Abstract: A method, computer program product, and computer system for predicting responses to at least one conversational phrase. At least one conversational phrase may be received. A first probability for a subset of candidate responses of a plurality of candidate responses may be determined based upon, at least in part, context associated with the at least one conversational phrase, the at least one conversational phrase, and each context associated with the plurality of candidate responses. A second probability for the subset of candidate responses may be determined based upon, at least in part, the subset of candidate responses, the at least one conversational phrase, and the context associated with the at least one conversational phrase. At least one candidate response for the at least one conversational phrase may be determined based upon, at least in part, the first probability and the second probability.

Abstract: An exemplary parallel hybrid power filter apparatus for the electrified railway is described. The apparatus may include a group of LC reactive filter being purely tuned, an additional inductance, an active power filter and a coupling transformer. The active power filter may be controlled, e.g., as a current source in a composite control manner and can be connected in parallel to the additional inductance via the coupling transformer. The power filter can be connected to the reactive filter in series to form the parallel hybrid filtering system, and may be connected to the power grid via the circuit breaker or a thyristor. This exemplary system can be installed either in the traction substations or in the locomotives directly, or performed by ameliorating the original reactive filter. The active power filter does not add significant amount of cost, and may be simple and reliable in a control manner for the capacity of the APF is so small as to be less than one percent of that of the harmonics source.
