Step-dpo: step-wise preference optimization for long-chain reasoning of llms.
26 Jun 2024 · Xin Lai , Zhuotao Tian , Yukang Chen , Senqiao Yang , Xiangru Peng , Jiaya Jia · Edit social preview
Mathematical reasoning presents a significant challenge for Large Language Models (LLMs) due to the extensive and precise chain of reasoning required for accuracy. Ensuring the correctness of each reasoning step is critical. To address this, we aim to enhance the robustness and factuality of LLMs by learning from human feedback. However, Direct Preference Optimization (DPO) has shown limited benefits for long-chain mathematical reasoning, as models employing DPO struggle to identify detailed errors in incorrect answers. This limitation stems from a lack of fine-grained process supervision. We propose a simple, effective, and data-efficient method called Step-DPO, which treats individual reasoning steps as units for preference optimization rather than evaluating answers holistically. Additionally, we have developed a data construction pipeline for Step-DPO, enabling the creation of a high-quality dataset containing 10K step-wise preference pairs. We also observe that in DPO, self-generated data is more effective than data generated by humans or GPT-4, due to the latter's out-of-distribution nature. Our findings demonstrate that as few as 10K preference data pairs and fewer than 500 Step-DPO training steps can yield a nearly 3% gain in accuracy on MATH for models with over 70B parameters. Notably, Step-DPO, when applied to Qwen2-72B-Instruct, achieves scores of 70.8% and 94.0% on the test sets of MATH and GSM8K, respectively, surpassing a series of closed-source models, including GPT-4-1106, Claude-3-Opus, and Gemini-1.5-Pro. Our code, data, and models are available at https://github.com/dvlab-research/Step-DPO.

The implementation of a solution requires planning and execution. It's often iterative, where the focus should be on short implementation cycles with testing and feedback, not trying to get it "perfect" the first time. Input: decision; planning; hard work. Output: resolution to the problem. 5.
4. Implement the Solution. At this stage of problem solving, be prepared for feedback, and plan for this. When you roll out the solution, request feedback on the success of the change made. 5. Review, Iterate, and Improve. Making a change shouldn't be a one time action.
In general, effective problem-solving strategies include the following steps: Define the problem. Come up with alternative solutions. Decide on a solution. Implement the solution. Problem-solving ...
The problem solving process typically includes: Pinpointing what's broken by gathering data and consulting with team members. Figuring out why it's not working by mapping out and troubleshooting the problem. Deciding on the most effective way to fix it by brainstorming and then implementing a solution. While skills like active listening ...
The problem-solving process typically includes the following steps: Identify the issue: Recognize the problem that needs to be solved. Analyze the situation: Examine the issue in depth, gather all relevant information, and consider any limitations or constraints that may be present. Generate potential solutions: Brainstorm a list of possible ...
Problem-solving is a mental process that involves discovering, analyzing, and solving problems. The ultimate goal of problem-solving is to overcome obstacles and find a solution that best resolves the issue. The best strategy for solving a problem depends largely on the unique situation. In some cases, people are better off learning everything ...
Making a decision to alter the way your team works may also be a problem. Launching new products, technological upgrades, customer feedback collection exercises—all of these are also "problems" that need to be "solved". Here are the steps of a problem-solving process: 1. Defining the Problem. The first step in the process is often ...
Perhaps you've got a problem you need to tackle. Or maybe you want to be prepared the next time one arises. Either way, it's a good idea to get familiar with the five steps of problem-solving. Use this step-by-step problem-solving method with the strategies in the following section to find possible solutions to your problem. 1. Identify the ...
Consider the following steps to build your own problem-solving process: 1. Reflect on your past problems and solutions. One way to begin designing your problem-solving process is by reflecting on your past problems and how you solved them. Think about the process you went through when you solved past problems, and consider how you could apply ...
Step 1 - Define the Problem. The definition of the problem is the first step in effective problem solving. This may appear to be a simple task, but it is actually quite difficult. This is because problems are frequently complex and multi-layered, making it easy to confuse symptoms with the underlying cause.
Finding a suitable solution for issues can be accomplished by following the basic four-step problem-solving process and methodology outlined below. Step. Characteristics. 1. Define the problem. Differentiate fact from opinion. Specify underlying causes. Consult each faction involved for information.
When it comes to problem-solving there are seven key steps that you should follow: define the problem, disaggregate, prioritize problem branches, create an analysis plan, conduct analysis, synthesis, and communication. 1. Define the problem. Problem-solving begins with a clear understanding of the issue at hand.
Step 1: Identify. Identifying the problem may be simple, or it could be a detailed cognitive process that breaks the issue into manageable components. Either way, what you do during the identify step of the problem-solving process sets the stage for the next steps in problem solving.
Several mental processes are at work during problem-solving. Among them are: Perceptually recognizing the problem. Representing the problem in memory. Considering relevant information that applies to the problem. Identifying different aspects of the problem. Labeling and describing the problem.
In this article, we'll provide practical steps that can help you effectively solve problems at your workplace. Step 1: Define the Problem. The first step in effective problem solving is to define the problem clearly. Take the time to analyze the issue and gather as much information as possible. It's crucial to identify the cause of the ...
Problem-solving can also empower a workforce and make its members more confident. If an entire organization can problem-solve efficiently, they can spend their time more wisely. 5 Steps to Better Problem-Solving Step 1: Identify the Problem.

Make a simple plan to solve your problem, avoiding unnecessary detail. You can use an action tracker, which can be a spreadsheet that breaks down who does what and when. In the first column, put all the actions that make up your problem-solving steps. In the second column, note who is responsible for each action and when it should be done.

Although problem-solving is something everyone does on a daily basis, many people lack confidence in their ability. Here we look at the basic problem-solving process to help keep you on the right track.
When we do problem definition well in classic problem solving, we are demonstrating the kind of empathy, at the very beginning of our problem, that design thinking asks us to approach. When we ideate—and that's very similar to the disaggregation, prioritization, and work-planning steps—we do precisely the same thing, and often we use ...
The Problem-Solving Routine. At Two Rivers, we use a fairly simple routine for problem solving that has five basic steps. The power of this structure is that it becomes a routine that students are able to use regularly across multiple contexts. The first three steps are implemented before problem-solving. Students use one step during problem ...
