• Title: MindGames: Targeting Theory of Mind in Large Language Models with Dynamic Epistemic Modal Logic
• Authors: Damien Sileo and Antoine Lernould
• Abstract summary: Theory of Mind (ToM) is a critical component of intelligence but its assessment remains the subject of heated debates. Here, we leverage dynamic epistemic logic to isolate a particular component of ToM and to generate controlled problems. Our findings indicate that some language model scaling does not consistently yield results better than random chance.

• Abstract: Theory of Mind (ToM) is a critical component of intelligence but its assessment remains the subject of heated debates. Prior research applied human ToM assessments to natural language processing models using either human-created standardized tests or rule-based templates. However, these methods primarily focus on simplistic reasoning and require further validation. Here, we leverage dynamic epistemic logic to isolate a particular component of ToM and to generate controlled problems. We also introduce new verbalization techniques to express these problems in English natural language. Our findings indicate that some language model scaling (from 70M to 6B and 350M to 174B) does not consistently yield results better than random chance. While GPT-4 demonstrates superior epistemic reasoning capabilities, there is still room for improvement. Our code and datasets are publicly available (https://huggingface.co/datasets/sileod/mindgames , https://github.com/sileod/llm-theory-of-mind )

  Recently developed large language models (LLMs) have been shown to perform remarkably well on a wide range of language understanding tasks. But, can they really "reason" over the natural language? This question has been receiving significant research attention and many reasoning skills such as commonsense, numerical, and qualitative have been studied.

  Program-of-Thought (PoT) replaces natural language-based Chain-of-Thought (CoT) as the most popular method in Large Language Models. Using PoT introduces more reasoning errors, such as incorrect formulas or flawed logic, compared to CoT. We propose Human-Think Language (HTL), which leverages a suite of strategies that help integrate PoT and CoT.

  Theory of Mind (ToM) is an essential ingredient for developing machines with human-level social intelligence. Recent machine learning models, particularly large language models, seem to show some aspects of ToM understanding. Human ToM, on the other hand, is more than video or text understanding. People can flexibly reason about another person's mind based on conceptual representations extracted from any available data.

  Existing techniques for training language models can be misaligned with the truth. We propose directly finding latent knowledge inside the internal activations of a language model in a purely unsupervised way. We show that despite using no supervision and no model outputs, our method can recover diverse knowledge represented in large language models.

We show the effect of training with auxiliary text LMs, multitask learning objectives, and auxiliary articulatory features.
