Independent validation as a validation method for classification

Quantitative and Computational Methods in Behavioral Sciences, 2023
The use of classifiers provides an alternative to conventional statistical methods. This involves using the accuracy with which data is correctly assigned to a given group by the classifier to apply tests to compare the performance of classifiers. The conventional validation methods for determining the accuracy of classifiers have the disadvantage that

Validation of a one-step reverse transcription PCR detection method for Tobamovirus maculatessellati, in tomato (Solanum lycopersicum L.) and pepper (Capsicum annuum L.)

Frontiers in Plant Science
The solanaceous-infecting tobamoviruses are closely related and hence it can be challenging to detect them using serological or molecular methods, particularly when present in a mixed infection.
