Passive-Aggressive Algorithm with Bias

Abstract (in Japanese) (See Japanese page) 
(in English) We consider online binary classi cation problems by using linear classi ers. Among online learning
algorithms for linear classi ers, Passive-Aggressive algorithm is very popular. In order to learn linear classi ers
with bias (constant term), Passive-Aggressive algorithm, like many typical online learning algorithms, extends the
instance space by adding an extra dimension corresponding to bias and its value is given as a parameter. But, in
general, it is not trivial to optimize the extra parameter so as to minimize cumulative losses. In this paper, we
propose a version of Passive-Aggressive algorithm which can deal with bias without the extra parameter to tune.
