AIGeN: An Adversarial Approach for Instruction Generation in VLN

no code implementations15 Apr 2024 Niyati Rawal, Roberto Bigazzi, Lorenzo Baraldi, Rita Cucchiara

VLN is a challenging task that involves an agent following human instructions and navigating in a previously unknown environment to reach a specified goal.

Mapping High-level Semantic Regions in Indoor Environments without Object Recognition

no code implementations11 Mar 2024 Roberto Bigazzi, Lorenzo Baraldi, Shreyas Kousik, Rita Cucchiara, Marco Pavone

Robots require a semantic understanding of their surroundings to operate in an efficient and explainable way in human environments.

Embodied Agents for Efficient Exploration and Smart Scene Description

no code implementations17 Jan 2023 Roberto Bigazzi, Marcella Cornia, Silvia Cascianelli, Lorenzo Baraldi, Rita Cucchiara

The development of embodied agents that can communicate with humans in natural language has gained increasing interest over the last years, as it facilitates the diffusion of robotic platforms in human-populated environments.

Spot the Difference: A Novel Task for Embodied Agents in Changing Environments

no code implementations18 Apr 2022 Federico Landi, Roberto Bigazzi, Marcella Cornia, Silvia Cascianelli, Lorenzo Baraldi, Rita Cucchiara

To make a step towards this setting, we propose Spot the Difference: a novel task for Embodied AI where the agent has access to an outdated map of the environment and needs to recover the correct layout in a fixed time budget.

Focus on Impact: Indoor Exploration with Intrinsic Motivation

1 code implementation14 Sep 2021 Roberto Bigazzi, Federico Landi, Silvia Cascianelli, Lorenzo Baraldi, Marcella Cornia, Rita Cucchiara

The proposed exploration approach outperforms DRL-based competitors relying on intrinsic rewards and surpasses the agents trained with a dense extrinsic reward computed with the environment layouts.

Explore and Explain: Self-supervised Navigation and Recounting

no code implementations14 Jul 2020 Roberto Bigazzi, Federico Landi, Marcella Cornia, Silvia Cascianelli, Lorenzo Baraldi, Rita Cucchiara

In this paper, we devise a novel embodied setting in which an agent needs to explore a previously unknown environment while recounting what it sees during the path.
