False Negative Rate
False negative rate (FNR) refers to the proportion of actual positives incorrectly identified as negatives, a critical metric across diverse fields demanding high-accuracy classification. Current research focuses on improving FNR estimation and mitigation, particularly in applications with asymmetric costs of false positives and negatives, such as fraud detection and anomaly detection in time-series data. This involves developing novel algorithms, including variational autoencoders and methods leveraging soft labels, to refine model training and reduce bias in negative sampling strategies. Accurate FNR estimation is crucial for optimizing model performance and ensuring reliable decision-making in various applications, from e-commerce to wildfire detection and robotics.
