摘要

随着智能医疗的发展,人工智能在癌症诊断中的应用日益广泛。全幻灯片图像(wsi)在癌症诊断中发挥着重要作用,特别是在多实例学习(MIL)框架下,大规模医学图像数据处理可以显著提高诊断准确性。然而,传统的卷积神经网络(cnn)和Transformer模型在处理wsi方面仍然存在局限性,特别是在局部特征提取和全局上下文建模方面,导致较高的计算复杂度和内存消耗。为了解决这些问题,本文提出了一种结合Fusion Mamba模块、Agent Attention模块和ResNet50特征提取器的创新模型MamCancerX。MamCancerX通过跨层令牌融合和自关注机制优化了局部特征和全局信息的融合,提高了癌症分类任务的性能和效率。具体来说,Fusion Mamba模块提高了整体感知能力,而Agent Attention模块通过自我关注增强了模型对关键区域的关注。实验结果表明,MamCancerX在Camelyon16和BRACS数据集上表现出色,在准确率、AUC和F1分数等关键指标上优于现有方法,同时在内存消耗和计算效率方面也表现出显著优势。

Cancer diagnosis in smart healthcare: Optimization of the MamCancerX model’s multiple instance learning framework
With the development of smart healthcare, the application of artificial intelligence in cancer diagnosis has become increasingly widespread. Whole slide images (WSIs) play an important role in cancer diagnosis, especially within the multiple instance learning (MIL) framework, where large-scale medical image data processing can significantly improve diagnostic accuracy. However, traditional convolutional neural networks (CNNs) and Transformer models still have limitations in handling WSIs, particularly in local feature extraction and global context modeling, leading to high computational complexity and memory consumption. To address these issues, this paper proposes MamCancerX, an innovative model that combines the Fusion Mamba module, Agent Attention module, and ResNet50 feature extractor. MamCancerX optimizes the fusion of local features and global information through cross-layer token fusion and self-attention mechanisms, enhancing performance and efficiency in cancer classification tasks. Specifically, the Fusion Mamba module improves global perception, while the Agent Attention module enhances the model’s focus on key regions through self-attention. Experimental results show that MamCancerX excels on the Camelyon16 and BRACS datasets, outperforming existing methods in key metrics such as accuracy, AUC, and F1 score, while also demonstrating significant advantages in memory consumption and computational efficiency.
