摘要:
通过建立一个以系统和智能方式对胃癌癌前病变进行分类的模型，帮助医生找到敏感点和癌前息肉。在本文方法中，通过设计一种改进的ALexNet架构并使用数据增强、高斯噪声、L2权值衰减和ReLU等技术训练卷积神经网络模型，最后通过利用精度、损失值和混淆矩阵等性能指标对该模型的性能进行评估。在3 677张糜烂、息肉和溃疡等胃病图像上对所提出的模型进行测试，结果表明该模型的分类准确率达到89%。
Abstract:
Abstract: By building a model that can classify gastric precancerous lesions in a systematic and intelligent way, doctors can find sensitive points and precancerous polyps. An improved AlexNet architecture and techniques such as data enhancement, Gaussian noise, L2 weight decay and ReLU are used for training the convolutional neural network model and the performance of the proposed model is evaluated by analyzing its precision, loss value and confusion matrix. The proposed model is tested on 3 677 images of gastric diseases such as erosion, polyps and ulcers, and the results show that the classification accuracy of the proposed model reaches 89%.
