Introduction
Multimodal reasoning is essential for applications like intelligent agents and robotics. Self-evolving training can improve reasoning abilities without needing external annotated data, but its application in multimodal contexts is limited. This paper identifies key factors for effective self-evolving training in multimodal reasoning.
Training Methods
The paper introduces Continuous Self-Evolving, a new training variant that bridges iterative training and online reinforcement learning. It discusses the impact of different training methods and the importance of iteration intervals.
Overview of Self-Evolving Training for Multimodal Reasoning
Self-evolving training is framed as a reinforcement learning problem, where the goal is to maximize a reward function. The paper discusses the challenges of optimizing this objective and presents a decoupled approach to improve stability and scalability.

Diving into Self-Evolving Design Components
The paper examines three key components of self-evolving training, providing a comprehensive analysis to identify best practices for multimodal self-evolution.
General Setup
The study is based on MiniCPM-V-2.5 and validated on additional models. It utilizes the MathV360K dataset for training and evaluation, with specific training settings and a self-warmup stage to enhance generation abilities.
Figures Explained
The paper’s visual material highlights the workflow and the main system components.
- Figure 1 :: Figure 1: Overview of our self-evolving training framework for multimodal reasoning. We investigate the three essential design components of it, namely Training method (T ), Reward model (R), and Prompt variation (P). Orthogonal to the static factors, the Dynamics of self-evoloution is also monitered, and provides control signals to the training process.
- Figure 2: What makes PRM work for self-evolving training? To pursue deeper insights into the role of PRM in self-evolving training, we conduct an analysis presented in Figure2. Based on the results from §3.3, we explore PRM’s impact from two key perspectives: (1) Can PRM help the model to select out correct responses among multiple rollouts? (2) How different are the Top 2 and the rest correct solutions re-ranked by reward scores? We use the first checkpoint.
- Figure 2 :: Figure 2: (a): Accuracy on the val. set of greedy decoding and three selection strategy across different numbers of rollouts; (b): Average relativity score annotated by GPT4-o of Top 2 and the rest responses re-ranked by rewards, we only calculate on correct ones.
- Figure 3 :: Figure 3: Opposite trend of Greedy Accuracy and Pass@K. self-evolving training can harm the process, potentially causing a deviation in the policy model’s distribution.
- Figure 4 :: Figure 4: (a): decreases for all different temperatures; (b): The Reward-Pass@2 saturates quickly. All metrics are calculated on validation set.with other metrics.
