Iteration of Thought: Leveraging Inner Dialogue for Autonomous Large Language Model Reasoning

Abstract:

The paper introduces the Iteration of Thought (IoT) framework, designed to enhance the responses of large language models (LLMs) by leveraging an iterative approach through an Inner Dialogue Agent (IDA) that generates context-specific prompts. This framework contrasts with static methods like Chain of Thought (CoT) by adapting reasoning paths dynamically based on evolving contexts, minimizing the need for human intervention.

Key Components:

1. Inner Dialogue Agent (IDA): Generates instructive prompts tailored to the current response iteration.
2. LLM Agent (LLMA): Processes the prompts to refine responses.
3. Iterative Prompting Loop: Facilitates conversation between the IDA and LLMA to produce more thoughtful responses.

Variants of the Framework:

• Autonomous Iteration of Thought (AIoT): The LLM autonomously decides when to stop iterating.
• Guided Iteration of Thought (GIoT): A fixed number of iterations is enforced.

Findings:

• The IoT framework shows significant performance improvements across various complex reasoning tasks, including:
• GIoT outperformed AIoT in certain tasks, while AIoT excelled in others, indicating that iteration-terminating mechanisms play a crucial role in performance.
• IoT demonstrates conceptual transparency and explainability, allowing for insights into the model's reasoning process and self-correction capabilities.

Conclusion and Future Work:

The IoT framework provides a promising approach to refining LLM responses autonomously while maintaining adaptability. Future directions include exploring the scale and diversity of the IDA’s knowledge base, utilizing specialized language models, and addressing challenges such as hallucination and premature iteration termination.

To CoT or not to CoT? Chain-of-thought helps mainly on math and symbolic reasoning

Abstract: This study investigates the effectiveness of Chain-of-Thought (CoT) prompting in large language models (LLMs) across various tasks. Through a quantitative meta-analysis of over 100 studies and evaluations of 20 datasets on 14 models, the authors find that CoT significantly enhances performance primarily on math and logic tasks, with minimal gains on other types of tasks.

Key Findings:

• Performance Benefits: CoT is especially beneficial for tasks involving symbolic operations, as evidenced by its strong performance in math and formal logic. In contrast, tasks without symbolic manipulation show negligible improvement.
• Execution vs. Planning: The study distinguishes between the planning and execution phases of problem-solving, noting that CoT mainly aids in the execution of symbolic steps. However, it performs poorly compared to symbolic solvers for complex reasoning tasks.
• Limitations of CoT: While CoT is a powerful tool, its effectiveness diminishes for non-symbolic tasks, raising questions about whether specific modes of deliberation could enhance its utility.
• Future Directions: The authors suggest a shift away from prompt-based CoT towards new paradigms like search mechanisms or interacting agents to broaden its application across various NLP tasks.

Conclusion: CoT remains a valuable technique for enhancing reasoning in LLMs, particularly for math and logic problems. However, there is a need for further research into more sophisticated approaches that leverage intermediate computations to improve performance across a wider range of applications.

• Semantic Memory: Holds general knowledge and external information sources (e.g., APIs, documentation).
• Episodic Memory: Captures context-specific information and past experiences to inform decision-making.
• Procedural Memory: Contains implicit and explicit knowledge enabling agents to operate autonomously.

Action:

• Differentiates between:
• Internal Actions: Such as reasoning, retrieval, and learning, which occur within the agent.
• External Actions: Interactions with the external environment, including dialogues with users and other agents.

Moshi: a speech-text foundation model for real-time dialogue

Moshi is introduced as a novel speech-text foundation model designed for real-time, full-duplex spoken dialogue. Traditional spoken dialogue systems rely on separate components for voice activity detection, speech recognition, and text-to-speech conversion, leading to issues like latency and loss of non-linguistic information. Moshi addresses these challenges by treating spoken dialogue as speech-to-speech generation, allowing for a more natural conversational experience.

Key Features of Moshi

1. Speech-to-Speech Generation: Unlike conventional systems that depend on intermediate text, Moshi generates speech directly as tokens from a neural audio codec, accommodating overlapping speech and interruptions.
2. Inner Monologue Method: This innovative approach involves predicting time-aligned text tokens before generating audio tokens, enhancing the linguistic quality of the output and enabling streaming speech recognition and text-to-speech functionalities.
3. Real-Time Performance: Moshi achieves a theoretical latency of 160ms, translating to approximately 200ms in practice, allowing for seamless multi-turn conversations.

Conclusion: Moshi represents a significant advancement in real-time spoken dialogue systems, integrating multiple technologies into a cohesive framework capable of managing complex conversations. By releasing both Moshi and its underlying neural audio codec, Mimi, the authors aim to promote further exploration and application development in the field of speech-to-speech models. The methods introduced in this research, particularly the Inner Monologue and multi-stream modeling techniques, are anticipated to have broad implications beyond dialogue modeling.
