<span class="gmail-HALYaf gmail-XQINac gmail-R21Rlc gmail-KKjvXb" id="gmail-tabEventDetails"><b>Title</b>: Foundations of deep convolutional models through kernel methods<br><br><b>Abstract:</b>
Deep learning has been most widely successful in tasks where the data
presents a rich structure, such as images, audio, or text. The choice of
network architecture is believed to play a key role in exploiting this
structure, for instance through convolutions and pooling on natural
signals, yet a precise study of these properties and how they affect
learning guarantees is still missing. Another challenge for the
theoretical understanding of deep learning models is that they are often
over-parameterized and known to be powerful function approximators,
while being seemingly easy to optimize using gradient methods.<br>We
study deep models through the lens of kernel methods, which naturally
define functional spaces for learning in a non-parametric manner, and
have links to optimization of infinitely-wide deep networks in certain
regimes.<br>This allows us to study invariance and stability properties
of various convolutional architectures by studying the geometry of the
kernel mapping, as well as approximation properties of learning in
different regimes. Additionally, our kernel point of view defines a
natural complexity measure, the RKHS norm, which we leverage empirically
to regularize deep networks for improved generalization on small
datasets, and for better robustness to adversarial examples.</span>
