Homework Statement
I am trying to train a neural network using the following training set:
(4,6)
(9,10)
(1,2)
(6,2)
So, if I enter input 4, it should give me 6. If I enter 9, output should be 10.
If I enter 3.5, it should approximate an output based on the training examples...

Hi there,
I was wondering if anyone out there was familiar with image classification algorithms. I have been creating histograms of pixel intensity distributions.
For example, suppose I have 100 images of a tiger and 100 images of a lion.
I create 100 histograms using...
My question is related to optical character recognition. So if I draw a T, how do I match it to T that accurately reflects the entire training data?
I.e. if I have pattern T1, pattern T2, .., are the sequences for n T's.
C1, C2,..,CN is C training points for n C's.
If I feed a single C...
I.e.
A new sequence is entered and we wish to identify group membership to T or C based on sample data for T and C. SInce T and C won't necessarily consist of 2 example database( 1 for each) but rather 1000 for T and 1000 C examples, how does one accurately calculate a match?
Homework Statement
If I have a 3*3 grid, or 3*3 matrix, which records clicked points.
I.e.
Pattern T =
[1,1] = 1
[1,2] = 1
[1,3] = 1
[2,1] = -1
[2,2] = 1
[2,3] = -1
[3,1] = -1
[3,2] = 1
[3,3] = -1
or
1 1 1
-1 1 -1
-1 1 -1

Homework Statement
Hi all,
I am trying to think of some intermediate (C,Java, Matlab) project ideas that would use the conjugate gradient, least squares regression (basiaclly a lot of statistical inference methods), lasso regression, and neural network feedback in order for a computer...
I think the placement of the eigenvectors is also not crucial due to the nature of the eigenvectors.
e^-1 and e act to still give the diagonal I believe. but i will try that some other time
Yep, I did try it all out and i got the diagonal
it took some time to get the inverse correct by hand but looking back at it
it's pretty straight forward.
Thanks for your help :)
Sorry I am trying to diagonalize the matrix h
I used MATLAB to check my results:
h =
2 1 0
1 2 1
0 0 2
>> [e,r] = eig(h)
e =
0.7071 -0.7071 -0.7071
0.7071 0.7071 0
0 0 0.7071r =
3 0 0...

ok, I thought I understood vector spaces but this problem is confusing the heck out of me.
A norm is a function that assigns a positive and finite length to...
