Class Activity: Hierarchical clustering

For the following dataset:

Data Point	Feature
A	1
B	4
C	11
D	5
E	9

Perform the hierarchical clustering with single linkage.

Class Activity: K-means clustering

For the following dataset:

Data Point	Feature
A	1
B	4
C	11
D	5
E	9

Perform the K-means clustering with K=2. Assume that the initial center of clusters (i.e. randomly selected points in the space) are at 8 and 12.

Class Activity: KNN regression

We have the following dataset:

X	Y
1	3.2
0.5	1.8
0.25	1.7
-1	-0.8
-0.5	0.2
1.5	3.8

Use KNN with K=2 to predict the value of Y in the following test dataset. Use the Euclidean distance.

X	Y
-1.5	-1.8
2	4.8
0.75	2.7

Write down your answers in the text area.

Class Activity: Logistic Regression example

Using the following dataset, we want to design a logistic regression classifier:
