Abstract
At least one activity history for a plurality of entities is received. The at least one activity history comprises at least two events. An inter-event gap distribution is learned using the at least one activity history for the plurality of entities. A current activity history for a current entity is received. A probability of at least one of an onset and a termination related to the current activity history is determined based on the learned inter-gap distribution. An output is produced based on the determined probability.
Claims20
A method, comprising:
- receiving at least one activity history for a plurality of entities, the at least one activity history comprising at least two events;
- learning an inter-event gap distribution using the at least one activity history for the plurality of entities;
- receiving a current activity history for a current entity;
- determining a probability of at least one of an onset and a termination related to the current activity history based on the learned inter-gap distribution;
- and
- producing an output based on the determined probability.
A system comprising:
- a processor;
- and
- a memory storing computer program instructions which when executed by the processor cause the processor to perform operations comprising:
- receiving at least one activity history for a plurality of entities, the at least one activity history comprising at least two events;
- learning an inter-event gap distribution using the at least one activity history for the plurality of entities;
- receiving a current activity history for a current entity;
- determining a probability of at least one of an onset and a termination related to the current activity history based on the learned inter-gap distribution;
- and
- producing an output based on the determined probability.
A non-transitory computer readable medium storing computer program instructions for determining an answer to a question in a multi-party conversation, the computer program instructions when executed by a processor cause the processor to perform operations comprising:
- receiving at least one activity history for a plurality of entities, the at least one activity history comprising at least two events;
- learning an inter-event gap distribution using the at least one activity history for the plurality of entities;
- receiving a current activity history for a current entity;
- determining a probability of at least one of an onset and a termination related to the current activity history based on the learned inter-gap distribution;
- and
- producing an output based on the determined probability.
