In DuoRec, a model-level augmentation is proposed based on Dropout to enable better semantic preserving.

NettetThen the acoustic and linguistic embeddings are simul- taneously aligned through cross-modal contrastive learning and fed into an intent classier to predict the intent labels. The model is optimized with two losses: contrastive learn- ing loss from multi-modal embeddings and intent classication loss from the predictions and ground truths.
