Hopfield Network

Multilayer Perceptron

Neural network homework 2 assigned during 10/22~11/05:
Coding during 11/03~11/06
Delayed again...XD



Functional list:
1.insert/modify/delete the hidden layers of MLP
2.show weight values of each connected edges between nodes dynamically
3.sample data normalization
4.the structure of MLP view(move,magnify and shrink)

Hyper-sphere Decision Boundaries

The homework is done for finding a decision boundary with the simplest way between two-class samples.

That is, to find the domain with a center(u) and a radius(r) approaching the decision boundary.











My way to approach the boundary is:
1. Find the centers and the max domains of two training samples individually.
2. Choose the smallest class domain and define the decision boundary.
3. Then the work is done.

The Perceptron

This is my neural network homework 1 assigned during 10/1~10/15.
The software is developed with WxWidgets and OpenGL.
For surfing, I estimate the lefting days that I cought finish the homework.(from 10/13)
However, I can't! So the job is delayed.







Perceptron: the simplest classifier in computer science.
There are many different kinds of data.
Maybe in the 2-dimenstions space, 3-dimenstions space and so on.
So the job is done for classifying the data.

I find WxWidgets have a full supported with OpenGL.
My prexy told me another 3D library - VTK.
It's time for researching, maybe...
