The activation function has a critical influence on whether a convolutional neural network in deep learning can converge or not; a proper activation function not only makes the convolutional neural ...

We derive a tight, single-term, purely exponential, lower bound on the Gaussian Q-function, along with a method to optimize its tightness and a fast iterative method for its inversion. To illustrate ...

Flexible energy devices are essential for future small and flexible devices, and there are many challenges to create deformable energy devices. In this study, we developed a lightweight and flexible ...
