  • Publication number: 20180322642
    Abstract: Described is a system for predicting multi-agent movements. A Radon Cumulative Distribution Transform (Radon-CDT) is applied to pairs of signature-formations representing agent movements. Canonical correlation analysis (CCA) components are identified for the pairs of signature-formations. Then, a relationship between the pairs of signature formations is learned using the CCA components. A counter signature-formation for a new dataset is predicted using the learned relationship and a new signature-formation. Control parameters of a device can be adjusted based on the predicted counter signature-formation.

  • Publication number: 20180217603
    Abstract: A system and method is taught for data processing where an environment around the self-vehicle is encoded into ego centric and geocentric overlapping coordinate systems. The overlapping coordinate systems are then divided into adaptively sized grid cells according to characteristics of environments and the self-vehicle status. Each grid cell is defined with one of representative event patterns and risk values to the self-vehicle. The autonomous driving system is then operative to provide a real time assessment of the surrounding environment in response to the grid cell data. And temporal sequences of the grid cell data are stored in the episodic memory and recalled from it during driving.

  • Patent number: 9824607
    Abstract: A brain-machine interface for extracting user action intentions within a continuous asynchronous interactive environment is presented. A subliminal stimulus module generates contextually appropriate decision-related stimuli that are unobtrusive to a user. An altered perceptual experience module modifies a user's sensation of the interactive environment based on decision-related stimuli generated from the subliminal stimulus module. A brain monitoring module assesses the user's brain activity in response to the decision-related stimuli and to determine whether an action within the asynchronous interactive environment is intended by the user. Finally, an action is taken based on explicit user input, the user's brain activity in response to the decision-related stimuli, or a combination thereof.

  • Publication number: 20170316265
    Abstract: Described is a system for feature selection for formal concept analysis (FCA). A set of data points having features is separated into object classes. For each object class, the data points are convolved with a Gaussian function, resulting in a class distribution curve for each known object class. For each class distribution curve, a binary array is generated having ones on intervals of data values on which the class distribution curve is maximum with respect to all other class distribution curves, and zeroes elsewhere. For each object class, a binary class curve indicating for which interval a performance of the known object class exceeds all other known object classes is generated. The intervals are ranked with respect to a predetermined confidence threshold value. The ranking of the intervals is used to select which features to extract from the set of data points in FCA lattice construction.

  • Patent number: 9646056
    Abstract: Described is a system for rank-ordered and cognitive saliency schema-based object selection. The system receives a set of unnormalized probabilities corresponding to a set of objects competing for attentional selection in a current environment. Each unnormalized probability in the set of unnormalized probabilities is based on a likelihood estimation of encountering the corresponding object in the current environment. The set of objects is ranked based on a set of cognitive saliency values corresponding to the set of objects to generate a rank-ordered list of cognitive saliency values. The rank-ordered list of cognitive saliency values is analyzed to detect a schema of the current environment by which the set of objects is ranked. The schema is learned and stored along with a reward measure of the schema's utility. A maximum saliency object in the set of objects is selected based on the rank-ordered list of cognitive saliency values.

  • Patent number: 9552544
    Abstract: Described is a system for action selection based on a combination of neuromodulatory and prefrontal cortex models. The system inputs group attack probability estimates for multiple groups in a prefrontal cortex (PFC) input area of a model instance. The system encodes a dispersion of the group attack probability estimates in an anterior cingulated cortex (ACC) conflict input area of the model instance, resulting in activation of the ACC conflict input area. The activation is propagated to an action area and a neuromodulatory area of the model instance. An action strategy is selected in the action area. The action strategy is implemented, and a reward and a cost is generated for the implemented action strategy. An assessment of possible action strategies is updated based on the generated reward and cost. Each model instance modulates its subsequent action strategy selection based on the updated assessment of the possible action strategies.

  • Patent number: 9269027
    Abstract: Described is a system for optimizing rapid serial visual presentation (RSVP). A similarity metric is computed for RSVP images, and the images are sequenced according to the similarity metrics. The sequenced images are presented to a user, and neural signals are received to detect a P300 signal. A neural score for each image is computed, and the system is optimized to model the neural scores. The images are resequenced according a predictive model to output a sequence prediction which does not cause a false P300 signal. Additionally, the present invention describes computing a set of motion surprise maps from image chips. The image chips are labeled as static or moving and prepared into RSVP datasets. Neural signals are recorded in response to the RSVP datasets, and an EEG score is computed from the neural signals. Each image chip is then classified as containing or not containing an item of interest.

  • Patent number: 9002762
    Abstract: Described is a system for adaptive memory recall. The system receives original input data, then divides the original input data into multiple data groups to serve as input for a network comprising a pattern separation layer and an autoassociative memory layer. The original input data is processed with a pattern separation component of the pattern separation layer, and each pattern separation component generates an increased-contrast version of the original input data it processes. The generated increased-contrast version of the original input data is combined with the original input data and stored in an autoassociative memory component of the autoassociative memory layer for each data group. New input data is received, and a parameter that controls processing in the pattern separation layer is modulated to determine an optimal parameter, which indicates that a memory recall between the stored data and the new set of input data is achieved.

  • Patent number: 8990139
    Abstract: Described is a system for flexible cognitive perception and selection. A pre-processing recognition module filters and tags input data from an environment resulting in a tagged percept. The tagged percept is stored and associated with a knowledge frame by a memory module based on shared descriptors, resulting in an activated knowledge frame. A utility rating is then supplied to each activated knowledge frame based on a set of reward values by an evaluation module. The activated knowledge frames are sorted, compared, and evaluated for a goodness of fit between the utility ratings of the activated knowledge frames and the input data by a hypothesis module. A best hypothesis for a current situation in the environment is determined based on a current highest rated activated knowledge frame.
