Binary classification , Part 1

The problem of binary classification can be stated as follows. We have a random couple Z = (X ,Y ), where X ∈ Rd is called the feature vector and Y ∈ {−1,1} is called the label1. In the spirit of the modelfree framework, we assume that the relationship between the features and the labels is stochastic and described by an unknown probability distribution P ∈P (Z), where Z=Rd × {−1,1}. In these l...

Effects of obesity and weight changes on cardiac and vascular structure and function: does the clinical impact carry any weight?
