 Analysing and quantifying the approximation properties of neural networks is of paramount importance for the design of efficient architectures. In this course, we will first present approximation error estimates for neural networks and will discuss their relation to the underlying architectures. This will be done in the context of differential equations and inverse problems, which will provide our test cases. We then will connect these insights to the training of neural networks. Here, we will present multi-scale and decomposition methods for training, which allow for the efficient and parallel training of neural networks. 


Obtain knowledge on: mathematical description of neural networks; central concepts and ideas of approximation theory for neural networks; fundamental properties of different first and second order optimization techniques for training neural networks; parallel methods and multiscale methods for training neural networks; solving differential equations with neural networks (PINNs)
