Table 1 Confusion matrix
Manually marked formula names | Formula name recognized by the algorithm | |
|---|---|---|
Consistent with manual making | Inconsistent with manual marking | |
Recognized by the algorithm correctly | \({f}_{11}=\sum\limits_{n=1}^{N}\left|A\cap B\right|\) | \({f}_{12}=\sum\limits_{n=1}^{N}\left|B-\left(A\cap B\right)\right|\) |
Not recognized by the algorithm | \({f}_{21}=\sum\limits_{n=1}^{N}\left|A-\left(A\cap B\right)\right|\) | - |
