Is quantum mechanical tunneling statistically independent?

Let us consider two boxes of different energies that are separated by a barrier and box 1 is filled with many electrons. The barrier allows the electrons to tunnel from box 1 to the other side...

Can the minimum Mean Squared Error of a neural network be predicted using the Canonical Correlation of the input and target matrices?

Let us assume we have a d1-by-d matrix (lets us call this one A) for the input and a d2-by-d (B) matrix for the target of a neural network. I see that the canonical correlation between the...

Can one use blind image restoration algorithms to observe molecules using a light source which has a longer wavelength then the molecule itself?

It seems to me that as the wavelength of the light gets longer than the object one is trying to view, the image should start blurring out, however i'm not sure if quantum mechanics makes this...
