Part B

1.

K=7

k=17

The robot from images can be seen to turn its arm from shoulder and elbow and also move vertically from 1 hence a dimensionality of 3 is expected which is what is observed for a higher number of nearest neighbour. The value of k affects the analysis.The error is more if too small value of k is taken as can be seen in this case where it shows a dimensionality of 2

2.

K=7

k=27

The motion of the two rods requires 4 angles to be specified for describing its complete location and hence a dimensionality of 4 is observed. The choice of k affects the analysis considerably. Larger errors are observed for very small values of k.
