Script environment training

[flatmax@cse.unsw.edu.au (Matthew Flax)]

Hello PDP++ peops,
     
I am training a neural network using a script environment.
     
I find that after the first step in training, reasonable weights go to
infinity !
   
My BpConSpec_0 has the following properties :
lrate=0.05
momentum = 0.9
momentum type = before lrate
decay =0

My script is like so :

double fileNum, loc;
fileNum=drand48(); loc=drand48();
cout<<"FileNum = "<<fileNum<<" loc = "<<loc<<endl;
String fname;
fname="./generatePhase";
system(fname + " " + fileNum + " " + loc);
int i;
{ float_RArray* ths =
.projects[0].environments[0].events[0].patterns[0]->value;
fstream input;
input.open("freq.dat", ios::in);
for (i=0;i<256;i++)
        input>>ths[i];
input.close();
}
{ float_RArray* ths =
.projects[0].environments[0].events[0].patterns[1]->value;
fstream input;
input.open("phase.dat", ios::in);
for (i=0;i<256;i++)   
        input>>ths[i];
input.close();
}


Any ideas ?
