编码器组 meaning in English

encoder group

The other one is the synthetical local nonlinear pca neural network recognition model constructed by combining the nonlinear generalization of pca and sub - space pattern recognition technology . we use the two recognition systems in handwritten digitals and characters recognition and obtain some satisfactory results . compared with some traditional classifiers , our systems have better recognition performances
而基于非线性pca的神经网络识别模型对传统的线性pca进行了推广，并利用了子空间的模式识别方法，针对每个字符类使用神经网络建立多个模板，然后利用pca神经网络和聚类算法构造自动编码器组对模式类进行重构，避免了特征提取的复杂性和信息的丢失，提高了系统的识别性能和运算效率。
