Improving Reasoning Performance in Large Language Models via Representation Engineering

ICLR 2025poster

Recent advancements in large language models (LLMs) have resulted in increasingly anthropomorphic language concerning the ability of LLMs to reason. Whether \textit{reasoning} in LLMs should be understood to be inherently different is, however, widely debated. We propose utilizing a representation e…

Research Community Perspectives on “Intelligence” and Large Language Models

ACL 2025finding

Despite the widespread use of ‘artificial intelligence’ (AI) framing in Natural Language Processing (NLP) research, it is not clear what researchers mean by ”intelligence”. To that end, we present the results of a survey on the notion of ”intelligence” among researchers and its role in the research…

Prioritized Soft Q-Decomposition for Lexicographic Reinforcement Learning

ICLR 2024poster

Reinforcement learning (RL) for complex tasks remains a challenge, primarily due to the difficulties of engineering scalar reward functions and the inherent inefficiency of training models from scratch. Instead, it would be better to specify complex tasks in terms of elementary subtasks and to reuse…

Designing a Personality-Driven Robot for a Human-Robot Interaction Scenario

ICRA 2019poster

In this paper, we present an autonomous AI system designed for a Human-Robot Interaction (HRI) study, set around a dice game scenario. We conduct a case study to answer our research question: Does a robot with a socially engaged personality lead to a higher acceptance than a competitive personality?…

Generating Multiple Objects at Spatially Distinct Locations

ICLR 2019poster

Recent improvements to Generative Adversarial Networks (GANs) have made it possible to generate realistic images in high resolution based on natural language descriptions such as image captions. Furthermore, conditional GANs allow us to control the image generation process through labels or even nat…
