AI总结:

本文提出Lai loss,通过几何方式将梯度正则化融入损失函数,以控制模型平滑度与敏感度,并验证其能兼顾泛化性能、抗噪能力和稳定表现。

摘要:

在机器学习领域,传统的正则化方法倾向于直接向损失函数中添加正则化项。本文介绍了“Lai loss”,这是一种新颖的损失设计,通过直观的几何概念将正则化项(特别是梯度)整合到传统损失函数中。该设计利用损失本身对梯度进行惩罚,从而在确保最大准确率的同时实现对梯度的控制。借助这种损失,我们能够有效控制模型的平滑度和敏感度,可能带来提升模型泛化性能与增强其对特定特征抗噪能力的双重益处。此外,我们提出了一种训练方法,成功解决了实际应用中的挑战。我们使用来自Kaggle的公开数据集进行了初步实验,结果表明Lai loss的设计能够在保持模型性能稳定的同时控制模型的平滑度和敏感度。

英文摘要:

In the field of machine learning, traditional regularization methods tend to directly add regularization terms to the loss function. This paper introduces the "Lai loss", a novel loss design that integrates the regularization terms (specifically, gradients) into the traditional loss function through straightforward geometric concepts. This design penalizes the gradients with the loss itself, allowing for control of the gradients while ensuring maximum accuracy. With this loss, we can effectively control the model's smoothness and sensitivity, potentially offering the dual benefits of improving the model's generalization performance and enhancing its noise resistance on specific features. Additionally, we proposed a training method that successfully addresses the challenges in practical applications. We conducted preliminary experiments using publicly available datasets from Kaggle, demonstrating that the design of Lai loss can control the model's smoothness and sensitivity while maintaining stable model performance.
