BoostStep: Boosting mathematical capability of Large Language Models via improved single-step reasoning

Hi, and welcome to another episode where we explore how artificial intelligence is shaping our daily lives. Today, we’re talking about something you’ve probably done before: using ChatGPT to solve your math homework. Maybe more often than you’d care to admit to your teacher, advisor—or even your crush!

But hey, no judgment here. Instead, we’re diving into a fascinating article on improving how AI handles math problems. It might sound a bit complex, but stick with me. By the end of this episode, you’ll have a clear understanding of the main ideas.

Basic Strategies and the Challenge of "Conquering"

Let’s start with two approaches you might use when asking ChatGPT for help with a trigonometry problem.

The first method is straightforward: write out the problem and ask for the solution. This traditional approach often falls short, as you may have experienced.

The second method is more advanced and probably familiar: asking the model to break the problem down step by step. In the world of algorithms and problem-solving, this is called "Divide and Conquer."

Here’s how it works in a math context:

  1. Identify a formula that matches the problem.

  2. List possible values that make sense.

  3. Calculate and test which value satisfies the problem’s conditions.

“Divide” means planning the process. “Conquer” means executing each step correctly.

According to the article, most errors in math-solving by AI models like ChatGPT occur during the "Conquer" phase. In fact, 92.8% of mistakes happen here.

Solution 1: A Granular Database of Solved Problems

This leads us to the article’s first big idea: a granular database of solved problems.

Why is this important? Imagine two problems that look completely different but share one critical step. A granular database helps identify and reuse those shared steps, improving both accuracy and efficiency.

The researchers tested two methods for creating this database:

  1. Grammatical separation: Splitting solved problems into steps based on punctuation.

  2. AI-driven separation: Using GPT-4 to break problems into steps through carefully crafted prompts.

The AI-based approach was more effective. They validated this by applying the methods to a dataset called PRM800K and solving problems from well-known benchmarks like AMC 12, AMC 10, and MATH. The results? The AI-driven method outperformed grammatical separation with improvements of 6.5%, 2.3%, and 1.6%, respectively.

Now, here’s an open question: is a 6.5% improvement worth the extra computational cost and resources? Something to think about.

Solution 2: The “First Try” Inference Method

The second contribution of the article is a new inference method called "First Try."

What does this mean? Now that we have a granular database, we can use it to guide the model step by step in solving problems. Instead of tackling the entire problem in one go, the model uses specific steps from the database to find the solution.

This approach not only boosts accuracy but also makes the process faster. However, it raises new questions. For example, how effective is it with more complex problems? And how much larger does the database need to grow for broader applications?

Final Thoughts

As you can see, the article tackles a technical topic with practical implications. If AI models can improve their ability to "conquer" problems, they’ll become even more useful—not just for homework but also for advancing fields like science, engineering, and programming.

Now, what do you think? Are these improvements worth the investment? I’d love to hear your thoughts.
