    Abstract = {This paper describes a probabilistic approach to the problem of recognizing
    places based on their appearance. The system we present is not limited
    to localization, but can determine that a new observation comes from
    a previously unseen place, and so augment its map. Effectively this
    is a SLAM system in the space of appearance. Our probabilistic approach
    allows us to explicitly account for perceptual aliasing in the environment--identical
    but indistinctive observations receive a low probability of having
    come from the same place. We achieve this by learning a generative
    model of place appearance. By partitioning the learning problem into
    two parts, new place models can be learned online from only a single
    observation of a place. The algorithm complexity is linear in the
    number of places in the map, and is particularly suitable for online
    loop closure detection in mobile robotics.},
