  • Patent number: 10534839
    Abstract: A method for matrix by vector multiplication, applied in an artificial neural network system, is disclosed. The method comprises: compressing a plurality of weight values in a weight matrix and indices of an input vector into a compressed main stream; storing M sets of synapse values in M memory devices; and, performing reading and MAC operations according to the M sets of synapse values and the compressed main stream to obtain a number M of output vectors. The step of compressing comprises: dividing the weight matrix into a plurality of N×L blocks; converting entries of a target block and corresponding indices of the input vector into a working block and an index matrix; removing zero entries in the working block; shifting non-zero entries row-by-row to one of their left and right sides in the working block; and, respectively shifting corresponding entries in the index matrix.

  • Publication number: 20190183960
    Abstract: The present invention provides a method to treat asthma and airway allergy by administering the dipeptide cyclo tyrosine-valine or a related cyclodipeptide compound to a subject in need thereof. Cyclo tyrosine-valine or the related cyclodipeptide compound reduces Th2 cell activation, airway hyperresponsiveness, accumulation of immune cells in bronchoalveolar fluid, and allergen-specific antibody production in an animal or human subject. The compound can therefore be used to treat asthma and airway allergy.

  • Patent number: 10182283
    Abstract: A noise cancellation device includes an anti-noise filter circuit, an output circuit, and a detection circuit. The anti-noise filter circuit provides a corresponding one of transfer functions to process a digital signal, in order to generate a noise cancellation signal, in which the transfer functions are different from each other. The output circuit mixes the noise cancellation signal, a reference signal, and an input signal to generate a mixed signal, and generates a sound output signal based on the mixed signal, in which the digital signal is associated with the sound output signal. The detection circuit controls the anti-noise filter circuit to provide the corresponding one of the transfer functions according to a comparison result of a first ratio and a first threshold value, in which the first ratio is a ratio of a first power of the mixed signal to a second power of the digital signal.
