Algorithm 1:Max-Correlation and Max-Independence Rate (MCIR)

Input: Information system $(U, C ⋃ D)$ .

Output: An attribute reduction set $B$ .

1:
compute $M H (C; D)$
2:
$F e a t \Leftarrow C$ ,
3:
$B \Leftarrow \underset{a_{j} \in F e a t}{arg} max ∣ M H (D; B) - M H (D; B ⋃ a_{j}) ∣$
4:
$F e a t \Leftarrow C - B$ ,

7:
if $∣ F e a t ∣ = 0$ then
8:
$B \Leftarrow B$

10:
$a_{j} \Leftarrow \underset{a_{j} \in F e a t}{arg} max J_{M C I R} (a_{j})$
11:
$B \Leftarrow B + {a_{j}}$
12:
