Algorithm 1 Development of feature vectors X and Y

Input: $Open{D}^a, Firstview{D}^a, Submission{D}^s, Deadlin{e}^s$, S, A

Output: Feature vector X and Y

1: Initialize j = |S|, i = |A|

2:  while n < j do

3:    while m < i do

4:     $x_{nm}\left[v_1\right]=\frac{Deadlin{e}^m–Submission{D}_m^n}{Deadlin{e}^m–Open{D}^m}$

5:     $x_{nm}\left[v_2\right] = \frac{Firstview{D}_m^n– Open{D}^m}{Deadlin{e}^m– Open{D}^m}$

6:     if $x_{nm}\left[v_1\right]$ < = 0 then

7:       $y_{nm}\left[w_1\right]$ = 0

8:     else

9:       $y_{nm}\left[w_1\right]$ = 1

10:     if $x_{nm}\left[v_2\right]$ = > median $x_{nm}\left[v_2\right]$ then

11:       $y_{nm}\left[w_2\right]$ = 0

12:     else

13:       $y_{nm}\left[w_2\right]$ = 1

14:     end if

15:   end while

16: end while

17: return Feature vector X and Y
