  • Publication number: 20200163568
    Abstract: Metacognitive confidence is defined as the confidence generated from the observation and critical analysis of one's own the decision making process. There are various studies indicative of the importance of measurement of confidence level of the person while doing a task. The existing confidence level measurement methods provide various limitations such invasive and complex experimental setup, noise and artifacts in the signal. A system and method for determining confidence level of a person using electroencephalogram has been provided. The system is configured to build a metric to determine the amount of metacognitive confidence, in presence of different cognitive load condition, directly from brain activity using electroencephalogram signals. The brain activity acquired from the frontal and temporal part of the brain at different frequency bands and combined with suitable weights to form the confidence metric.

  • Patent number: 10628738
    Abstract: Method, system, and apparatus for automatic stance classification. Propositions can be collected that are relevant to a query. A classifier can classify the stance of each proposition based on whether the proposition supports the query, opposes the query, or is neutral with respect to the query in order to thereafter provide substantive data for decision making based on and extracted from the query. The stance can be classified based on, for example, an SVM-SC (SVM Based Stance Classification) approach and/or an NN-SC (Neural Network Stance Classification Approach).

  • Patent number: 10445089
    Abstract: A method and apparatus of a network element that hitlessly upgrades a network element operating system of a network element is described. In an exemplary embodiment, the network element hitlessly upgrades the network element operating system by instantiating a second container and starts a second set of processes using a second image of the network element operating system in the second container. In addition, the network element executes a first image of the network element operating system as a first set of processes in a first container. The network element additionally synchronizes state data between the first set of processes and the second set of processes. Furthermore, the network element sets the second set of processes as managing a plurality of hardware tables, and stops the first set of processes within the first container.

  • Patent number: 10420527
    Abstract: System and method for determining a heart rate and a heart rate variability of an individual is disclosed. An audio signal of heart sound is amplified. Subsequently, an envelope of the amplified audio signal is detected by squaring of the amplified audio signal to obtain emphasized high amplitude components and diminished low amplitude components of the audio signal, applying a band pass filter on the audio signal upon squaring and applying a Teager-Kaiser Energy Operator (TKEO) on the filtered audio signal. Peaks in the envelope of the audio signal are detected by calculating difference in magnitude of a point in the audio signal with an average of magnitude of earlier points in the audio signal from the last detected peak or the initial sample value in the processing window when no peak is detected. Based on the peaks detected, heart rate and heart rate variability for the individual are determined.

  • Patent number: 10394958
    Abstract: A method and system for performing semantic analysis for electronic communication using a lexicon is provided. A neural network model is trained with a plurality of annotated text strings, the annotations comprising characteristic tuples that indicate characteristics for the text strings. An unannotated text string is received that comprises a plurality of words from a user. A characteristic matrix for the received text string is generated using a lexicon. The determined characteristic matrix is input into the trained neural network. And a characteristic tuple that indicates a characteristic for the received text string is received as output from the trained neural network.

  • Publication number: 20180248769
    Abstract: A method and apparatus of a device that simulates a plurality of network elements is described. In an exemplary embodiment, the device receives network topology information for the plurality of simulated network elements. The device further instantiates a container for each of the plurality of simulated network elements. The device additionally configures a set of processes for each of the plurality of containers, where each of the set of processes simulates at least one of the plurality of simulated network elements. The plurality of set of processes further implements a network topology represented by the network topology information. The device performs a test of the network topology and saves the results of the test.

  • Patent number: 9703582
    Abstract: A method or network system able to efficiently redistribute information, data, and/or context between virtual machines (“VMs”) using an in-memory file system (“IMFS”) is disclosed. After requesting memory access by an application program, a process of VM using IMFS is able to forward the memory allocation request from a VM kernel operating under a VM environment to an emulator. The emulator, which operates between the VM kernel and the hypervisor, again redirects the memory allocation request to the hypervisor for storage allocation. The hypervisor subsequently allocates at least a portion of storage space in the IMFS in accordance with the memory allocation request.
