The `=` sign in `Definition[f]` doesn't mean much: it's just cosmetic. You should look at the `DownValues` of `f`. As you can see, all `DownValues` are delayed rules: In[13]:= DownValues[f] Out[13]= {HoldPattern[f[-1, 0, 0]] :> 81, ...
Training on a dataset like that is going to require some thinking, but you should start by reading the tutorial about this subject in the documentation: http://reference.wolfram.com/language/tutorial/NeuralNetworksLargeDatasets.html Basically,...
If you plot the data on a log scale, you'll notice that you don't get a straight line: ListLogPlot[data] ![enter image description here][1] This is a clear indication that a simple decaying exponential is not going to give a good fit to...
I recently finished a major overhaul of my Bayesian inference package on Github: https://github.com/ssmit1986/BayesianInference and wanted to give a small overview of what it can do. If you're interested, the repository has a notebook with...
Good suggestion about `Tuples`. I added a `lazyTuples` function on my development branch, though it's probably not in its final form yet. I based the methodology of off the SE answer below. It's well worth a read if you ever want to work with...
Ok, here's one attempt. This function looks for patterns (with specified minimum an maximum length) repeated a minimum/maximum number of times: findRepeatedPatterns[ string_String, minMaxSequenceLength_List, ...
I don't think `NDSolve` has capabilities to use variable boundary limits like that. The only method to try I can think off right now, is to re-scale the time axis to fit this equation. So in your ODEs you introduce `tnew = t/tf` so that `0
Hi S G. I appreciate your problem, but unfortunately I don't have that much time to spare and your code is simply quite difficult to read. The only way I could really assess the problem is by taking it apart completely and rewriting it, which is a...
In my opinion, if you want to test if two quantities are related by a power law, the best way is to do a log-log plot since this will immediately show you a straight line if you're right. Humans are very good at recognizing straight lines by eye....
Ok, I didn't expect that to work. I tried some other distributions myself and didn't find any other ones that worked even when while attempting some really elementary ones (like a 2D normal distribution). It's good to know polynomials work, but the...
