title: Test accuracy vs Training time on Weka
body: <p>From what I know, test accuracy should increase when training time increase(up to some point); but experimenting with weka yielded the opposite. I am wondering if misunderstood someting.
  I used diabetes.arff for classification with 70% for training and 30% for testing. I used MultilayerPerceptron classifier and tried training times 100,500,1000,3000,5000.
  Here are my results,  </p>
  
  <pre><code>   Training time   Accuracy  
     100             75.2174 %
     500             75.2174 %
     1000            74.7826 %
     3000            72.6087 %
     5000            70.4348 %
     10000           68.6957 % 
  </code></pre>
  
  <p>What can be the reason for this? Thank you!</p>
