Time Series Estimation Problem We will estimate value of Y for x = 6.

X Y distance K-NN value(when K = 2) 1 5 5 2 9 4 3 15 3 4 20 2 20 7 30 1 30 6  ?

1. Decide K. In this example let K = 2.

2. Find distance from the current X value

3. Decide K-NN value => 20 & 30

4. Estimate Y value by taking K mean values of X

  Y = (20+30)/2 = 25

Answer: Estimated(Predicted) Y = 25
