Hello,

The reason I employed rounding is for the fact that it is unlikely that a model outputing discrete values would be able to exactly output, say [1, 0, 1]. Typically, these values are approached if an iterative algorithm is used, and a typical output would be something like [0.99, 0.001, 0.999], etc.. For this reason, rounding them to the nearest integer and then comparing them with the true outputs is more convienent for calcualting accuracy.
