Webwork. Section 4 presents an analysis of false match rate (FMR) and false non-match rate (FNMR) as a function of the matcher decision threshold. Section 5 describes differences in the impostor and genuine distributions between cohorts. Section 6 considers how differences in image quality between cohorts are related to differences in accuracy. WebApr 2, 2024 · The -match and -notmatch operators return any matching and non-matching members respectively. However, the -like and -notlike operators return the members as strings. The string returned for a member of the collection by -like and -notlike is the string the operator used for the comparison and is obtained by casting the member to a string. bank mandiri cirebon ciledug kabupaten cirebon jawa barat
