## Breast Cancer Wisconsin Diagnostic Dataset
|
5 |

|
6 |
+
Following description was retrieved from [breast cancer dataset on UCI machine learning repository](https://archive.ics.uci.edu/ml/datasets/breast+cancer+wisconsin+(diagnostic)).

Features are computed from a digitized image of a fine needle aspirate (FNA) of a breast mass. They describe characteristics of the cell nuclei present in the image. A few of the images can be found at [here](https://pages.cs.wisc.edu/~street/images/).

Separating plane described above was obtained using Multisurface Method-Tree (MSM-T), a classification method which uses linear programming to construct a decision tree. Relevant features were selected using an exhaustive search in the space of 1-4 features and 1-3 separating planes.
|

|
12 |
+
The actual linear program used to obtain the separating plane in the 3-dimensional space is that described in: [K. P. Bennett and O. L. Mangasarian: "Robust Linear Programming Discrimination of Two Linearly Inseparable Sets", Optimization Methods and Software 1, 1992, 23-34].

Ten real-valued features are computed for each cell nucleus:
|
20 |

|
21 |
+
- radius (mean of distances from center to points on the perimeter)
|
22 |
+
- texture (standard deviation of gray-scale values)
|
23 |
+
- perimeter
|
24 |
+
- area
|
25 |
+
- smoothness (local variation in radius lengths)
|
26 |
+
- compactness (perimeter^2 / area - 1.0)
|
27 |

- concavity (severity of concave portions of the contour)
|
28 |

- fractal dimension ("coastline approximation" - 1)
