Can KRLS be used for classification?

[AmirhosseinModabbernia]

Hi there,

Can this algorithm be used for classifying a binary variable or is it only suitable for regression of continuous outcomes?

Yes, KRLS can be used with a binary dependent variable (see Section 6 of Hainmueller and Hazlett <https://www.jstor.org/stable/pdf/24573219.pdf?casa_token=Exo8zHuL4zcAAAAA:ffH6wLZMNRqPItHsWaHNaH5EtASDZqDOktUXdJ9uU2V41DDKX21FEkOVlGhzreFzPRhUuFJpq8ZAaWHEgZ_5LTD01L20nCCWi6FpeJJ6R92vVq8UYA> for an example). However, you may also want to look at KRLS-Logit, which is a work-in-progress implementation of logistic regression in the KRLS framework (see here <https://github.com/lukesonnet/KRLS> for details).
