feedforward network not learning

[GoogleCodeExporter]

What steps will reproduce the problem?
1. training nff
2. large input --42 input neurons floaing point vales as inputs
3. out put (0,0,0,1)  ,(0,0,1,0),(0,1,0,0),(1,0,0,0)

What is the expected output? What do you see instead?
   decrease in error but constant error seen

What version of the product are you using? On what operating system?
   most recent version on my fedora 17(linux 3.7)

Please provide any additional information below.

This was to recognize handgesture where the inputs are x,y,z acceleration 
values and 4 patterns are the possible outputs

I seen only main(), and understand that you need scalable input and output 
parameters for range [-1, 1]. For example:

inp = inp / 10
tar = tar / 40
error=net.train(inp, tar, show=50, goal=0.0001)

Default output activation function may generate output range [-1, 1].
I also chenge goal of training for get better result

please do check the train function..
my input data are accelerometer data and target is 4 nodes with 3 zeros and
one 1 indicating the pattern

I need train samples for check it

1) You file in difficult format
2) Arrays have a different lenght (input 395, target 87). I cut input array
3) Output SSE error of train range in [15; 5]. My best result 1.0, I think it 
is norm (see train_result.png)

And? Train algorithm find local minimum, it is normally. Run script again

got it but am now facing another problem that is i can not load my net
using nl.net error is
File "./pro.py", line 45, in <module>
    main_()
  File "./pro.py", line 35, in main_
    gesture=simulate(data14);
  File "/home/sarath/gesture/my_part/ann.py", line 40, in simulate
    net=get_net()
  File "/home/sarath/gesture/my_part/t_sim.py", line 13, in main
    net=nl.load('net.net')
  File

line 54, in load
    with open(fname, 'r') as file:



IOError: [Errno 2] No such file or directory: 'net.net'

but when i run script in an another folder with same function its working
fine am here by uploading the code ,

the problem is in file ann.py function simulate0

>>>nl.load('net.net') 
set absolute path to 'net.net' file
