Inspired by the above discovery, accordingly, we convert all the binaryvalue features into their corresponding realvalued features.
compared with the original joint model, the new joint-plus approach does not show much improvement, regardless of the significant improvement made by the discriminative-plus model, as the additional benefit generated by the discriminative-plus model has already covered by the generative approach (Among the 6,965 error words corrected by the discriminative-plus model, 6,292 (90%) of them are covered by the generative model).
