摘要： A power meter generates a time series of observations of power drawn by a device configured to operate in an active mode and to transition through a sequence of inactive modes comprising one or more intermediate inactive modes each having a bounded time duration terminating in a final inactive mode of unbounded time duration, and further configured to transition from any of the inactive modes to the active mode in response to a device activation signal. An electronic data processing device is programmed to determine statistical characteristics of the power draw of the device in each of the inactive modes by fitting a state model to the time series of observations. The state model represents each intermediate inactive mode including its bounded time duration and further includes a probabilistic representation of the transition from any of the inactive modes to the active mode in response to a device activation signal.

摘要： A method for inferring user activity statistics includes receiving job logs of a device infrastructure. Each job log including job information for a job performed for one of a set of users by one of a plurality of shared devices. A job descriptor is generated for each job based on the job log. The job is assigned to one of a set of defined job types based on the job descriptor. An activity matrix is composed where activity of each user for each of a plurality of time periods is represented as a fixed-length vector representing at least some of the job types. Each index of the vector is derived from a count of one job type for the user in that time period. The activity matrix is decomposed into first and second factor matrices to minimize an overall reconstruction error. User activity statistics are output based on the decomposition.

摘要： A system and method predict the translation quality of a translated input document. The method includes receiving an input document pair composed of a plurality of sentence pairs, each sentence pair including a source sentence in a source language and a machine translation of the source language sentence to a target language sentence. For each of the sentence pairs, a representation of the sentence pair is generated, based on a set of features extracted for the sentence pair. Using a generative model, a representation of the input document pair is generated, based on the sentence pair representations. A translation quality of the translated input document is computed, based on the representation of the input document pair.

摘要： Methods and systems input an energy consumption profile for each of a plurality of different sleep modes available for a device, and input a probability distribution of interjob times for the device. The methods and systems then compute the optimal time-out period for each sleep mode based on the energy consumption profile of each sleep mode and the probability distribution of interjob times. Further, such methods and systems monitor the usage of the device to determine the current interjob time, and switch between sleep modes to relatively lower power sleep modes as the current interjob time becomes larger.
