1. A machine-readable, non-transitory storage medium encoded with instructions that, when executed by one or more processors, cause the one or more processors 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 of conditional variant models learned from previous user driving sessions;

    scoring the at least one candidate route using the determined conditional variant model;

    providing a scored route to a user;

    detecting a change in the condition of the target attribute,wherein the detecting a change in the condition of the target attribute comprises;

    recomputing probabilities for the conditional variant models associated with the target attribute periodically during the current driving session using subsequently observed data of the current driving session; and

    probabilistically determining that a second conditional variant model currently corresponds to the condition of the target attribute; and

    providing an altered route to the user based on the detected change.
