WebbWe define a new random forest proximity measure called Random Forest-Geometry- and Accuracy-Preserving proximities (RF-GAP) that defines a data geometry such that the proximity-weighted predictions exactly match those of the random forest for both regression and classification problems. Under our definition, an out-of-bag observation’s Webb11 feb. 2015 · The proximities originally formed a NxN matrix. After a tree is grown, put all of the data, both training and oob, down the tree.
