This is different from the case of DBR and BRGC encoding where the resultant length of the binary output of each dimension will be equivalent to the actual bit entropy offered by each dimension.
Therefore, given a specific entropy requirement L, for (A) BRGC or (B) DBR encoding-based discretization where n = I bits, we have
3, it is clear that all DBR and BRGC encoding-based discretization schemes exhibit a gradually deteriorating EER performance as the entropy requirement increases, due to their inability in preserving the separation among the feature points during the discrete-to-binary map.
