  2. Introduction • Discrete Bit Selection • Use bitlevel heuristics to split rules efficiently • Adopt adaptive flat data structures to guarantee fast searching with low memory requirement

  3. DBS Algorithm (1/5) • E-bit

  4. DBS Algorithm (2/5)

  5. DBS Algorithm (3/5) • Mask Vector Generation • Our motivation is to select the most effective mask vector which can split R into subsets as small as possible. • Sequential Forward Selection (SFS) • Heuristic Swap (HS)
