The Nature Of Statistical Learning Theory Official

SLT proves that for a machine to generalize well, its capacity must be controlled relative to the amount of available training data. This led to the principle of , which balances the model's complexity against its success at fitting the training data. From Theory to Practice: Support Vector Machines

A mechanism that provides the "target" or output value for each input vector. The Nature of Statistical Learning Theory

A source of data that produces random vectors, usually assumed to be independent and identically distributed (i.i.d.). SLT proves that for a machine to generalize

The "nature" of this field is essentially the study of the gap between these two. If a model is too simple, it fails to capture the data's structure (underfitting). If it is too complex, it "memorizes" the noise in the training set (overfitting), leading to low empirical risk but high expected risk.
