Artificial intelligence (AI) systems are increasingly central to critical infrastructure, business operations, and national ...

An AI model is only as good as the data it’s trained on. Without a large volume of relevant and accurate training data, the model will either not learn what it’s supposed to, or it will learn ...

We applied the model to the external validation data to evaluate discrimination performance (AUC) and calibrated to US SEER. Results. Using 3 years of previous mammogram images available at the ...

Data modeling, at its core, is the process of transforming raw data into meaningful insights. It involves creating representations of a database’s structure and organization. These models are ...

In the validation data set, the predictive model achieved an AUC of 0.987 (95% CI, 0.974 to 0.999; Fig 4A). With a cutoff score of 0.53, the model effectively differentiated between patients with PDAC ...
