I'm interested in understanding human-level intelligence. Before we can figure out the theory of mind, I believe it's necessary to understand the patterns of signals that humans are dealing with. So at this moment, I'm working on finding the elementary mathematical structures of natural signals. There are not many of these structures and each of them is not necessarily complex. But when these simple elements entangle with each other, things quickly exceed the ability of our imagination. My job is to identify and then factorize them clearly, concisely and completely, or even uniformly. Thus we can build unsupervised and generative models for the signals, in a somewhat principled way. This might be the first step towards building a truly intelligent machine, which can dream as we do. To be honest, I might be looking for something that doesn't exist though I suspect there is a hidden gem in the mist, very close.
I like the Taoism in the Chinese culture and I think it's quite inspiring during my journey voyaging in signal spaces. My favorite philosophical point of view is that "为学日益，为道日损". This is my light in the darkness.
