摘要:
基础概率模型是现代深度学习的基础,主要通过定义网络的最终激活层,并允许将网络输出通过概率视角进行解释。通过增加这些最终激活层的复杂度,以纳入空间正则化等特征,可使这些模型在无需显著增加数据量的情况下提升性能。然而,挑战在于确保这些更复杂的概率图模型能与深度学习协同良好适配,即保证它们收敛且具有有意义的导数。本文的目标是展示两种具有可证收敛性质的算法,以实现图像和信号分类模型的此类正则化。通过严格的数学分析和计算机模拟实验,我们可展示这两种解决方案类型之间的性能差异。
英文摘要:
Basic probabilistic models form the basis of modern deep learning largely by defining the final activation layer of a network and allowing the networks outputs to be interpreted through a probabilistic lens. By increasing the complexity of these final activation layers to include features such as spatial regularisation, allow for these models to improve in performance without requiring significantly more data. The challenge however is to ensure that these more complex probabilistic graphical models adapt well to being used in tandem with deep learning, that is, ensuring they converge and have meaningful derivatives. The goal of this paper is to show two algorithms with provable convergence properties to allow this type of regularisation for image and signal classification models. Through both rigorous mathematical analysis and in silico experiments, we can show the differing performance between these solution types.
