title: Cross-validation and Training error of Lasso
body: <p>Just wanted to check. I have this plot of lasso on training dataset and cross-validation dataset. The red curve is training error while black is cross-validation error. </p>
  
  <p>This curve looks fine right? With increasing alpha, training error would increase while cross-validation error would go down. </p>
  
  <p>Is this understanding correct?</p>
