  • Publication number: 20140358523
    Abstract: One or more embodiments of techniques or systems for sentiment extraction are provided herein. From a corpus or group of social media data which includes one or more expressions pertaining to a topic, target topic, or a target, one or more candidate expressions may be extracted. Relationships between one or more pairs of candidate expressions may be identified or evaluated. For example, a consistency relationship or an inconsistency relationship between a pair may be determined. A root word database may include one or more root words which facilitate identification of candidate expressions. Among one or more of the root words may be seed words, which may be associated with a predetermined polarity. To this end, polarities may be determined based on a formulation which assigns polarities to a sentiment expression, candidate expressions, or an expression as a constrained optimization problem.

  • Publication number: 20140195475
    Abstract: Embodiments of this invention comprise modeling a subject's state and the influence of training treatments, or actions, on that state to create a training policy. Both state and effects of actions are modeled as probabilistic using Partially Observable Markov Decision Process (POMDP) techniques. Utilizing this model and the resulting training policy with subjects creates an effective decision aid for instructors to improve learning relative to a traditional scenario selection strategy.

  • Patent number: 8655822
    Abstract: Embodiments of this invention comprise modeling a subject's state and the influence of training scenarios, or actions, on that state to create a training policy. Both state and effects of actions are modeled as probabilistic using Partially Observable Markov Decision Process (POMDP) techniques. The POMDP is well suited to decision-theoretic planning under uncertainty. Utilizing this model and the resulting training policy with real world subjects creates a surprisingly effective decision aid for instructors to improve learning relative to a traditional scenario selection strategy. POMDP provides a more valid representation of trainee state and training effects, thus it is capable of producing more valid recommendations concerning how to structure training to subjects.

  • Publication number: 20130325436
    Abstract: A composite language model may include a composite word predictor. The composite word predictor may include a first language model and a second language model that are combined according to a directed Markov random field. The composite word predictor can predict a next word based upon a first set of contexts and a second set of contexts. The first language model may include a first word predictor that is dependent upon the first set of contexts. The second language model may include a second word predictor that is dependent upon the second set of contexts. Composite model parameters can be determined by multiple iterations of a convergent N-best list approximate Expectation-Maximization algorithm and a follow-up Expectation-Maximization algorithm applied in sequence, wherein the convergent N-best list approximate Expectation-Maximization algorithm and the follow-up Expectation-Maximization algorithm extracts the first set of contexts and the second set of contexts from a training corpus.

  • Patent number: 8553835
    Abstract: A computed tomography scanner may include a component mounting assembly, an x-ray tube, a filter assembly, and a detector assembly. The filter assembly filters an x-ray fan or cone beam generated by the x-ray tube such that the x-ray beam comprises a high dose portion and one or more low dose portions. The filter assembly reduces the photon count of the low dose portions. The x-ray tube may be coupled to the component mounting assembly at a first end and the detector assembly coupled at a second end that is opposite from the first end. The component mounting assembly is rotatable about a rotation axis. The detector assembly includes an array of individual detector elements capable of detecting x-ray photons of the x-ray beam. The high dose portion strikes a high resolution region of the detector assembly and the low dose portion strikes a low resolution region of the detector assembly.
