They describe characteristics of the cell nuclei present in the image. The target feature records the prognosis (benign (1) or malignant (2)). [Original data available here](ftp://ftp.cs.wisc.edu/math-prog/cpo-dataset/machine-learn/cancer/) \n\nCurrent dataset was adapted to ARFF format from the UCI version. Sample code ID's were removed.  \n\n! Note that there is also a related Breast Cancer Wisconsin (Original) Data Set with a different set of features, better known as [breast-w](https://www.openml.org/d/15).\n\n\n### Feature description  \n\nTen real-valued features are computed for each of 3 cell nuclei, yielding a total of 30 descriptive features. See the papers below for more details on how they were computed. The 10 features (in order) are:  \n\na) radius (mean of distances from center to points on the perimeter)  \nb) texture (standard deviation of gray-scale values)  \nc) perimeter  \nd) area  \ne) smoothness (local variation in radius lengths)  \nf) compactness (perimeter^2 / area - 1.0)  \ng) concavity (severity of concave portions of the contour)  \nh) concave points (number of concave portions of the contour)  \ni) symmetry  \nj) fractal dimension (\"coastline approximation\" - 1)  \n\n### Relevant Papers   \n\nW.N.
