Quadratic Neural Network

Quadratic neural networks employ quadratic activation functions, enhancing their capacity to model complex non-linear relationships compared to traditional linear models. Current research focuses on understanding their theoretical properties, particularly concerning global optimality, generalization performance, and efficient training algorithms, often involving analyses of gradient descent dynamics and the development of novel architectures like QuadraNet. This research is significant because it offers potentially more efficient and expressive models for various machine learning tasks, including optimization problems and signal processing, while also providing insights into the fundamental dynamics of neural network training.
