Breast cancer

This is one of three domains provided by the Oncology Institute that has repeatedly appeared in the machine learning literature. (See also lymphography and primary-tumor.) This data set includes 201 instances of one class and 85 instances of another class. The instances are described by 9 attributes, some of which are linear and some are nominal. **Source** [Breast Cancer Data Set](http://archive.ics.uci.edu/ml/datasets/Breast+Cancer) at [UCI Repository](http://archive.ics.uci.edu/ml/index.html)本数据集为肿瘤学研究所（Oncology Institute）提供的三类数据集之一，曾多次出现于机器学习学术文献中，另可参考淋巴造影（lymphography）与原发肿瘤（primary-tumor）数据集。 本数据集包含两类样本：一类包含201个实例，另一类包含85个实例。所有样本均由9个属性进行描述，其中部分属性为线性属性，部分为名义（nominal）属性。 **数据集来源** [乳腺癌（Breast Cancer）数据集](http://archive.ics.uci.edu/ml/datasets/Breast+Cancer)，收录于[UCI机器学习存储库（UCI Repository）](http://archive.ics.uci.edu/ml/index.html)
