Feature Selection Using Maximum Feature Tree Embedded with Mutual Information and Coefficient of Variation for Bird Sound Classification

Algorithm 3

ERFTN.

	Name: ERFTN (Eliminate Redundant Features based on Two Neighborhoods).
	Input: T: Max feature Tree by Algorithm BMFT, F: Features sorted with MICV method.
	Step:(1)Get the first element x in .(2), y is the adjacent vertices of x }.(3)Update by deleting all vertices in , that is .(4)Choose the next unvisited element as x.(5)Repeat (2) to (4), until all the elements in are visited.(6)Output as the final feature subset.
	Output:.
