Side-Tuning: Network Adaptation via Additive Side Networks

ICLR 2020

When training a neural network for a desired task, one may prefer to adapt a pretrained network rather than start with a randomly initialized one -- due to lacking enough training data, performing lifelong learning where the system has to learn a new task while being previously trained for other tasks, or wishing to encode priors in the network via preset weights.

Improving the Generalization of Visual Navigation Policies using Invariance Regularization

ICLR 2020

The results of this method, called invariance regularization, show an improvement in the generalization of policies to environments not seen during training.

Audio-Visual Embodied Navigation

24 Dec 2019

Moving around in the world is naturally a multisensory experience, but today's embodied agents are deaf - restricted to solely their visual perception of the environment.

Generating Robust Supervision for Learning-Based Visual Navigation Using Hamilton-Jacobi Reachability

20 Dec 2019

In this paper, we present a novel Hamilton-Jacobi (HJ) reachability-based method to generate supervision for the CNN for waypoint prediction.

Are We Making Real Progress in Simulated Environments? Measuring the Sim2Real Gap in Embodied Visual Navigation

13 Dec 2019

We find that SRCC for Habitat as used for the CVPR19 challenge is low (0. 18 for the success metric), which suggests that performance improvements for this simulator-based challenge would not transfer well to a physical robot.

Unsupervised Reinforcement Learning of Transferable Meta-Skills for Embodied Navigation

18 Nov 2019

Visual navigation is a task of training an embodied agent by intelligently navigating to a target object (e. g., television) using only visual observations.

Help, Anna! Visual Navigation with Natural Multimodal Assistance via Retrospective Curiosity-Encouraging Imitation Learning

IJCNLP 2019

An agent solving tasks in a HANNA environment can leverage simulated human assistants, called ANNA (Automatic Natural Navigation Assistants), which, upon request, provide natural language and visual instructions to direct the agent towards the goals.
