Improving random forest accuracy

Hello,

I have applied random forest, its accuracy is 99 percent while training and cross validation but it reduces to 80 percent with test set. Please tell me how to improve accuracy with test set.

Re: Improving random forest accuracy

IReducing the classification model's fit to the training data (i.e., building a simpler model that fits this data less closely) *may* help. Also, if you have *prior* knowledge implying that a predictor attribute behaves differently in the test data than in the rest of the data, it might be better to remove it from the data.

Cheers,

Eibe
