Figure 5.

An example of IDyOT seqmentation. For illustrative clarity, as in Figure 4, M^δ,α is constructed statically post hoc, and not incrementally. The figure shows levels α and α+1 for an example sequence similar to that in Figure 3. H is not calculable for a symbol which has not been encountered as the first element of a bigram, so no value can be given for the last symbol. Note that the sequence “ee” arises more than once: this is enough to suggest that it might be treated as a segment at a higher level. Note also that ${\overline{h}}^{\delta ,\alpha }$ of layer α+1 is lower that of layer α, and that layer α is impervious to more grouping under the current definition of ${\Delta }_{\tau }^{\alpha }$, so the process stops.
