Abstract: Systems, methods and computer-readable medium for (i) accelerating the inference speed of a deep neural network (DNN), and (ii) compressing the vector representations produced by the DNN out of a variety of input data, such as image, audio, video and text. A method embodiment takes as inputs a neural network architecture and a task-dependent loss function, measuring how well a neural network performs on a training data set, and outputs a deep neural network with sparse neuron activations. The invented procedure augments an existing training objective function of a DNN with regularization terms that encourage sparse activation of neurons, and compresses the DNN by solving the optimization problem with a variety of algorithms. The present disclosure also shows how to utilize the sparsity of activations during the inference of DNNs so the number of arithmetic operations can be reduced proportionately, and how to use the sparse representations produced by the DNNs to build an efficient search engine.

IPC: A62B18/02
Filed: 2019-10-18
Abstract: A facial mask includes a foam sealer that is attached at one or more sides of the mask. The foam sealer prevents air or breath from going upwards out of the mask, thereby preventing glasses from being fogged up during surgery. It also keeps air or materials from getting into the mask and prevents, to a degree, bodily fluids and unwanted odors from penetrating the mask than existing masks. The mask prevents unwanted distractions to the surgeon or other medical personnel. The mask also may prevent medical illnesses from the inhalation of air, the exposure to bodily fluids, or the transfer of gases. The foam sealer is comprised of open cell foam. The facial mask acts as a more complete barrier to odors and bodily fluids that may otherwise endanger both the user or other personnel. The decreases in fogging of glasses also will make use of the facial mask safer than normal masks because of increased visibility during surgery or other procedures.
