    摘要： A machine accesses a preexisting set of natural language text documents in multiple natural languages. Each natural language text document in at least a portion of the preexisting set is associated with an event. The machine trains, using the preexisting set of natural language text documents and the associated events, an event encoder to learn associations between texts and event annotations. The event encoder leverages a parser in each of the two or more natural languages. The machine generates, using the event encoder, new event annotations for texts. The machine trains, using the preexisting set of natural language text documents and the new event annotations for the texts generated by the event encoder, an event extraction engine to extract events from natural language texts in the two or more natural languages. The event extraction engine leverages the parser in each of the two or more natural languages.

    摘要： Techniques are described herein for a messaging system to allow publishers that are aware of the identities of their respective subscribers to target content at those subscribers directly. This may be accomplished by allowing users and other targets (e.g., groups) to register their identities at particular computing nodes of a system. Then publishers (e.g., applications) may send out messages targeted at particular identities, and a publishing system may forward messages to appropriate nodes based on which identities are registered at those nodes. Legacy applications that are not able to target particular identities may instead connect to application adapters that are configured to learn which identities should be targeted by each application. In addition, anonymized identities may be used for application messages that need to cross between domains having differing security levels.

    摘要： A receiver for cancelling strong signals from combined weak and strong signals includes: a first circuitry for inputting a weak and strong signal as an input; a parametric cancellation circuit for inputting a representation of the strong signal and an output of the first circuitry to produce a cancellation signal; a second circuitry electrically coupled to the parametric cancellation circuit for inputting the cancellation signal to produce a modulated output; a demodulator electronically coupled to the second circuitry for demodulating the modulated output to produce a demodulated output and an error signal, where the demodulated output is the data contained in the weak signal; and an adaptation logic circuit for inputting the representation of the strong signal, the demodulated output and the error signal to adaptively produce parameters for the parametric cancellation circuit. The parametric cancellation circuit further inputs the error signal and the parameters to produce the cancellation signal.

    摘要： An optical circuit for estimating separation distances between N image sources includes an aperture for receiving N light beams and producing a point spread function specific to a symmetry of the image sources from the plurality of light beams; first optical phase shifters to shift the quantum state modes of (N-1) light beams by ɯNN; first beamsplitters, each for mixing respective pairs of quantum state modes of outputs of the first optical phase shifters for a quantum superposition of the respective pairs of the quantum state modes; second beamsplitters, each for mixing respective outputs of the first beamsplitters alternatively; second phase shifters to further shift outputs of the second beamsplitters; N detectors for converting each of the received N light beams to an analog signal; and a signal processing circuit for performing signal processing on the analog signals to estimate the separation distances.

    摘要： Method for estimating separation distances between a plurality of image sources in a multi-point source imaging system includes: receiving a plurality of light beams, each from a respective image source and having a quantum state mode; constructing a point spread function (PSF) for light beams specific to a symmetry of the image sources; calculating a quantum Fourier transform on the quantum state mode of the plurality of light beams that achieves a quantum limit in a paraxial approximation regime to estimate separation of image sources at the quantum limit to transform the light beams; detecting the transformed light beams to generate electrical signals from respective transformed light beams; and performing signal processing on the electrical signals to estimate the separation distances between the plurality of image sources.
