Here's my Salk web-page from way back.
Here's me giving a 30 minute talk Levels, Time and Models about Levels in Biology.
Here's me giving a 85 minute talk Emergence and Submergence in the Nervous System.
(The production on the latter is not so good, so here are the slides.
Also, if you wait a few minutes in, the audio drastically improves.)
What am I doing? If you watch either of these you will see, at least, where I am starting from.
I really want to crack this, and I think it can be done before too long.
Also, I believe we must solve these problems.
There are 3 steps to uniting physics, biology and machine learning:
(1) Solve the time series density estimation problem
(2) Solve the sensory-motor density estimation problem
(3) Solve the levels density estimation problem
The clues to (2) and (3) lie in (1).
I am working on (1) and I think I've got it.
The reinforcement learning literature, while elegant, has nothing relevant to say about these deep problems.
And unfortunately there's no way around it: to really crack this we are going to have to "get real".
We will have to absorb and augment the emerging non-equilibrium statistical mechanics and (cough) quantum theory.
I know this is a radical view, but still, I believe it to be correct.
Fortunately, both these branches of physics, in their core mathematical structure, are relatively simple.
Here's an unsatisfactory paper Towards a cross-level theory of neural learning that explains what I was thinking up till about 2008.
Here is my CV. (Ignore the stuff about the cyclist journalist - that's not me :)
