Abstract: Long Short-Term Memory (LSTM) networks have been successfully applied to a number of sequence learning problems but they lack the design flexibility to model multiple view interactions, limiting their ability to exploit multi-view relationships. In this paper, we propose a Multi-View LSTM (MV-LSTM), which explicitly models the view-specific and cross-view interactions over time or structured outputs. We evaluate the MV-LSTM model on four publicly available datasets spanning two very different structured learning problems: multimodal behaviour recognition and image captioning. The experimental results show competitive performance on all four datasets when compared with state-of-the-art models.
