Indefinite Core Vector Machine

作者:

Highlights:

• Indefinite Core Vector Machine (iCVM) is proposed.

• Approximation concepts are provided leading to linear runtime complexity under moderate assumptions.

• Sparsification of iCVM is proposed showing that in many cases also a low memory complexity can be obtained with an acceptable loss in accuracy.

• The algorithm is compared to a number of related methods and multiple datasets showing competitive performance but with much lower computational and memory complexity.
