Abstract: In this brief, a novel approximation method and its optimized hardware implementation are proposed for the sigmoid function used in Deep Neural Networks (DNNs). Based on piecewise ...

Abstract: The sigmoid function is a representative activation function in shallow neural networks. Its hardware realization is challenging due to the complex exponential and reciprocal operations.

Cases of colorectal cancer in younger adults are climbing worldwide, driven by lifestyle changes and inherited genetic risks. Diet, obesity, and lack of early screening are playing a major role in ...

Genetics, the microbiome, and low screening rates may be factors in the increase, experts say. Here are risk factors for the disease—and the most common symptoms. This colorized abdominal X-ray shows ...
