this Jupyter Notebook we will focus on $KNN-Algorithm$. KNN is a data classification algorithm that attempts to determine what group a data point is in by looking at the data points around it.\n",
    "\n",
    "An algorithm, looking at one point on a grid, trying to determine if a point is in group A or B, looks at the states of the points that are near it. The range is arbitrarily determined, but the point is to take a sample of the data. If the majority of the points are in group A, then it is likely that the data point in question will be A rather than B, and vice versa.\n",
