Artificial Intelligence and Machine learning have been widely used in various fields of mathematical computing, physical modeling, computational science, communication science, and stochastic analysis. Approaches based on Deep Artificial Neural Networks are very popular in our days. Depending on the learning task, the exact form of Deep Artificial Neural Networks is determined via their multi-layer architecture, activation functions and the so-called loss function. However, for a majority of deep learning approaches based on Deep Artificial Neural Networks, the kernel structure of neural signal processing remains the same, where the node response is encoded as a linear superposition of neurons, while the non-linearity is triggered by the activation functions. In the current Matlab Toolbox analyses the neural signal processing in Deep Artificial Neural Networks from the point of view of homogeneous chaos theory as known from polynomial chaos expansion introduced by Norbert Wiener in 1938. It employs the data-driven generalization of polynomial chaos expansion theory known as arbitrary polynomial chaos (aPC: Oladyshkin S. and Nowak W., 2012 and 2018) to construct a corresponding multi-layer representation of a Deep Artificial Neural Network. Doing so, we generalize the conventional structure of DANNs to Deep arbitrary polynomial chaos neural networks (DaPC NN: Oladyshkin et al. 2023).
