Abstract: Systems and methods of related to a voice-based system used to determine the severity of emotional distress within an audio recording of an individual is provided. In one non-limiting example, a system comprises a computing device that is configured to receive an audio sample that includes an utterance of a user. Feature extraction is performed on the audio sample to extract a plurality of acoustic emotion features using a base model. Emotion level predictions are generated for an emotion type based at least in part on the acoustic emotion features provided to an emotion specific model. An emotion classification for the audio sample is determined based on the emotion level predictions. The emotion classification comprises the emotion type and a level associated with the emotion type.

Abstract: Some embodiments provide a method for defining a content relevance model for determining whether a content segment is relevant to a particular category. The method receives a first set of content segments that contain content relevant to the particular category and a second set of content segments that contain content not relevant to the particular category. The method identifies a set of key word sets more likely to appear in the first set of content segments than the second set of content segments. The method defines a content relevance model that comprises a set of groups of word sets and a score for each group, each of the groups of word sets comprising a key word set from the set of key word sets and at least one word set found in a context of the key word set in at least one of the received content segments.

Abstract: An electrical machine assembly includes a stator. The stator includes a core, windings assembled into the core, and a back iron heat exchanger mounted to the core. A first end plate is mounted at a first end of the core and back iron heat exchanger. A second end plate is mounted at a second end of the core and back iron heat exchanger opposite the first end plate. A coolant circuit passes from a coolant inlet in the back iron heat exchanger, through the back iron heat exchanger, into the first end plate, out of the first end plate, through the core, into the second end plate, and out of the second end plate.

Abstract: A wedge for a wound rotor includes a wedge body. The wedge body has a first layer and one or more second layers interfused with one another to provide structural support and limit resistive heating of the wedge from current flow within the wedge body by windings spaced apart by the rotor wedge.

Abstract: To measure usage of computing resources on a computer, a logging service running on the computer generates event data. The computer transmits the event data to an event processing system. With a large number of computers, each computer transmits its event data to the event processing system. The event processing system stores the event data in a storage system as a file system object, such as a stream or file, in which different data fields of the received event data are stored in a structured or semi-structured manner. The event data can be processed in parallel on different pivots using map-reduce operations. Such processing can include, but is not limited to, de-duplicating event data, aggregating event data related to a resource into measurements of usage of that resource, and grouping original data or aggregated data by user or group of user for further analysis and reporting.

Abstract: Some embodiments provide a method for determining a relatedness of content items to categories. The method identifies a particular content item, a relevancy score associated with the particular content item, and a set of categories to which the particular content item is classified as related. Based on a set of glossaries associated with the set of categories, the method calculates a set of affinity scores that each represents a degree of relevancy between the particular content item and a category in the set of categories. The method modifies the relevancy score associated with the particular content item based on the calculated set of affinity scores.

Abstract: Some embodiments provide a program that identifies an entity having an entity attribute. The program receives, from each method of several methods, a set of candidate identity attributes that are each for identifying a particular entity having the entity attribute specified in the document. Each method of the several methods generates the corresponding set of candidate identity attributes based on the entity attribute specified in a document. The program calculates a score for each candidate identity attribute in the sets of candidate identity attributes. The program identifies, based on the sets of scores, an identity attribute from the sets of candidate identity attributes that identifies the entity having the entity attribute specified in the document.
