There is a bike rent store. Given excel file gives number of rentals based on given features. There are 3 features in the dataset and 732 samples. The features are temperature, humidity, and windspeed. In not cold and not hot temperatures, low humidity, and low windspeed, it is expected to have more bike rentals.
Requirements:
In this assignment you will develop a linear regression model with multiple features. You can use scikit-learn API. Make sure to split your data in training and test sets (randomly; in order not to have bias). Here is a scikit-learn example on how to split your data in training and test sets:
from sklearn.model_selection import train_test_split
x_train, x_test, y_train, y_test = train_test_split(x, y, random_state = 1234)
Visualize your data using scatter plot from matplotlib such as
bikerentals.plot(kind = 'scatter', x = 'temperature', y = 'rentals')
Visualize temperature in x axis, and rentals on y axis
Visualize humidity in x axis, and rentals on y axis
Visualize windspeed in x axis and rentals in y axis.
From these visualizations, explain if you see any correlation between individual features and rentals. Clearly explain for each feature.
After training your linear regression model on training dataset, test it on test dataset.
Report your results and accuracy of your results
From results you obtained from scikit linear regression model, write your final hypothesis function by obtaining coefficients (parameters; Thetas mentioned in class). Note: In scikit-learn your model’s intercept_ variable is Theta0, coef_ variable is a list of other Theta parameters (coefficients) e.g. Theta 1, Theta 2, …etc. Based on these obtained values clearly write your Hypothesis function.

Answer:

Answer:

False

Explanation:

HTML is a platform independent language.

Answer:

B

Explanation:

a. Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions.

b. The expected number of inversions, E[X],  E[X] = 1/4n(n-1).

c. In the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

(a) Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions. To understand why this is true, let's refer to the pseudocode for Insertion-Sort:

InsertionSort(A):

  for i from 1 to length[A] do

     key = A[i]

     j = i - 1

     while j >= 0 and A[j] > key do

        A[j + 1] = A[j]

        j = j - 1

     A[j + 1] = key

b. The expected number of inversions, E[X], can be calculated as follows:

E[X] = Σ(i,j) E[I(i, j)]

= Σ(i,j) Pr((i, j) is an inversion)

= Σ(i,j) 1/2

= (n(n-1)/2) * 1/2

= n(n-1)/4

Hence, E[X] = 1/4n(n-1).

(c) Using Proposition 2 and the result from part (b), we can determine the average case time complexity of Insertion-Sort. The average case time complexity is given by O(n + E[X]).

Substituting the value of E[X] from part (b):

Average case time complexity = O(n + 1/4n(n-1))

Simplifying further:

Average case time complexity = O(n + 1/4n^2 - 1/4n)

Since 1/4n² dominates the other term, we can approximate the average case time complexity as:

Average case time complexity ≈ O(1/4n²)

Therefore, in the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

import java.util.Scanner;

public class MultiplicationTablePractice {

   public static void main(String[] args) {

       var scanner = new Scanner(System.in);

       var quit = false;

       while (!quit) {

           var randomNumber1 = (int) (Math.random() * 12) + 1;

           var randomNumber2 = (int) (Math.random() * 12) + 1;

           System.out.println(randomNumber1 + " * " + randomNumber2 + " = ?");

           var answer = scanner.nextInt();

           if (answer == randomNumber1 * randomNumber2) {

               System.out.println("Correct!");

           } else {

               System.out.println("Wrong!");

           }

           System.out.println("Quit? (y/n)");

           var quitInput = scanner.next();

           if (quitInput.equals("y") ||

               quitInput.equals("Y")) {

               quit = true;

           }

       }

       scanner.close();

   }

}

Explanation:

First, we create a new scanner object, based on the System.in stream. Then we create a varaible called quit which we set to false which we then use as the condition for the while loop.

Inside the scope of the while loop, we create two random numbers based off of Math.random(). The formula we use is (int) (Math.random() * 12) + 1; With these new variables, we print:

randomNumber1 + " * " + randomNumber2 + " = ? "

After this is printed, we scan the user input as an int.  We check the input answer against the actual answer to check if it's correct or not. If it is correct, we print "Correct!" otherwise we print "Wrong!".

Once all of this is handled, we ask the user if they want to quit or not. If the input is "y" or "Y" the while loop terminates, and the scanner closes. Otherwise, the while loop will continue, and restart the process.

The matrix A=[-4 2 1;2 -4 1;1 2 -4] can be created by using the following code in Matlab/Octave:

A = -4*eye(3) + 2*(eye(3,3) - eye(3)) + (eye(3,3) - 2*eye(3))

Here, eye(3) creates an identity matrix of size 3x3 with ones on the diagonal and zeros elsewhere.

eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.

eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.

The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.

You can also create the matrix A by using following code:

A = [-4 2 1; 2 -4 1; 1 2 -4]

It is not necessary to create the matrix A using only ones and zeroes but this is one of the way to create this matrix.
