A Deep learning is a subset of machine learning (ML), which is a subset of artificial intelligence. B Architecture of an ML convolutional neural network (CNN) with two hidden layers. >3 layers qualifies as deep learning. C–E Logistic regression vs. CNN. Traditional cardiovascular risk estimates use logistic regression models, which excel when data is linearly separable (C) but not as well in complex situations (D). ML can generate more complex decision boundaries (E).
