US Patent:
20200372363, Nov 26, 2020
Filed:
Jan 19, 2020
Appl. No.:
16/746941
Inventors:
- Taipei City, TW
Bike Xie - San Diego CA, US
YIYU ZHU - Nantong City, CN
International Classification:
G06N 3/08
G06N 3/063
G06N 5/04
G06N 20/00
Abstract:
A computing network includes a plurality of processing nodes. A method of training the computing network includes a processing node in the plurality of processing nodes computing an output estimate according to a weight defined by a weight variable and a connectivity mask, and adjusting connectivity variables according to an objective function to reduce a total number of connections between the plurality of processing nodes and reduce a performance loss indicative of how different the output estimate is from a target value. The connectivity mask represents a connection between the processing node and a preceding processing node in the plurality of processing nodes and is derived from a connectivity variable.

Low Precision And Coarse-To-Fine Dynamic Fixed-Point Quantization Design In Convolution Neural Network

View page
US Patent:
20200193270, Jun 18, 2020
Filed:
Aug 27, 2019
Appl. No.:
16/551753
Inventors:
- Taipei City, TW
YUNHAN MA - San Diego CA, US
Bike Xie - San Diego CA, US
Hsiang-Tsun Li - Taichung City, TW
JUNJIE SU - San Diego CA, US
Chun-Chen Liu - San Diego CA, US
International Classification:
G06N 3/04
G06N 3/08
Abstract:
After inputting input data to a floating pre-trained convolution neural network to generate floating feature maps for each layer of the floating pre-trained CNN model, a statistical analysis on the floating feature maps is performed to generate a dynamic quantization range for each layer of the floating pre-trained CNN model. Based on the obtained quantization range for each layer, the proposed quantization methodologies quantize the floating pre-trained CNN model to generate the scalar factor of each layer and the fractional bit-width of a quantized CNN model. It enables the inference engine performs low-precision fixed-point arithmetic operations to generate a fixed-point inferred CNN model.

16/551743
Inventors:
- Taipei City, TW
Bike Xie - San Diego CA, US
Hsiang-Tsun Li - Taichung City, TW
Junjie Su - San Diego CA, US
Chun-Chen Liu - San Diego CA, US
International Classification:
G06N 3/08
G06N 3/063
G06F 7/544
Abstract:
A system for operating a floating-to-fixed arithmetic framework includes a floating-to-fix arithmetic framework on an arithmetic operating hardware such as a central processing unit (CPU) for computing a floating pre-trained convolution neural network (CNN) model to a dynamic fixed-point CNN model. The dynamic fixed-point CNN model is capable of implementing a high performance convolution neural network (CNN) on a resource limited embedded system such as mobile phone or video cameras.
