Simple Demo Issue

Nov 25, 2015 at 7:05 AM
Hi, I clone and build the CNTK by VS 2013 and test the simple demo. I find that the EvalErrPerSample is still large at the last epoch, such as:
Epoch[50 of 50]-Minibatch[ 381- 390 of 400]: SamplesSeen = 250; TrainLossPerSample = 0.69580664; EvalErr[0]PerSample = 0.50400000; TotalTime = 0.01640s; TotalTimePerSample = 0.06561ms; SamplesPerSecond = 15241
Epoch[50 of 50]-Minibatch[ 391- 400 of 400]: SamplesSeen = 250; TrainLossPerSample = 0.69382617; EvalErr[0]PerSample = 0.50000000; TotalTime = 0.01926s; TotalTimePerSample = 0.07704ms; SamplesPerSecond = 12980.

On the other hand, the prediction result is the same for all the testing samples.

How can I fix this issue, thanks.
