Publication number: 20220327386Abstract: The present disclosure describes neural network reduction techniques for decreasing the number of neurons or layers in a neural network. Embodiments of the method, apparatus, non-transitory computer readable medium, and system are configured to receive a trained neural network and replace certain non-linear activation units with an identity function. Next, linear blocks may then be folded to form a single block in places where the non-linear activation units were replaced by an identity function. Such techniques may reduce the number of layers in the neural network, which may optimize power and computation efficiency of the neural network architecture (e.g., without unduly influencing the accuracy of the network model).Type: ApplicationFiled: August 11, 2021Publication date: October 13, 2022Inventors: Amir Ben-dror, Niv Zehngut, Evgeny Artyomov, Ran Vitek, Sapir Kaplan

Publication number: 20220147680Abstract: Methods, systems, and apparatus for combined or separate implementation of coarse-to-fine neural architecture search (NAS), two-phase block NAS, variable hardware prediction, and differential hardware design are provided and described. A variable predictor is trained, as described herein. Then, a controller or policy may be used to iteratively modify a neural network architecture along dimensions formed by neural network architecture parameters. The modification is applied to blocks (e.g., subnetworks) within the neural network architecture. In each iteration, the remainder of the neural network architecture parameters are modified and learned with a differential NAS method. The training process is performed with two-phase block NAS and incorporates a variable hardware predictor to predict power, performance, and area (PPA) parameters. The hardware parameters may be learned as well using the variable hardware predictor.Type: ApplicationFiled: November 12, 2020Publication date: May 12, 2022Inventors: NIV ZEHNGUT, AMIR BEN-DROR, EVGENY ARTYOMOV, MICHAEL DINERSTEIN, ROY JEVNISEK

Patent number: 9106813Abstract: A noise elimination device includes a low pass filter unit, a noise filtering unit and a signal synthesis unit. The low pass filter unit generates a low frequency image signal by separating low frequency elements from an input image signal. The noise filtering unit generates a filtered image signal by suppressing noise in the low frequency image signal in horizontal and vertical directions. The signal synthesis unit generates an output image signal by combining the high frequency image signal and the filtered image signal.Type: GrantFiled: February 27, 2013Date of Patent: August 11, 2015Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Eugene Fainstain, Evgeny Artyomov

Patent number: 9002136Abstract: A denoising apparatus comprising an image input unit which receives pixel data including color information of pixels included in a correction target image, a denoising unit which denoises the pixel data by a weight based averaging method, wherein the weight is set to a maximum value when a difference value between a correction target block and a comparison target block in the correction target image is zero, decreases linearly to zero as the difference value increases until it reaches a threshold value, and is set to zero when the difference value is greater than or equal to the threshold value, and an image output unit which outputs the pixel data processed by the denoising unit. The denoising unit assigns a corrected weight value to at least a guaranteed number of comparison target blocks for an impulse block, where an impulse block is a correction target block for which the number of non-zero weight valued comparison target blocks is less than a predetermined guaranteed number.Type: GrantFiled: May 8, 2013Date of Patent: April 7, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Evgeny Artyomov, German Voronov, Jong-Hwa Lee
