Rational Neural Networks Offer Expressivity Advantages Over Standard Activations

Researchers have introduced Rational Neural Networks (RNNs), which utilize trainable low-degree rational activation functions. These networks demonstrate superior expressivity and parameter efficiency compared to traditional piecewise-linear and smooth activations like ReLU and Tanh. Theoretical analysis shows an exponential gap in approximation capabilities, with RNNs requiring significantly fewer parameters for a given error target. In practical applications, RNNs integrate seamlessly into existing architectures and training pipelines, often matching or exceeding the performance of standard activations. AI
