数据收集经常导致缺少值或变量的记录。本研究比较了3种不同的数据归算模型，并用精确度衡量它们的优点。采用自编码器神经网络、主成分和支持向量回归进行预测，并结合遗传算法对缺失变量进行归算。PCA的使用提高了自动编码器网络的整体性能，而支持向量回归的使用显示了未来研究的潜力。对部分变量的归算精度可达97.4%。

英文摘要：
  Data collection often results in records that have missing values or variables. This investigation compares 3 different data imputation models and identifies their merits by using accuracy measures. Autoencoder Neural Networks, Principal components and Support Vector regression are used for prediction and combined with a genetic algorithm to then impute missing variables. The use of PCA improves the overall performance of the autoencoder network while the use of support vector regression shows promising potential for future investigation. Accuracies of up to 97.4 % on imputation of some of the variables were achieved.
