arXiv:2605.30135v1 Announce Type: new Abstract: Various algorithms have been proposed to address the challenges posed by class-imbalanced learning from real-world data with long-tailed distributions. While these algorithms reduce prediction bias through rebalancing techniques, they often introduce increased prediction variance as a trade-off. Several multi-expert learning algorithms aim to address this variance but involve complex procedures. We propose a new multi-expert learning algorithm, called the dual-axis multi-expert learning (DAMEL), which reduces both bias and variance of predictions
The paper addresses ongoing challenges in class-imbalanced learning, a prevalent issue in real-world AI applications, building on recent advancements in multi-expert learning. This is happening now as AI models are deployed in increasingly complex, real-world scenarios where data distribution is rarely uniform.
Improving how AI models handle imbalanced datasets is crucial for their reliability and fairness in critical applications, reducing errors that can have significant real-world consequences. This advancement directly impacts the trustworthiness and effectiveness of AI systems across various domains.
The proposed DAMEL algorithm offers a more efficient and less complex method to mitigate both bias and variance in predictions from imbalanced data, potentially leading to more robust and accurate AI systems. This could simplify the development and deployment of certain types of AI models.

- · Machine learning practitioners
- · Industries relying on AI with imbalanced data (e.g., healthcare, finance)
- · AI ethics and fairness initiatives
- · Developers of overly complex or less effective multi-expert learning algorithms
AI models across various applications, from medical diagnosis to fraud detection, become more accurate and reliable when faced with uneven data distributions.
This improved reliability could accelerate the adoption of AI in sensitive sectors where data imbalance is a known barrier to trust and performance.
More robust AI systems, by reducing prediction errors, might lead to fairer outcomes in areas like credit scoring or resource allocation, ultimately influencing social equity debates around AI.
