Conventional techniques for automatically evaluating and grading assignments are generally ill-suited to evaluation of coursework submitted in media-rich form. For courses whose subject includes programming, signal processing or other functionally expressed designs that operate on, or are used to produce media content, conventional techniques are also ill-suited. It has been discovered that media-rich, indeed even expressive, content can be accommodated as, or as derivatives of, coursework submissions using feature extraction and machine learning techniques. Accordingly, in on-line course offerings, even large numbers of students and student submissions may be accommodated in a scalable and uniform grading or scoring scheme. Instructors or curriculum designers may adaptively refine assignments or testing based on classifier feedback. Using developed techniques, it is possible to administer courses and automatically grade submitted work that takes the form of media encodings of artistic expression, computer programming and even signal processing to be applied to media content.

Systems and methods for or training as sequence tagger, such as conditional random field model. More specifically, the systems and methods train a sequence tagger utilizing partially labeled data from crowd-sourced data for a specific application and partially labeled data from search logs. Further, the systems and methods disclosed herein train a sequence tagger utilizing only partially labeled by utilizing a constrained lattice where each input value within the constrained lattice can have multiple candidate tags with confidence scores. Accordingly, the systems and methods provide for a more accurate sequence tagging system, a more reliable sequence tagging system, and a more efficient sequence tagging system in comparison to sequence taggers trained utilizing at least some fully-labeled training data.

Using the short form information people tend to use in their calendar locations (not full address or GPS location), machine learning techniques are used to map gathered location information to these short form names.

Disclosed are various embodiments for using media reported events to generate predictions for time series data. Information retrieved from a plurality of network content sources is classified into a plurality of categories. A prediction is generated for a time series. The time series is associated with a metric observed in a computing system. The generated prediction takes into account an impact of at least one of instance of the classified information.

A liquid state machine pulse domain neural processor circuit comprising an asynchronous input filter circuit provided for, at any given time, receiving a series of analog input signals and generating in response a set of time-encoded values that depend on the series of analog input signals received at said given time and before said given time; and an asynchronous trainable readout map circuit for transforming at least a portion of said set of time encoded values into output signals.

Systems and methods are provided for providing an ordered list of search results in response to a query. Consistent with certain embodiments, computer-implemented systems and methods may identify content items corresponding to a query. First relevance scores may be determined for the identified content items based on their relevance to the query. Second relevance scores may be determined by modifying at least one of the first relevance scores using a boost value. The boost value may be set to a default boost value when the query does not include an override boost value. The boost value may be set to the override boost value, when the query includes an override boost value. An ordered list of the identified content items may be generated based on the second relevance scores. The ordered list may be displayed on a display device.

A method includes, based on a fitness function, selecting a subset of models from a plurality of models. The plurality of models is generated based on a genetic algorithm and corresponds to a first epoch of the genetic algorithm. Each of the plurality of models includes data representative of a neural network. The method also includes performing at least one genetic operation of the genetic algorithm with respect to at least one model of the subset to generate a trainable model and sending the trainable model to an optimization trainer. The method includes adding a trained model received from the optimization trainer as input to a second epoch of the genetic algorithm that is subsequent to the first epoch.

A system, method and computer program product for achieving a collective task. The system comprises a plurality of elements representative of a first hierarchy level, each element comprises a plurality of sub-elements. The system comprises also an arbitration module for selecting one of the sub-elements of each element at a point in time based on a global clock, wherein each sub-element relates to one list element of an ordered circular list, and a combination module adapted for a combination of sub-actions performed by a portion of the sub-elements of one of the elements over a predefined period of time, wherein each sub-element performs one of the sub-actions.

A computer-implemented method of determining search intent, comprises: receiving a search query; searching content across a plurality of content classes using the search query, so as to obtain a plurality of search results; deriving summary data from the search results; applying the summary data to a trained machine learning model; and determining from the machine learning model a selected one of the content classes corresponding to the search intent of the search query.

Deep learning is used to identify specific, potential entertainment risks to an enterprise while such risks before the enterprise commits large sums of money to a project. The system involves mining and using existing classifications of data (e.g., from a database of previously successful book and film franchises) to train one or more deep learning algorithms, and then examining a proposed entertainment document with the trained algorithm, to generate a scored output that will enable enterprise personnel to be alerted to risks and take action in time to prevent the risks from resulting in harm to the enterprise.
