函数：

ee.Classifier.smileRandomForest(numberOfTrees, variablesPerSplit, minLeafPopulation, bagFraction, maxNodes, seed)

Creates an empty Random Forest classifier.

Arguments:

numberOfTrees (Integer):

The number of decision trees to create.

variablesPerSplit (Integer, default: null):

The number of variables per split. If unspecified, uses the square root of the number of variables.

minLeafPopulation (Integer, default: 1):

Only create nodes whose training set contains at least this many points.

bagFraction (Float, default: 0.5):

The fraction of input to bag per tree.

maxNodes (Integer, de
