Let's analyze the content of the provided image to solve the problems.

Problem 6

(a) Find the equations for the two hyperplanes $h_a$ and $h_b$.

Given that the points are classified into two classes (circles and crosses), we need to find the equations for the two hyperplanes that best separate these classes.

(b) Show the support vectors and the margins.

Identify the support vectors for each hyperplane and calculate the margins.

(c) Which of the two hyperplanes is better at separating the two classes based on the margin?

Compare the margins calculated in part (b) and determine which hyperplane is more effective.

Problem 7

(a) Write the equations of the cluster means $A_1$, $A_2$, and $A_3$ of the three clusters.

Identify the coordinates for each cluster mean and write their equations.

(b) Use the first reassignment of data points.

Reassign data points to the nearest cluster mean after the first iteration.

(c) Show only the final cluster centers.

Determine the final cluster centers after reassignment.

Problem 8

(a) Write the Euclidean distance between points and find the center point.

Use the Euclidean distance formula to find the distances between points and determine the center.

Detailed Analysis for Problem 6

Let's start with the detailed analysis of Problem 6.

(a) Finding the Equations of the Hyperplanes

Given the points (assuming coordinates are in the form (x, y)):

1. Identify the coordinates of the points classified as circles.
2. Identify the coordinates of the points classified as crosses.

For hyperplane $h_a$, assume the form $ax + by + c = 0$. Similarly, for $h_b$.

(b) Showing Support Vectors and Margins

1. Support vectors are the closest points to the hyperplane from each class.
2. Calculate the perpendicular distance from each support vector to the hyperplane.

(c) Comparing Margins

1. Margin is the distance between the hyperplane and the support vectors.
2. Compare the calculated margins to determine the better hyperplane.

Would you like me to proceed with detailed calculations for part (a) of Problem 6, or would you prefer assistance with a different part or problem?

Here are five potential questions you might consider:

1. How do we calculate the equation of a hyperplane given a set of points?
2. What method is used to find support vectors in a dataset?
3. How can we determine which hyperplane provides the best separation between two classes?
4. What is the significance of cluster means in data clustering?
5. How do we calculate the Euclidean distance between points in a plane?

Tip: When solving problems involving hyperplanes, always verify if the points satisfy the hyperplane equation to ensure accuracy.
