摘要:

近年来,结直肠癌已成为危害人类健康的重要疾病之一。深度学习方法对于结直肠组织病理学图像的分类越来越重要。然而,现有的方法更多地关注使用计算机的端到端自动分类,而不是人机交互。在本文中,我们提出了一个IL-MCAM框架。它是基于注意力机制和互动学习。建议的IL-MCAM框架包括两个阶段:自动学习(AL)和交互式学习(IL)。在人工智能阶段,使用包含三个不同注意力机制通道和卷积神经网络的多通道注意力机制模型来提取用于分类的多通道特征。在IL阶段,所提出的IL-MCAM框架不断添加错误分类的图像的训练集在一个交互式的方法,这提高了MCAM模型的分类能力。我们在我们的数据集上进行了比较实验,并在HE-NCT-CRC-100 K数据集上进行了扩展实验,以验证所提出的IL-MCAM框架的性能,分别达到98.98%和99.77%的分类准确率。此外,我们还进行了烧蚀实验和可重复性实验,以验证这三个通道的能力和可重复性。实验结果表明,所提出的IL-MCAM框架具有良好的性能在大肠组织病理图像分类任务。

英文摘要:

In recent years, colorectal cancer has become one of the most significant diseases that endanger human health. Deep learning methods are increasingly important for the classification of colorectal histopathology images. However, existing approaches focus more on end-to-end automatic classification using computers rather than human-computer interaction. In this paper, we propose an IL-MCAM framework. It is based on attention mechanisms and interactive learning. The proposed IL-MCAM framework includes two stages: automatic learning (AL) and interactivity learning (IL). In the AL stage, a multi-channel attention mechanism model containing three different attention mechanism channels and convolutional neural networks is used to extract multi-channel features for classification. In the IL stage, the proposed IL-MCAM framework continuously adds misclassified images to the training set in an interactive approach, which improves the classification ability of the MCAM model. We carried out a comparison experiment on our dataset and an extended experiment on the HE-NCT-CRC-100K dataset to verify the performance of the proposed IL-MCAM framework, achieving classification accuracies of 98.98% and 99.77%, respectively. In addition, we conducted an ablation experiment and an interchangeability experiment to verify the ability and interchangeability of the three channels. The experimental results show that the proposed IL-MCAM framework has excellent performance in the colorectal histopathological image classification tasks.
