Dimensionality reduction is a crucial task in machinery fault diagnosis.
Recently, as a popular dimensional reduction technology, manifold learning has been successfully used in many fields.
However, most of these technologies are not suitable for the task, because they are unsupervised in nature and fail to discover the discriminate structure in the data.
To overcome these weaknesses, kernel local linear discriminate (KLLD) algorithm is proposed.
KLLD algorithm is a novel algorithm which combines the advantage of neighborhood preserving projections (NPP), Floyd, maximum margin criterion (MMC), and kernel trick.
KLLD has four advantages.
First of all, KLLD is a supervised dimension reduction method that can overcome the out-of-sample problems.
Secondly, short-circuit problem can be avoided.
Thirdly, KLLD algorithm can use between-class scatter matrix and inner-class scatter matrix more efficiently.
Lastly, kernel trick is included in KLLD algorithm to find more precise solution.
The main feature of the proposed method is that it attempts to both preserve the intrinsic neighborhood geometry of the increased data and exact the discriminate information.
Experiments have been performed to evaluate the new method.
The results show that KLLD has more benefits than traditional methods.
