at least one candidate route;
probabilistically determining that one of a plurality of conditional variant models associated with a target attribute corresponds to a condition of the target attribute, the plurality conditional variant models learned from previous user driving sessions; and
scoring the at least one candidate route using the determined conditional variant model; and
providing a scored route to a user.

Abstract
Adaptive navigation techniques are disclosed that allow navigation systems to learn from a user'"'"'s personal driving history. As a user drives, models are developed and maintained to learn or otherwise capture the driver'"'"'s personal driving habits and preferences. Example models include road speed, hazard, favored route, and disfavored route models. Other attributes can be used as well, whether based on the user'"'"'s personal driving data or driving data aggregated from a number of users. The models can be learned under explicit conditions (e.g., time of day/week, driver ID) and/or under implicit conditions (e.g., weather, drivers urgency, as inferred from sensor data). Thus, models for a plurality of attributes can be learned, as well as one or more models for each attribute under a plurality of conditions. Attributes can be weighted according to user preference. The attribute weights and/or models can be used in selecting a best route for user.
