Patents by Inventor Abdel-rahman Samir Abdel-rahman Mohamed

Abdel-rahman Samir Abdel-rahman Mohamed has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9734824
    Abstract: A system and method for applying a convolutional neural network (CNN) to speech recognition. The CNN may provide input to a hidden Markov model and has at least one pair of a convolution layer and a pooling layer. The CNN operates along the frequency axis. The CNN has units that operate upon one or more local frequency bands of an acoustic signal. The CNN mitigates acoustic variation.
    Type: Grant
    Filed: May 25, 2015
    Date of Patent: August 15, 2017
    Assignees: THE GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTO

  • Patent number: 9031844
    Abstract: A method includes an act of causing a processor to access a deep-structured model retained in a computer-readable medium, the deep-structured model includes a plurality of layers with respective weights assigned to the plurality of layers, transition probabilities between states, and language model scores. The method further includes the act of jointly substantially optimizing the weights, the transition probabilities, and the language model scores of the deep-structured model using the optimization criterion based on a sequence rather than a set of unrelated frames.
