( #3333=superdoc: print w/replies, xml ) Need Help??

I have taken your recommendations into consideration. Yet now I am having problem with handling the output of the test set of examples on the network. It appears that the network returns an array of values, but all the values are the same.

use strict; use AI::NNFlex::Backprop; use AI::NNFlex::Dataset; use Data::Dumper; my $n = 0.4; my $num_epochs = 100; my $network = AI::NNFlex::Backprop->new(learningrate=>.9, bias=>1, ); $network->add_layer(nodes=>3,activationfunction=>'tanh'); #$network->add_layer(nodes=>3,activationfunction=>'tanh'); #$network->add_layer(nodes=>2,activationfunction=>'tanh'); #$network->add_layer(nodes=>3,activationfunction=>'tanh'); $network->add_layer(nodes=>5,activationfunction=>'tanh'); $network->add_layer(nodes=>2,activationfunction=>'sigmoid'); $network->init(); my $test_set = AI::NNFlex::Dataset->new([ [6.28318,1.570795,0], [1,0], [6.28318,1.570795,1.570795], [0,-1], [6.28318,1.570795,3.14159], [-1,0], [6.28318,1.570795,4.712385], [0,1], [6.28318,1.570795,6.28318], [1,0], [6.28318,1.570795,7.853975], [0,-1], [6.28318,3.14159,0], [0,-1], [6.28318,3.14159,1.570795], [-1,0], [6.28318,3.14159,3.14159], [0,1], [6.28318,3.14159,4.712385], [1,0], [6.28318,3.14159,6.28318], [0,-1], [6.28318,3.14159,7.853975], [-1,0], [6.28318,4.712385,0], [-1,0], [6.28318,4.712385,1.570795], [0,1], [6.28318,4.712385,3.14159], [1,0], [6.28318,4.712385,4.712385], [0,-1], [6.28318,4.712385,6.28318], [-1,0], [6.28318,4.712385,7.853975], [0,1], [6.28318,6.28318,0], [0,1], [6.28318,6.28318,1.570795], [1,0], [6.28318,6.28318,3.14159], [0,-1], [6.28318,6.28318,4.712385], [-1,0], [6.28318,6.28318,6.28318], [0,1], [6.28318,6.28318,7.853975], [1,0], [6.28318,7.853975,0], [1,0], [6.28318,7.853975,1.570795], [0,-1], [6.28318,7.853975,3.14159], [-1,0], [6.28318,7.853975,4.712385], [0,1], [6.28318,7.853975,6.28318], [1,0], [6.28318,7.853975,7.853975], [0,-1], [7.853975,0,0], [1,0], [7.853975,0,1.570795], [0,-1], [7.853975,0,3.14159], [-1,0], [7.853975,0,4.712385], [0,1], [7.853975,0,6.28318], [1,0], [7.853975,0,7.853975], [0,-1], [7.853975,1.570795,0], [0,-1], [7.853975,1.570795,1.570795], [-1,0], [7.853975,1.570795,3.14159], [0,1], [7.853975,1.570795,4.712385], [1,0], [7.853975,1.570795,6.28318], [0,-1], [7.853975,1.570795,7.853975], [-1,0], [7.853975,3.14159,0], [-1,0], [7.853975,3.14159,1.570795], [0,1], [7.853975,3.14159,3.14159], [1,0], [7.853975,3.14159,4.712385], [0,-1], [7.853975,3.14159,6.28318], [-1,0], [7.853975,3.14159,7.853975], [0,1], [7.853975,4.712385,0], [0,1], [7.853975,4.712385,1.570795], [1,0], [7.853975,4.712385,3.14159], [0,-1], [7.853975,4.712385,4.712385], [-1,0], [7.853975,4.712385,6.28318], [0,1], [7.853975,4.712385,7.853975], [1,0], [7.853975,6.28318,0], [1,0], [7.853975,6.28318,1.570795], [0,-1], [7.853975,6.28318,3.14159], [-1,0], [7.853975,6.28318,4.712385], [0,1], [7.853975,6.28318,6.28318], [1,0], [7.853975,6.28318,7.853975], [0,-1], [7.853975,7.853975,0], [0,-1], [7.853975,7.853975,1.570795], [-1,0], [7.853975,7.853975,3.14159], [0,1], [7.853975,7.853975,4.712385], [1,0], [7.853975,7.853975,6.28318], [0,-1], [7.853975,7.853975,7.853975], [-1,0] ]);

my $epoch = 1; my $err = 1; while($err > .001 && $epoch < 100) { $err = $train_set->learn($network); my $outputsRef = $test_set->run($network); print Dumper($outputsRef); print "Error: $err\n"; $epoch++; }

The output of the network with the test set gives the following.

$ perl test1.pl $VAR1 = [ [ '2.22776546277668e-07', '0.011408329955622' ], [ '2.22776546277668e-07', '0.011408329955622' ], [ '2.22776546277668e-07', '0.011408329955622' ], [ '2.22776546277668e-07', '0.011408329955622' ], [ '2.22776546277668e-07', '0.011408329955622' ], [ '2.22776546277668e-07', '0.011408329955622' ], .... ....

Am I handling the output of the network in correctly? The module says that Runs the dataset through the network and returns a reference to an array of output patterns. I guess I am not handling the reference array correctly.

Thanks for all the help.
