Local Online Fusion Discretizer (LOFD)

Local Online Fusion Discretizer (LOFD)

LOFD  is an online, self-adaptive discretizer for streaming classification. It smoothly adapts its interval limits reducing the negative impact of shifts and analyze interval labeling and interaction problems in data streaming. Interaction discretizer-learner is addressed by providing 2 alike solutions. The algorithm generates an online and self-adaptive discretization solution for streaming classification which aims at reducing the negative impact of fluctuations in evolving intervals.
