Breast Cancer Wisconsin Dataset - Classification

Description :

This dataset provides information about the features which are computed from a digitized image of a fine needle aspirate (FNA) of a breast mass. These features describe characteristics of the cell nuclei present in the image. 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].

Recommended Model :

Algorithms to be used: random forest, svm, logistic regression etc

Recommended Project :

Prediction of developing Breast Cancer

Overview of data

Detailed overview of dataset:

- Rows = 569

- Columns= 31

1) ID number 2) Diagnosis (M = malignant, B = benign)

Ten real-valued features are computed for each cell nucleus: a) radius (mean of distances from center to points on the perimeter) b) texture (standard deviation of gray-scale values) c) perimeter d) area e) smoothness (local variation in radius lengths) f) compactness (perimeter^2 / area - 1.0) g) concavity (severity of concave portions of the contour) h) concave points (number of concave portions of the contour) i) symmetry j) fractal dimension ("coastline approximation" - 1)
