Backpropagation Program Tv
I have coded up a backpropagation algorithm in Matlab based on these notes: My network takes input/feature vectors of length 43, has 20 nodes in the hidden layer (arbitrary parameter choice I can change), and has a single output node. I want to train my network to take the 43 features and output a single value between 0 and 100. The input data was normalized to zero mean and unit standard deviation (via z = x - mean / std) and then I appended a '1' term to input vectors to represent a bias. My targetValues are just single numbers between 0 and 100.
A simple example of backpropagation algorithm. Learn small neural network basic functions like predefined examples: AND, XOR or 2D distance. Import and export of custom tasks from and to xml or well readable csv. Integration with www browser. Creating new or editing loaded tasks in an editor is also possible. You can show the network anatomy and all weights and also the result with marked training set or exact output for set input. If learning failes, restart whole learning algorithm or just single neuron weights.

Alpha learning speed is automatic and configurable. Help on each screen. This program may be useful for students of a basic course of artificial neural networks.
It illustrates well that learning of neural networks is a complex task and basic backpropagation without any improvements can only solve very simple tasks. Words cannot describe how amazing this app is. Makes my inner geek go berserk. Really helps you gain an intuitive feel for how artificial neural networks are structured logically, and has great samples for those who quickly want to test proof of concepts. The xml and csv import / export tool is also actually really useful.
The author has also written a pretty comprehensive manual to help users learn all the concepts used in the app, which has greatly assisted my learning. Many thanks to the author for this great app. Words cannot describe how amazing this app is. Makes my inner geek go berserk.
