摘要:

乳腺癌分类仍然是一项具有挑战性的任务,由于类间的模糊性和类内的变异性。现有的基于深度学习的方法试图通过利用复杂的非线性投影来应对这一挑战。然而,这些方法通常从整个图像中提取全局特征,忽略了微妙的细节信息在提取判别特征时可能是至关重要的。在这项研究中,我们提出了一种新的方法命名为注意力模型增强网络(AMEN),这是制定在一个多分支的方式与像素明智的注意力模型和分类子模块。具体地说,AMEN中的特征学习部分可以生成逐像素的注意力图,而分类子模块用于分类样本。为了更好地关注图像中的细微细节信息,利用前一分支生成的像素级注意力图对样本图像进行了增强。此外,采用提升策略融合不同分支的分类结果,以获得更好的性能。在三个基准数据集上进行的实验证明了该方法在各种场景下的优越性。

英文摘要:

Breast cancer classification remains a challenging task due to inter-class ambiguity and intra-class variability. Existing deep learning-based methods try to confront this challenge by utilizing complex nonlinear projections. However, these methods typically extract global features from entire images, neglecting the fact that the subtle detail information can be crucial in extracting discriminative features. In this study, we propose a novel method named Attention Model Enhanced Network (AMEN), which is formulated in a multi-branch fashion with pixel-wised attention model and classification submodular. Specifically, the feature learning part in AMEN can generate pixel-wised attention map, while the classification submodular are utilized to classify the samples. To focus more on subtle detail information, the sample image is enhanced by the pixel-wised attention map generated from former branch. Furthermore, boosting strategy are adopted to fuse classification results from different branches for better performance. Experiments conducted on three benchmark datasets demonstrate the superiority of the proposed method under various scenarios.
