looking at the previous graphwe immediately see that adding more training data will not helpas the dashed line corresponding to the test error seems to stay above the only option we have is to decrease the complexity either by increasing or by reducing the feature space reducing the feature space does not help here we can easily confirm this by plotting the graph for simplified feature space of linkcount and numtexttokens refer to the following graphwe will get similar graphs for other smaller feature sets as well no matter what subset of features we takethe graph will look similar at least reducing the model complexity by increasing shows some positive impact this is illustrated in the following tablek mean(scoresstddev(scores
