• Title: Methodology to Create Analysis-Naive Holdout Records as well as Train and Test Records for Machine Learning Analyses in Healthcare
• Authors: Michele Bennett, Mehdi Nekouei, Armand Prieditis Rajesh Mehta, Ewa Kleczyk, Karin Hayes
• Abstract summary: The purpose of the holdout sample is to preserve data for research studies that will be analysis-naive and randomly selected from the full dataset. The methodology suggested for creating holdouts is a modification of k-fold cross validation, which takes into account randomization and efficiently allows a three-way split.

• Abstract: It is common for researchers to holdout data from a study pool to be used for external validation as well as for future research, and the same desire is true to those using machine learning modeling research. For this discussion, the purpose of the holdout sample it is preserve data for research studies that will be analysis-naive and randomly selected from the full dataset. Analysis-naive are records that are not used for testing or training machine learning (ML) models and records that do not participate in any aspect of the current machine learning study. The methodology suggested for creating holdouts is a modification of k-fold cross validation, which takes into account randomization and efficiently allows a three-way split (holdout, test and training) as part of the method without forcing. The paper also provides a working example using set of automated functions in Python and some scenarios for applicability in healthcare.

  We propose a training-required and training-free test-time adaptation framework. We maintain a light-weight key-value memory for feature retrieval from instance-agnostic historical samples and instance-aware boosting samples. We theoretically justify the rationality behind our method and empirically verify its effectiveness on both the out-of-distribution and the cross-domain datasets.

We estimate key performance metrics such as false positive rate, false negative rate, and priors in scenarios where no ground truth is available. We extend this paradigm for handling online data, opening up new possibilities for dynamic data environments.
