Title:        Why and Why Not Convolutional Neural Networks (CNNs)?

Abstract: The superior performance of Convolutional Neural Networks (CNNs)
has been demonstrated in many applications such as image classification,
detection and processing. Yet, the CNN solution has its own weaknesses such
as robustness against perturbation, scalability against the class number
and portability among different datasets. Furthermore, CNN’s working
principle remains mysterious. In this talk, I will first explain the
reasons behind the superior performance of CNNs. Then, I will present an
alternative solution, which is motivated by CNNs yet allows rigorous and
transparent mathematical treatment, based on a data-driven Saak (Subspace
approximation with augmented kernels) transform. The kernels of the Saak
transform are derived from the second-order statistics of inputs in a
one-pass feedforward way. Neither data labels nor backpropagation is needed
in kernel determination. The pros and cons of CNNs and multi-stage Saak
transforms are compared.
