• Abstract: This paper addresses a challenging interactive task learning scenario we call rearrangement under unawareness: to manipulate a rigid-body environment in a context where the agent is unaware of a concept that is key to solving the instructed task. We propose SECURE, an interactive task learning framework designed to solve such problems. It uses embodied conversation to fix its deficient domain model -- through dialogue, the agent discovers and then learns to exploit unforeseen possibilities. In particular, SECURE learns from the user's embodied corrective feedback when it makes a mistake, and it makes strategic dialogue decisions to reveal useful evidence about novel concepts for solving the instructed task. Together, these abilities allow the agent to generalise to subsequent tasks using newly acquired knowledge. We demonstrate that learning to solve rearrangement under unawareness is more data efficient when the agent is semantics-aware -- that is, during both learning and inference it augments the evidence from the user's embodied conversation with its logical consequences, stemming from semantic analysis.

• Interactive Agents to Overcome Ambiguity in Software Engineering [61.40183840499932]
  AI agents are increasingly being deployed to automate tasks, often based on ambiguous and underspecified user instructions. Making unwarranted assumptions and failing to ask clarifying questions can lead to suboptimal outcomes. We study the ability of LLM agents to handle ambiguous instructions in interactive code generation settings by evaluating proprietary and open-weight models on their performance.

  We propose a novel method to train AI agents to incorporate knowledge and skills for multiple tasks without the need for cumbersome note systems or prior high-quality demonstration data. Our approach employs an iterative process where the agent collects new experiences, receives corrective feedback from humans in the form of hints, and integrates this feedback into its weights. We demonstrate the efficacy of our approach by implementing it in a Llama-3-based agent which, after only a few rounds of feedback, outperforms advanced models GPT-4o and DeepSeek-V3 in a taskset.

  We propose a novel interaction framework called Semantic Interactive Learning for the text domain. We frame the problem of incorporating constructive and contextual feedback into the learner as a task to find an architecture that enables more semantic alignment between humans and machines. We introduce a technique called SemanticPush that is effective for translating conceptual corrections of humans to non-extrapolating training examples.
