TABLE VI.

Feature quality before and after joint training. The format of results for before joint training means the ACC of supervised / unsupervised / reliable labels, for after joint training means the ACC of supervised / unsupervised. The supervised results were obtained by training a linear classifier while fixing the feature model.
