comment How to help MMA to simplify integrands?
Integration is, as you will be quite aware of, not a straightforward process. There is not a single path that is guaranteed to lead to the solution and many different tricks may have to be used before a solution is reached. I note that the indefinite integral in this case is found almost instantaneously and I assume that Mathematica spends most time in determining appropriate conditions for the constants. And then, a few hundred integrals taking the timing I got should not be really a problem. Looks like they would have been calculated in the time you spent here on this question ;-)

comment How to help MMA to simplify integrands?
The integral took 14 seconds on my laptop (V10). Is that really a problem?

comment Eliminate symbols from Lists
The key is to use ToRules to transform the output of Reduce to rules and then use ReplaceAll (/.) to transform the rules into numbers. tip: do look at the bottom of the help page of functions you're working with. ToRules, for instance, is listed at the bottom of the Reduce help page.

comment How to make Import recognize a new file extension?
Glad it works for you. It's unfortunately not pretty, but probably the best for now. It would be nice if adding to the extension mapping system file would work, but it never did for me. BTW @pinging only works if I already contributed to the comments on this page.

comment How to change NeuralNetwork options?
So, it is indeed, as I assumed, a specific "HiddenLayers" format that is needed, but I only tried to specify functions instead of names as strings :-(
