  • Patent number: 9418343
    Abstract: Implementations of the disclosed subject matter provide methods and systems for using a multistage learner for efficiently boosting large datasets in a machine learning system. A method may include obtaining a first plurality of examples for a machine learning system and selecting a first point in time. Next, a second point in time occurring subsequent to the first point in time may be selected. The machine learning system may be trained using m of the first plurality of examples. Each of the m examples may include a feature initially occurring after the second point in time. In addition, the machine learning system may be trained using n of the first plurality of examples, and each of the n examples may include a feature initially occurring after the first point in time.

  • Publication number: 20160234208
    Abstract: Embodiments are provided for mutually authenticating a pair of electronic devices. According to certain aspects, the electronic devices may connect to each other via an out-of-band communication channel. The electronic devices may each output audio signals and detect audio signals output by the other electronic devices. Based on timestamps associated with audio output and detection events, each of the electronic devices may calculate relevant time and distance parameters, and transmit the calculated parameters to the other electronic device via the out-of-band communication channel. The electronic devices may compare the calculated parameters to determine mutual authentication.

  • Patent number: 9391206
    Abstract: Some embodiments include methods of forming transistors. Recesses are formed to extend into semiconductor material. The recesses have upper regions lined with liner material and have segments of semiconductor material exposed along lower regions. Semiconductor material is isotropically etched through the exposed segments which transforms the recesses into openings having wide lower regions beneath narrow upper regions. Gate dielectric material is formed along sidewalls of the openings. Gate material is formed within the openings and over regions of the semiconductor material between the openings. Insulative material is formed down the center of each opening and entirely through the gate material. A segment of gate material extends from one of the openings to the other, and wraps around a pillar of the semiconductor material between the openings. The segment is a gate of a transistor. Source/drain regions are formed on opposing sides of the gate.

  • Patent number: 9390382
    Abstract: Systems and techniques are disclosed for training a machine learning model based on one or more regularization penalties associated with one or more features. A template having a lower regularization penalty may be given preference over a template having a higher regularization penalty. A regularization penalty may be determined based on domain knowledge. A restrictive regularization penalty may be assigned to a template based on determining that a template occurrence is below a stability threshold and may be modified if the template occurrence meets or exceeds the stability threshold.

  • Publication number: 20160162900
    Abstract: A system for authentication for a user device associated with a user, said system comprising: a processing system to generate a first user interface running on a screen of said user device, said first user interface comprising one or more components, wherein said one or more components comprises a first icon, which when activated, directs a user to a second user interface to select a secret pattern, a second icon, which when activated, generates a current randomly populated keyboard, further wherein said processing system provides a current Personal Identification Number (PIN) to said user by correlating said secret pattern with the current randomly populated keyboard, and a regular keyboard for said user to enter a PIN for authentication.

  • Patent number: 9319778
    Abstract: In a first example of “Body-Area Networking” (“BAN”), a user wishing to access his electronic device ingests a small pill carrying a transmitter. The transmitter's signal carries an identification code that traverses the user's BAN and is read by the device. If the device recognizes that identification code as authenticate, then the device grants the user the desired access. In another example, the user again swallows a transmitter. When the user shakes hands with another person, the signal originating at the ingested transmitter is carried across the BAN of the first user, travels across the handshake to the BAN of the second user, then traverses the second user's BAN to her device. In a third example, a media player transmits audio information across the BAN to a headset worn by the user. The headset receives the signal, demodulates it, and renders the audio to the user.

  • Publication number: 20160057623
    Abstract: A system for implicit authentication for a mobile device associated with a user, wherein the implicit authentication is behavioural, biometric and task-based and includes at least one authentication task selected so as to leverage the user's muscle memory. The mobile device comprises a touchscreen; a transaction authentication information unit; one or more sensors coupled to the transaction authentication information unit; and an anomaly detector coupled to the transaction authentication information unit. The sensors comprise one or more touchscreen sensors coupled to the touchscreen, an accelerometer, and a gyroscope, and are used to obtain and transmit one or more sets of data to the transaction authentication information unit. The sets of data are associated with one or more performances of the authentication task by the user. The anomaly detector generates an authentication model using the one or more data sets transmitted to the transaction authentication information unit.

  • Patent number: 9269057
    Abstract: Systems and techniques are disclosed for generating weighted machine learned models using multi-shard combiners. A learner in a machine learning system may receive labeled positive and negative examples and workers within the learner may be configured to receive either positive or negative examples.

  • Publication number: 20160034675
    Abstract: Authenticating users comprises a computing device that receives a manual authentication input of a user and initiates a first user session between the user and the user computing device. The device communicates a request for a first user authorization data from an authentication technology associated with the one or more computing devices and receives the first user authentication data. The user or the device terminates the first user session and subsequently receives an input of the user to initiate a second user session. The device communicates a request for second user authentication data from the authentication technology and compares the first user authentication data and the second user authentication data. The device identifies a match of one or more features of the first user authentication data and one or more features of the second user authentication data and authorizes the user to conduct the second user session.
