In this project, we aim to predict whether a tumor is benign or malignant. we implemented KNN on Python. The data contains the following columns: BI_RADS_assessment: Definitely benign(1) to Highly suggestive of malignancy (5) Age: patient’s age in years Shape: mass shape: round=1 oval=2 lobular=3 irregular=4 (nominal) Margin: mass margin: circumscribed=1 microlobulated=2 obscured=3 ill-defined=4 spiculated=5 (nominal) Density: mass density high=1 iso=2 low=3 fat-containing=4 (ordinal) Severity: Predictor Class: benign=0 or malignant=1 . let’s get our environment …
