On Neural Differential EquationsPatrick KidgerMathematical InstituteUniversity of OxfordA thesis submitted for the degree ofDoctor of PhilosophyTrinity 2021 [ ] 4 Feb 2022 AbstractThe conjoining of dynamical systems and deep learning has become atopic of great interest. In particular, Neural differential Equations (NDEs)demonstrate that Neural networks and differential equation are two sidesof the same coin. Traditional parameterised differential Equations are aspecial case. Many popular Neural network architectures, such as residualnetworks and recurrent networks, are are suitable for tackling generative problems, dynamical systems,and time series (particularly in physics, finance, .. ) and are thus ofinterest to both modern machine learning and traditional mathematicalmodelling. NDEs offer high-capacity function approximation, strong pri-ors on model space, the ability to handle irregular data, memory efficiency,and a wealth of available theory on both doctoral thesis provides an in-depth survey of the include: neuralordinarydifferential Equations ( for hybridneural/mechanistic modelling of physical systems); neuralcontrolleddif-ferential Equations ( for learning functions of irregular time seri)
demonstrate that neural networks and di erential equation are two sides of the same coin. Traditional parameterised di erential equations are a special case. Many popular neural network architectures, such as residual networks and recurrent networks, are discretisations. NDEs are suitable for tackling generative problems, dynamical systems,
