【机器学习】IrisDataSet（鸢尾属植物数据集）注：数据是机器学习模型的原材料，当下机器学习的热潮离不开⼤数据的⽀撑。在机器学习领域，有⼤量的公开数据集可以使⽤，从⼏百个样本到⼏⼗万个样本的数据集都有。有些数据集被⽤来教学，有些被当做机器学习模型性能测试的标准（例如ImageNet图⽚数据集...
The Iris dataset was used in R.A. Fisher's classic 1936 paper, The Use of Multiple Measurements in Taxonomic Problems, and can also be found on the UCI Machine Learning Repository. It includes three iris species with 50 samples each as well as some properties about each flower. One flower...
