Bearing Fault Diagnosis Based on Collaborative Representation Using Projection Dictionary Pair

Algorithm 1

Classification algorithm.

	Input: dictionary and threshold ρ
	Main procedure:
(1)	Normalize the columns of to make them regularize ( norm)
(2)	Let q be encoded on C through
(3)	Calculate residuals
(4)	Identify the class of q by using TD , where TD (q) is the label of identified class to which the sample q belongs.
	Output: identified class to which q belongs.
