Therefore it is necessary for a literature survey to access the state of the art development in partial discharge classification.
Past research work in partial discharge classification varies greatly in terms of classification techniques used, choice of feature extraction, denoising method, training process, artificial defects created for training purposes and performance assessment.
This study suggests a feature extraction and classification algorithm for surface discharge classification, which when combined together reduced the dimensionality of the feature space to a manageable dimension, by "marrying" the wavelet to radial basis function neural network very high levels of classification are achieved.
This paper introduces the first application of feature extraction and machine learning to electromagnetic interference (EMI) signals for discharge sources classification in high voltage power generating plants.
Qualifying surgical cases were determined based on a review of discharge International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes.
The Charlson Comorbidity Index, an aggregate comorbidity score, was calculated using discharge International Classification of Diseases, 9 th Revision, Clinical Modification (ICD-9-CM) codes for comorbid conditions [ 18].
The re-admission/re-hospitalization AMI outcome was based on a primary discharge International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code of 410.XX for any hospitalization within the VA.
Daily visit totals of discharge International Classification of Diseases, 9th Revision codes of gastroenteritis or diarrhea were collected along with daily rainfall totals during the study period from 2002 to 2007.
A patient was determined to have severe coccidioidomycosis if he was in the hospital for >10 days during which all hospital discharge International Classification of Disease, Ninth Revision (ICD-9) codes indicated nondisseminated coccidioidomycosis (ICD-9 codes 114.0 or 114.4 114.9).
AHF diagnosis was identified as hospitalization with a primary or secondary discharge International Classification of Diseases, 9th Edition (ICD-9) code for AHF (428.xx, 398.91, 402.x1, 404.x1, 404.x3, 415.0, 417.x, 425.x, 429.0, 429.0, 429.1, or discharge diagnosis-related group of 127, 291, 292, and 293).
