Enabling Health Monitoring Approach Based on Vibration Data for Accurate Prognostics
TLDR
This paper contributes a new approach for feature extraction/selection: The extraction is based on trigonometric functions and cumulative transformation, and the selection is performed by evaluating feature fitness using monotonicity and trendability characteristics. Expand

SW-ELM: A summation wavelet extreme learning machine algorithm with a priori parameter initialization
TLDR
We propose a new structure of connectionist network, the Summation Wavelet Extreme Learning Machine (SW-ELM) that enables good accuracy and generalization performances, while limiting the learning time and reducing the impact of a random initialization procedure. Expand
