There are 3 steps to uniting physics, biology and machine learning:
There are new results on time series analysis coming :)

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.

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 the only paper I have written on the Levels issue. It covers my thinking up till about 2008:
Towards a cross-level theory of neural learning

There are new results on time series analysis coming :)
