comment Finding peaks and oscillations in a signal
This is rather like the cross correlation idea - I was trying scaled versions of a Gaussian (chosen in a very heuristic manner!) but found it to be very sensitive to subtle signal changes. I'll give this approach a go and see how I get along with it, thanks!

comment How do I apply this PDE as an image filter?
@Kris I don't know anything about your problem personally, but Peter Kovasi has an anisotropic diffusion function on his page; perhaps his implementation may be of help to you? csse.uwa.edu.au/~pk/research/matlabfns

comment Mathematical introduction to machine learning
It's funny you say that because I was actually looking to go into fluids or pdes and due to circumstances I had to accept a phd closer to where I was living at the time! I didn't think it would be as interesting as I'm not a huge fan of stats, but some of the neural networks and Fourier analysis is actually very interesting. You'll fly through the material with your background :-)

Yes, that's right.

comment Mathematical introduction to machine learning
Many thanks :-) I'll have a read of Smola's text. I'm in a fairly similar position where I've gone from a maths degree to a PhD in pattern recognition and machine learning. I only did one basic stats course so would like a more mathematical text to supplement Ng's course and Bishop's book.

Or perhaps stats.stackexchange.com - I've read a few questions there regarding machine learning techniques. I'm currently learning from Ng's course and Bishop's book - so will be interesting to see if you find something nice!

comment Significance of orthonormal basis in wavelet analysis
@Tom perhaps you could suggest an example of what you suggest over bi-orthogonal?

Your WA input is different than the expression in the question.
