论文摘要
通过分类(RVC)回归是一种常见方法,用于深度学习中的回归问题,其中目标变量属于一组连续值。通过将目标离散为一组非重叠类别,已经表明,与使用标准回归方法相比,分类器可以提高神经网络精度。但是,尚不清楚如何选择一组离散类别以及如何影响整体解决方案。在这项工作中,我们建议与单个表示相比,同时使用几种离散数据表示可以改善神经网络学习。我们的方法是端到端的,可以作为对传统学习方法(例如深度神经网络)的简单扩展而添加。我们在三个具有挑战性的任务上测试了我们的方法,并表明我们的方法与基线RVC方法相比,在保持相似的模型复杂性的同时减少了预测误差。
Regression via classification (RvC) is a common method used for regression problems in deep learning, where the target variable belongs to a set of continuous values. By discretizing the target into a set of non-overlapping classes, it has been shown that training a classifier can improve neural network accuracy compared to using a standard regression approach. However, it is not clear how the set of discrete classes should be chosen and how it affects the overall solution. In this work, we propose that using several discrete data representations simultaneously can improve neural network learning compared to a single representation. Our approach is end-to-end differentiable and can be added as a simple extension to conventional learning methods, such as deep neural networks. We test our method on three challenging tasks and show that our method reduces the prediction error compared to a baseline RvC approach while maintaining a similar model complexity.
