Web30. nov 2015 · 1. The textbook is comparing the random forest predicted values against the real values of the test data. This makes sense as a way to measure how well the model predicts: compare the prediction results to data that the model hasn't seen. You're comparing the random forest predictions to a specific column of the training data. WebAt the first level, each feature vector is CS-encrypted using a different random matrix for each forest. At query time, the user selects one matrix randomly from a set of R different matrices, and gets R encrypted results of which only one will be used.
