红酒分类问题某研究获取了若干红酒的类别数据，存放于 wine数据.txt 中。
每个样本的第一个属性是类别（1或2或3），其余按顺序均有如下13个属性
1) Alcohol 2) Malic acid 3) Ash 4) Alcalinity of ash 5) Magnesium 6) Total phenols 7) Flavanoids 8) Nonflavanoid phenols 9) Proanthocyanins 10)Color intensity 11)Hue 12)OD280/OD315 of diluted wines 13)Proline 要求：自行选出训练样本和测试样本，如有必要可先对数据做预处理（如离散化、降维等）
说明：由于sklearn自带的红酒数据集（wine）与提供的 wine数据.txt 数据内容一样，所以本实验直接导入相应包以及红酒数据集。

四、结果分析
根据上面的实验结果截图，可得：
①原始数据下，KNN算法分类准确率为69.23%，SVM算法分类准确率为100%，人工神经网络算法分类准确率为97.44%。
②标准化后数据下，KNN算法分类准确率为94.87%，SVM算法分类准确率为98.72%，人工神经网络算法分类准确率为100%。
③PCA降维后数据下，KNN算法分类准确率为97.44%，SVM算法分类准确率为97.44%，人工神经网络算法分类准确率为94.87%。
可见，每种算法在不同的数据处理下效果也大不相同。SVM算法在不对数据进行预处理的情况下就能够达到100%的分类准确率，在数据进行标准化和PCA降维后，准确率反而下降了，而KNN和神经网络算法则是在数据预处理之后准确率有所提升，KNN算法提升效果尤为明显，原始数据下的准确率只有69.23%，而PCA降维后提高到了97.44%。因此，并非每种分析算法都适应全部的数据集，不一样数据集其特征不一样，最佳分析的算也会不一样，所以在进行数据分析时，一般会对比多种分析算法，再优化本身的实验和模型。
