A single model is often used to classify text data, but the generalization effect of a single model on text data sets is poor. To improve the model classification accuracy, a method is proposed that is based on a deep neural network (DNN), recurrent neural network (RNN), and convolutional neural network (CNN) and integrates multiple models trained by a deep learning network architecture to obtain a strong text classifier. Additionally, to increase the flexibility and accuracy of the model, various optimizer algorithms are used to train data sets. Moreover, to reduce the interference in the classification results caused by stop words in the text data, data preprocessing and text feature vector representation are used before training the model to improve its classification accuracy. The final experimental results show that the proposed model fusion method can achieve not only improved classification accuracy but also good classification effects on a variety of data sets.
单一模型通常用于对文本数据进行分类,但单一模型对文本数据集的泛化效果较差。为了提高模型分类精度,提出了一种基于深度神经网络(DNN)、递归神经网络(RNN)和卷积神经网络(CNN)的方法,该方法集成了通过深度学习网络架构训练的多个模型,以获得强大的文本分类器。此外,为了提高模型的灵活性和准确性,使用了各种优化器算法来训练数据集。此外,为了减少文本数据中停用词对分类结果的干扰,在训练模型之前使用数据预处理和文本特征向量表示来提高其分类精度。最终的实验结果表明,所提出的模型融合方法不仅可以提高分类精度,而且可以在各种数据集上获得良好的分类效果。
