  abstract =     "Rolling-element bearings are widely used in various
                 mechanical and electrical systems. A reliable bearing
                 fault diagnostic technique is critically needed in
                 industries to recognize a bearing fault at its early
                 stage so as to prevent system's performance degradation
                 and malfunction. In this work, a genetic programming
                 based feature reconstruction approach is proposed for
                 bearing fault diagnostics. A new fitness measure is
                 proposed to improve the GP operations in feature
                 formulation. The original features are from the
                 modified kurtosis ratio and the one-scale wavelet
                 analysis. Investigation results show that the proposed
                 method is an effective feature formulation tool; the
                 reconstructed features are more robust against the
                 variations in bearing geometry and operating
                 conditions. The corresponding fault diagnostic
                 reliability can be enhanced significantly. As a result,
                 this work provides a promising technique and tool for
                 bearing condition monitoring for real-world
