To address the diverse needs of enterprise users and the cold-start issue of recommendation system, this paper proposes a quality-service demand classification method-, based on cross-entropy loss and one-dimensional convolutional neural network (1D-CNN) with the comprehensive enterprise quality portrait labels. The main idea of 1D-CNN-CrossEntorpyLoss is to use cross-entropy to minimize the loss of 1D-CNN model and enhance the performance of the enterprise quality-service demand classification. The transaction data of the enterprise quality-service platform are selected as the data source. Finally, the performance of 1D-CNN-CrossEntorpyLoss is compared with XGBoost, SVM, and logistic regression models. From the experimental results, it can be found that 1D-CNN-CrossEntorpyLoss has the best classification results with an accuracy of 72.44%. In addition, compared to the results without the enterprise-quality portrait, the enterprise-quality portrait improves the accuracy and recall of 1D-CNN-CrossEntorpyLoss model. It is also verified that the enterprise-quality portrait can further improve the classification ability of enterprise quality-service demand, and 1D-CNN-CrossEntorpyLoss is better than other classification methods, which can improve the precision service of the comprehensive quality service platform for MSMEs.
为满足企业用户的多样化需求以及解决推荐系统的冷启动问题,本文提出了一种基于交叉熵损失和一维卷积神经网络(1D-CNN)的质量服务需求分类方法,并结合全面的企业质量画像标签。1D-CNN-交叉熵损失的主要思想是利用交叉熵来最小化1D-CNN模型的损失,并提高企业质量服务需求分类的性能。选取企业质量服务平台的交易数据作为数据源。最后,将1D-CNN-交叉熵损失的性能与XGBoost、支持向量机(SVM)和逻辑回归模型进行比较。从实验结果可以发现,1D-CNN-交叉熵损失具有最佳的分类结果,准确率为72.44%。此外,与没有企业质量画像的结果相比,企业质量画像提高了1D-CNN-交叉熵损失模型的准确率和召回率。还验证了企业质量画像可以进一步提高企业质量服务需求的分类能力,并且1D-CNN-交叉熵损失优于其他分类方法,这可以提高综合质量服务平台对中小企业的精准服务。
