Large Language Models Self-Compose Reasoning Structures – Ajith Prabhakar’s Weblog



In this blog we will look at a research paper titled “Self-Discover: Large Language Models Self-Compose Reasoning Structures”. which discusses the implementation of a cognitive reasoning structure to LLM to improve its performance.

Large language models (LLM) have become very powerful with the introduction of the Transformer architecture. These models can generate high-quality text based on the instructions given to them. However, you need to use an effective prompting strategy to get the best results from these models.

According to researchers, each task requires a specific reasoning structure. If we can identify this structure, we can significantly enhance the efficiency of solving that particular task. This approach differs from methods such as Chain of Thought (CoT), which may not be as effective across various types of reasoning tasks.

Thus they introduces a framework that is influenced by how humans think and intend to recognize and utilize the inherent reasoning structure of a task. This means breaking down tasks into smaller subtasks, applying critical thinking, and solving the task based on the discovered reasoning structure.

Self-Discover Framework

This research draws inspiration from humans’ cognitive processes for reasoning and problem-solving by creating a framework that aims to enhance the reasoning abilities of Large Language Models (LLMs) by enabling them to autonomously identify and utilize the distinctive, inherent reasoning structures specific to individual tasks.

The operation of the Self-Discover framework is divided into two stages. 

Stage 1 – Discover Reasoning Structure on Task-Level 

During this first stage, the Self-Discover process identifies the unique reasoning structure of a given task. This is done by using a set of atomic reasoning modules, such as “breaking down into subtasks” and “critical thinking,” to generate a customized reasoning structure that is tailored to the given task. This stage establishes the foundation for how the task will be approached and solved, utilizing the strengths of multiple reasoning modules rather than relying on a single predefined method. 

Stage 1 consists of three different actions. 

1 – SELECT 

In select action, the model chooses the relevant reasoning modules for task-solving from the set of reasoning module descriptions; 
For example, Pick “reflective thinking” if the task is to identify first-principle theories on science problems, or use “creative thinking” to generate a novel continuation to a story. 

2 – ADAPT 

 The descriptions of selected reasoning modules are rephrased to be more specific to the given task. 
For example,  “break the problem into sub-problems” to “calculate each arithmetic operation in order” for arithmetic problems.

3 – IMPLEMENT

The adapted reasoning descriptions are implemented into a structured, actionable plan to solve the task by following the structure.

Stage 2 – Applying Discovered Structures to Solve Tasks   

After identifying the intrinsic reasoning structure, the LLM (Language Learning Model) solves the task instances by following the self-discovered structure. During this stage, the model emphasizes the practical application of the identified reasoning structure, allowing it to tackle the task efficiently and effectively. In simple words, the LLM uses the discovered reasoning path to arrive at the solution, making the task-solving process smoother and quicker.

The methodology of SELF-DISCOVER imitates the human approach to problem-solving by identifying and applying the most suitable reasoning strategies. This not only enhances the problem-solving abilities of LLMs, but also makes them more efficient, interpretable, and aligned with the intrinsic nature of the tasks. This approach can be used to leverage LLMs in complex reasoning and problem-solving scenarios.
