We therefore develop a new infinite width limit, the representation learning limit, that exhibits representation learning mirroring that in finite-width networks, yet at the same time, remains extremely ... Finally, we use this limit and objective to develop a flexible, deep generalisation of kernel methods, that we call deep kernel machines (DKMs). ... This contrasts with a deep linear neural network, which has infinitely many optimal settings for the weights. Note that for the objective to be well-defined, we need K(G) to be full-rank. ...

The training dynamics and generalization properties of neural networks (NN) can be precisely characterized in function space via the neural tangent kernel (NTK). ... In nonlinear networks with multiple outputs, we identify the phenomenon of kernel specialization, where the kernel function for each output head preferentially aligns to its own target function. ... Both evaluation of the infinite width kernels and training were performed with the Neural Tangents API (Novak et al., 2020) . E.1. ...

This property enables the reformulation of the signal recovery as a low-rank structured matrix completion, which comes with performance guarantees. ... This framework is centered on the fundamental duality between the compactness (e.g., sparsity) of the continuous signal and the rank of a structured matrix, whose entries are functions of the signal. ...

Under this model, we show that each layer of the infinite-width neural network can be characterised by two simple quantities: a non-negative scalar parameter and a L\'evy measure on the positive reals. ... This article studies the infinite-width limit of deep feedforward neural networks whose weights are dependent, and modelled via a mixture of Gaussian distributions. ... These neural network models therefore are asymptotically equivalent to a model with iid Gaussian weights in the infinite-width limit. ...
