Reduction in number of constraints in max-margin early event detectors

作者:

Highlights:

• The proposed approach aims to reduce the number of constraints generated in MMED [M. Hoai, F. Torre, Max margin early event detectors, International Journal of Computer Vision 107(2) (2014) 191 202].

• The number of constraints is reduced from O(IL3) to O(IL2) where I is the training sample size and L is the length of instance time series.

• Mathematical proof of the correctness of the proposed reduction method is provided.
