Stopping criterion for Algorithm 1 is SC > θ, where SC is computed as follows: The value of SC is expected to decrease due to a relatively large dip in the value of I(R, S) when Algorithm 1: IB inspired text segmentation Input : Joint distribution: p(R, C), Tradeoff parameter: β Output : Segmentation sequence: Update ∆F (s, s i−1 ) and ∆F (s, s i+2 ); 5 end more dissimilar clusters are merged.
sC provides strong clues to terminate the proposed IB approach.
