> Title: Embodied Multimodal Multitask Learning
>
> Abstract: Recent efforts on training visual navigation agents conditioned
> on language using deep reinforcement learning have been successful in
> learning policies for two multimodal tasks: learning to follow navigational
> instructions and embodied question answering. We aim to learn a multitask
> model capable of jointly learning both tasks, and transferring knowledge of
> words and their grounding in visual objects across tasks. The proposed
> model uses a novel Dual-Attention unit to disentangle the knowledge of
> words in the textual representations and visual objects in the visual
> representations, and align them with each other. This disentangled
> task-invariant alignment of representations facilitates grounding and
> knowledge transfer across both tasks. We show that the proposed model
> outperforms a range of baselines on both tasks in simulated 3D
> environments. We also show that this disentanglement of representations
> makes our model modular, interpretable, and allows for zero-shot transfer
> to instructions containing new words by leveraging object detectors.
