Constructive Approximation by Superposition of Sigmoidal Functions
Analysis in Theory and Applications, 2013 In this paper, a constructive theory is developed for approximating func- tions of one or more variables by superposition of sigmoidal functions. This is done in the uniform norm as well as in the L p norm. Results for the simultaneous approx- imation, with the same order of accuracy, of a function and its derivatives (whenever these exist), are ...

Enzyme-Based Logic: OR Gate with Double-Sigmoid Filter Response
, 2012 The first realization of a biomolecular OR gate function with double-sigmoid response (sigmoid in both inputs) is reported. Two chemical inputs activate the enzymatic gate processes resulting in the output signal: chromogen oxidation, which occurs when ...

Two-Dimensional Convolutional Recurrent Neural Networks for Speech Activity Detection [PDF]
, 2019 Speech Activity Detection (SAD) plays an important role in mobile communications and automatic speech recognition (ASR). Developing efficient SAD systems for real-world applications is a challenging task due to the presence of noise.
