Lung Nodule Classification by the Combination of Fusion Classifier and Cascaded Convolutional Neural Networks

2017 · arXiv (Cornell University)

Lung nodule classification is a class imbalanced problem, as nodules are found with much lower frequency than non-nodules. In the class imbalanced problem, conventional classifiers tend to be overwhelmed by the majority class and ignore …

DomainDynamics: Lifecycle-Aware Risk Timeline Construction for Domain Names

2024 · arXiv (Cornell University)

The persistent threat posed by malicious domain names in cyber-attacks underscores the urgent need for effective detection mechanisms. Traditional machine learning methods, while capable of identifying such domains, often suffer from high false positive and …
