  • Publication number: 20240004952
    Abstract: A bit-widths determination method selects bit-widths for mixed-precision neural network computing on a target hardware platform. An activation quantization sensitivity (AQS) value is calculated for each convolution layer in a neural network. The AQS value indicates the sensitivity of convolution output to quantized convolution input. One or more convolution layers are grouped into a quantization group, which is to be executed by a corresponding set of target hardware. A group AQS value is calculated for each quantization group based on the AQS values of the convolution layers in the quantization group. Then bit-widths supported by the target hardware platform are selected for the corresponding quantization groups. The bit-widths are selected to optimize, under a given constraint, a sensitivity metric that is calculated based on each quantization group's group AQS value.

  • Patent number: 9373755
    Abstract: A semiconductor device having light-emitting diodes (LEDs) formed on a concave textured substrate is provided. A substrate is patterned and etched to form recesses. A separation layer is formed along the bottom of the recesses. An LED structure is formed along the sidewalls and, optionally, along the surface of the substrate between adjacent recesses. In these embodiments, the surface area of the LED structure is increased as compared to a planar surface. In another embodiment, the LED structure is formed within the recesses such that the bottom contact layer is non-conformal to the topology of the recesses. In these embodiments, the recesses in a silicon substrate result in a cubic structure in the bottom contact layer, such as an n-GaN layer, which has a non-polar characteristic and exhibits higher external quantum efficiency.
