I have a simple feedforward neural network with 2 input neurons (and 1 bias neuron), 4 hidden neurons (and 1 bias neuron), and one output neuron.
The feedforward mechanism seems to be working fine, but I have trouble fully understanding how to implement the backpropagation algorithm.
There are ...
I saw this question and thought it looked like a great opportunity to try my hand at the Strategy Pattern. I've never used it before, but I think I did pretty well. Did I?
The code below can also be found on github. I'm using C# 6.0 for this, so if there are any opportunities to use new feature...
Assume there is a list of unique strings. The implementation of that list is unknown. You need to check if a given string is unique after comparing with all elements in that list, and add it to that list.
What is the best way to tackle this problem using js?

My colleagues often ask me Dude could you remind me what I have to type to build this target?. So I eventually implemented a nice workaround in my Makefiles.
I wanted my Makefiles to have a help target that give some usage clues to the users. This is achieved with an embedded Perl script some m...

While writing a review of @MotokoKusanagi's Brainfuck interpreter, I decided to write my own implementation to illustrate a few points. In particular, I'd like it to be robust to malformed programs, and reasonably efficient (short of JITting the Brainfuck code).
Please point out any deficiencie...
I spend a needless amount of time indenting code by hand because just selecting code and pressing tab does not work. I know that there is ctrl+k but it only solves half of the problem since it only indents when the code is not indented enough (where "enough" is subjective since it will never inde...

I load a table in a div using .load() method.
If I look on the console I see the times taken to display the table:
4.98 seconds that firebugs says are spent "waiting" for a response (from a php backend)
9.94 seconds receiving data.
During the second event I see that the browser trhows an ale...

I call multiple Groovy scripts from Java, they both contain long-lived Groovy objects.
I would like my Groovy scripts to make some changes to a Java meta-class for a Java class (that have about 100 instances). However, the scripts should be able to make different changes, and chang...
I am trying to parse three numbers, like [2, 10, 2014] to a LocalDate using the new Java 8 Date and Time API.
All sounds relatively easy, right? Well, perhaps not.
The additional constraint is that I need to take into account the locale, as for example Dutch and American use different date forma...

I'm very new to SQL, but I'm coding a C# program that interacts with a database. There's a master database on my computer, and there's a client database on my tablet.

I've found that the function genfromtxt from numpy in python is very slow.
Therefore I decided to wrap a subroutine with f2py to read my data. The data is a matrix.
