c++ 模式识别。这里主要是做了人脸识别的实验-c pattern recognition. Here is a face recognition experiments

The Principal component analysis, is a standard technique used for data reduction in statistical pattern recognition and signal processing A common problem in statistical pattern recognition is feature selection or feature extraction. Feature selec

这是一个小而有效的程序来执行的K -近邻搜索算法，此算法利用JIT 理论加速循环，比向量化有效解决了大量数据的精度问题。甚至比kd-tree效果要佳。 K-nearest neighbor search已经广泛应用在科学与工程上，比如模式识别，数据挖掘和信号处理。 -This is a small and effective procedures to implement the K- nearest neighbor search algorithm, this algorithm J
