Python Coding Qn$($K$-$nearest neighbours algorithm$)$

K$-$Nearest neighbours algorithm

re ciodin

Is point:

DESCRIPTION

Load the features and $x_2$ are independent variables and Class is the response variable:

$x1$:$[7,7,3,1]$

$x2$:$[7,4,4,4]$

class: $[$ fall, Pfoll', 'Pass', 'Pass'$]$

Solution code

CODE

$1$ inport

$2$ import

$\frac{3}{x}$I $=np.$

$4,x_2=np.$

$5$ Class $=$

$6$ test$\_$int

$7$ distance

$8$ df $=$ pd

$9$ k$\_$neight

$10$ majority

$11$ print$($m$.$

The task is to implement the $K-$ nearest algorithm using

Numpy and Pandas

The new test query is $(3,4),$ Using $K=3,$ determine the class abel of the test instance.
