Towards this end, an innovative adaptive learning-by-examples (LBE) technique has been developed. It is based on the innovative combination of a Partial Least Squares (PLS) features extraction technique and an adaptive sampling strategy to generate optimal training sets. Such information is used to train a Support Vector Regressor (SVR) in order to build a fast but accurate predictor of the crack descriptors staring from previously-unseen ECT measurements during the on-line testing phase. The proposed LBE inversion strategy, previously validated on numerical simulations, is here tested against real laboratory-controlled experimental data coming from the World Federation of NDE Centers (FNDEC) “2008 Eddy Current Benchmarks”. publisher: University of Trento date: 2016 type: Monograph type: NonPeerReviewed format: text language: en identifier: http://www.eledia.org/students-reports/716/1/An%20Innovative%20Adaptive%20LBE%20Technique%20for%20Real-Time%20Crack%20Characterization_%20An%20Experimental%20Study.pdf identifier: Salucci, M. and Anselmi, N. and Oliveri, G. and Massa, A.
