I am really confused as to how this works? You have a critique but where does the critique come in? Also is their a difference between activation on hidden nodes and output nodes? Does the critique come in during the hidden node? or the input node?
Thanks

i am only filling in the top half of my my weight matrix.... so if the sum is greater than 0 I change the neuron to the oppossite otherwise i leave it the same?

Added mouse listener it works whenever I click anywhere not only when I click on the circles

i have 2 panels because i have two windows...
The draw cell method creates a graphic object and i want to change color depending on if the graphic object is selected or not. I can't even create a handle to it.

TITLE SHOULD ACTUALLY BE: how to get mouselistener to work on method in an class in java

If I click a circle it should change the color of the circle. But, I am having difficult getting it to work.
Help appreciated.

Main just calls this class and calls the init function.

thanks I got it to work.

Trying to implement the learning algorithm but running into problems. How do I skip the value stored since I do not want to do calculations with it?

void Learn(int* weightmatrix, int* pattern, int numOfPatterns, int numOfNeurons){

	int skip[5]; //true means skip
	for(int patternNum = 1; patternNum <= numOfPatterns; patternNum++)
	{
		for(int neuronNum = 1; neuronNum <= numOfNeurons ; neuronNum++)
		{
			skip[5] = {false, false, false, false, false}; //reset
			skip[neuronNum-1] = true; 
			int sum = 0;
			for(int numOfConnectionsToANeuron = 1; numOfConnectionsToANeuron< (numOfNeurons - 1); numOfConnectionsToANeuron++)
			{
				for(int skipCounter = 0; skipCounter < numOfNeurons; skipCounter++)
				{
					if(skip[skipCounter] == false)
					{
						sum = (pattern[(neuronNum-1)* patternNum]* weight[]) + sum;
					}
					else if(skip[skipCounter] == true)
					{

					}
				}
			}
		}
	}
}

I am trying to implement a hopfield net to learn patterns.

This is what I current have....

I am current having it create a random number of patterns based on the number of neurons

Next I am trying to make a weight matrix

Should I have a seperate weight matrix for every or is one good enough to apply the hebbs learning rule to? One should be enough since I know based on nodes how many it can recognize based on following formula: N/4 * log N, where N is numofNodes. it is log base 2?

Thanks.

#include <math.h>

	cout<<"Number of Patterns being stored is "<<numOfPatterns<<endl;
    pattern = new int[numOfPatterns * numOfNeurons];
	randomlyCreatePatterns(numOfNeurons, numOfPatterns, pattern);

the only problem we have is that the ctrl-c doesn't work.

This is due by tonight.... So, don't have enough time to start with threading. We seem to have the sleep on the third job queue working. The only problem is the ctrl-c. Ctrl-c is also the terminator for a process in UNIX. I think that may be the problem.

please help. any suggestions.

Any suggestions?

Here is the assignment:

Process Scheduling Project on

Write a C/C++ Process Scheduler program on UNIX to simulate the round robin priority scheduler with four queues: TASK_QUEUE, SERVER_QUEUE, POWER_USER_QUEUE, and USER_QUEUE.
The program should create the following processes (or threads) for the scheduler simulation:

1. The job-generation process (or thread) will randomly generate new jobs and put them into the job queues. The new jobs can be simple print and sleep/usleep operations.
The job queues may be stored in an external file so that it can be accessed by other process if processes are used (or store in an array of list if threads are used).

2. The scheduler process (or thread) will select a job from the job queues and create a new work process (or thread) to run the job. The scheduler will use the following scheduling algorithm:

a. Jobs in the TASK_QUEUE have the highest priority. These jobs will be run until finished.

b. Jobs in the SERVER_QUEUE have the second priority. These jobs will be run using the round robin algorithm.
(You should attach a random number from 1 to 3 with the job to indicate the number of quantum times that the job needed to be run to finish.)

c. Jobs in the POWER_USER_QUEUE have the third priority. These jobs will be run and then blocked for the input. It will become ready to run again when user types the interrupt key …

Having problems with executing jobs using fork. The code is supposed to create one job and execute one job and repeat this multiple times. We are only supposed to use usleep in the jobgeneration() function.

We are having trouble sleeping and executing ctrl-c in the execute job function.

thanks but I got it to work I created a class and created static members so that I can use the back, next and cancel buttons.

Any suggestions. I am assuming I use a registery but i dont' know which member to use.
Thanks.

Take line below which is in batch file and convert it in C# so that I don't have to create a seperate file. Thanks! Any suggestions? I have spent way too long on this.

I still get the same exception. I think its because I am trying to access it in multiple forms. Maybe???
Btw I have each form set up as static so that I can add back button to it.

Heres the exception:
at Microsoft.VisualStudio.Debugger.Runtime.Main.ThrowCrossThreadMessageException(String formatString) at System.Windows.Forms.SafeNativeMethods.GetWindowTextLength(HandleRef hWnd) at System.Windows.Forms.Control.get_WindowText() at System.Windows.Forms.TextBoxBase.get_WindowText() at System.Windows.Forms.Control.get_Text() at System.Windows.Forms.TextBox.get_Text()

Please help.

that doesn't work, it just adds the @ sign in front of the string and still keeps 2 \\

I have set the textbox to public so that another form can access it but when i run it in debug mode with the following line it gives me exception so it doesn't store correct directory.
For example:
If I enter D:\newfolder it gives me D:\\newfolder. Why does it add the extra \.

Here's the exception:
An exception 'Microsoft.VisualStudio.Debugger.Runtime.CrossThreadMessagingException' occurred

Here's the line where the exception occurs.

Choose is a class in the same namespace as the method which contains this string.
The method is in a different class than the choose class.
txtbxTargetDir is the name of the textbox.

string targetPath = StaticFormInstances.choose.txtbxTargetDir.Text;

I was wondering how you do this. Would you have to use delegates and event handlers or can you do it through application.Run(object) and call that in the clickevent but I need to keep a reference to previous form. but that doesn't seem possible.

In the following code how to fix problem that the batch file won't get created. When I run in debug mode exception I get is "could not find part of path"

I have added a reference to dll file in VS 2008. Yet I still get an error. Not sure why, do I have to do some other changes to get it to work?

Here's the assignment:
You are to create a single server (in either Java or C/C++) which can service both C/C++ and Java clients.

The protocol of the server is as follows:

1.  The client contacts the server.
2.  The client performs a single send of a data packet containing the following items (in the order specified):
a.  a 32-bit signed integer (int)
b.  a 64-bit floating point value (double)
c.  another 64-bit floating point value (double)
d.  another 32-bit signed integer (int)
e.  an array of 80 bytes representing a C char array 
(i.e. a C “string” – NOT a Java String or a C++ string, just
a character array with a null character (character 0) value to mark the end of the string)
3.  The server responds with a single data packet (a single send) containing:
a.  a 64-bit floating point value (double) 
the value of which should be a * cos(b) + sin(c) * d, where
a,b,c, and d are the values sent in the client packet above
b.  an array of 80 bytes representing a C char array
           the value of which should be the bytewise reversal of e in the
           client message.
           For example, if the client sends:
            “Hello World!”  (where ) represents the null character,
           the server should reply with:
            “!dlroW olleH”
           Note that the remainder of the byte array (after the first zero 
            byte) is to be ignored in both the client and the server messages.  (However, both must send a complete …

how would you do that?

Language similar to LISP

I don't think you can use cons twice.

maybe
(define a '('()))

so the problem was with the initialization of the arrays.

its doesn't like me doing matching for some reason when it is declared as a string at the end where I of the blackandwhite method.

problem is with evaluate black and white method.

When i try it goes heywire and gives me 35 errors. all for the erase command. :(

for(int i=0; i<populationsize_; i++)
	{

So I tried your way....
It works for 90% of them

It doesn't work for some of them. answer i enter
is=1232 it gives.... W|B|Total

2131 1 |1|2

the temp version of array is replaced by bool one in my code. So the temp version of answer will store which ever ones don't contain black?? Anyways I am off to sleep. Have a week to finish up this code.

that's exactly what i am doing here...

if(population_[k][j]==answer_[i])

you need the && condition so that you don't double count.

The second array is necessary to say that already accounted in black so don't account it again.... since you don't want the total of black and white to be greater than 4.

in regards to the second comment, i don't care about positions, i care about number of white and blacks.

WaltP your way doesn't even work... you need the 2nd array to say where you already guessed that position or not.
