Claim 12:
13. A system comprising:
a camera configured to generate image data representing a first inventory location;
a weight sensor configured to generate weight data associated with the first inventory location;
one or more processors; and
one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to:
determine, using the image data, a first hypothesis of a first event, the first event representing a first occurrence of a user handling a first item during a time period in a facility the first event being determined based at least in part on the image data representing the user handling the first item;
determine, using the weight data, a second hypothesis of a second event, the second event representing a second occurrence of the user handling a second item during the time period in the facility, the second event being determined based at least in part on a change in the weight data corresponding to a weight of the second item;
generate a first probabilistic listing of items taken by the user during the time period, the first probabilistic listing including:
a first probability value indicating a first likelihood that the first item was taken by the user from the facility; and
a second probability value indicating a second likelihood that the second item was taken by the user from the facility;

determine that at least one of the first probability value or the second probability value is less than a threshold;
determine that resolving the first event is more likely to increase an overall probability value for the first probabilistic listing of items than resolving the second event;
determine, using an algorithm, a third hypothesis of the first event associated with the first item, wherein to determine the third hypothesis includes:
identifying a third event occurring during the time period that is related to the first event; and
determining an overall result of at least the first event and third event;

based at least in part on the third hypothesis of the first event, generate a second probabilistic listing of items taken by the user during the time period;
determine that one or more probabilistic values included in the second probabilistic listing of items are greater than or equal to the threshold; and
store an association between the second probabilistic listing of items and an account of the user.
