This paper proposes a face novel recognition method based on Weighted PCA, which combined weighted features with PCA. At first, we calculate the weighted subspace for each class by minimizing the weighted reconstruction error.
将特征加权和主元分析相结合,提出了一种新的加权主元分析方法;这种方法先根据加权重建误差最小化,计算出各类训练样本的加权子空间,然后计算测试样本点到各加权子空间的距离,并根据该距离进行分类识别。

Based on feature processing and model compensation, a weighted features compensation transformation method based on GMM for robust speaker verification was proposed.
从特征值处理和模型补偿两方面考虑，提出了基于高斯混合模型的加权特征补偿变换的抗噪声方法。
At the start, the sales and customer stakeholders might be weighted higher than the operations stakeholder so that new features are higher priority on the backlog.
一开始，销售人员和客户干系人的权重值会高于运营人员，这样新功能在待办事项列表中会有较高的优先级。
The texture features such as direction and contrast of the image can be obtained from weighted projection statistics of primitive feature, which are more matched with human vision.
然后通过对基元特征进行加权投影统计，得到图像的方向性、对比度等纹理特征，这些特征可以更好的适应人类视觉特性。
