MAGID: An Automated Pipeline for Generating Synthetic Multi-modal Datasets

NAACL 2024long

Development of multimodal interactive systems is hindered by the lack of rich, multimodal (text, images) conversational data, which is needed in large quantities for LLMs. Previous approaches augment textual dialogues with retrieved images, posing privacy, diversity, and quality constraints. In this…

Locally Persistent Exploration in Continuous Control Tasks with Sparse Rewards

ICML 2021spotlight

A major challenge in reinforcement learning is the design of exploration strategies, especially for environments with sparse reward structures and continuous state and action spaces. Intuitively, if the reinforcement signal is very scarce, the agent should rely on some form of short-term memory in o…
