My maths is not very strong so please bare with. I have a set of data sets which contains 'n' amount of Gaussians. After a little googling I found that, the derivatives of my data could help me determine the amount of gaussians in my data.

I found this link particularly helpful. In the link they calculate the 1st and 2nd derivative, but what do these mean? and how should they be interpreted? Lastly, how are the derivatives calculated?

So, what you mean to say is that you have a linear combination of Gaussians? – Raskolnikov May 28 '12 at 16:01
