Python(multiple linear regression using Ordinary Least Square method) Question: Implement multiple linear regression using Ordinary Least Square method from scratch in Python. ****You are required to at least write your own the fit(), predict(), r2_score() method. Use the following dataset: titanic_train.csv, titanic_test.csv (both can be found online ,files are large so can't attach) Target: Predict whether or not the passenger survived the sinking of the Titanic. Remove unnecessary features if any.

Respond to two other classmates’ postings by critically reviewing your classmate's answer. The question: Differentiate between Big O, big Omega(Ω) and big theta, and which one you think is better to measure your algorithm efficiency, justify? 1st Answer: The better way to measure an algorithm is Big O because, in the worst-case scenario, we determine an algorithm's upper bound on execution time. We need to understand the scenario in which most operations are carried out. The worst scenario for a linear search is when an element x to be searched, is empty from the array. When x is empty, the search() method compares it with elements in arr[] one by one. Then that will show us the worst case of the algorithm which makes it easier to compare it to other classifications. 2nd Answer: The better way to measure an algorithm is Big O because we use big O notation is important when working with algorithms. We can develop efficient algorithms which can lead to less code(space complexity)…

Select true or false for the statements below. Explain your answers if you like to receive partial credit 7) Which of the following is true about Big-O notation?a. If we say an algorithm performs at O(n), you will get the same number ofoperations executed no matter how large the data set grows in sizeb. If algorithm 1 is O(n) and algorithm 2 is O(1), algorithm 1 is considered to besignificantly better than algorithm 2c. O(n log n) is significantly better than O(n)
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. Today the kindergarten has another gathering of n kids who should be situated during supper. The seats at the table are numbered from 1 to 4n. Two children can't sit on a similar seat. It is realized that two children who sit on seats with numbers an and b (a≠b) will enjoy if: gcd(a,b)=1 or, a partitions b or b separates a. gcd(a,b) — the greatest number x with the end goal that an is distinct by x and b is detachable by x. For instance, if n=3 and the children sit on seats with numbers 2, 3, 4, then, at that point, they will enjoy since 4 is isolated by 2 and gcd(2,3)=1. On the off chance that children sit on seats with numbers 4, 6, 10, they won't enjoy. The educator truly doesn't need the wreck at the table, so she needs to situate the children so there are no 2 of the child that can enjoy. All the more officially, she needs no pair of seats an and b that the children…

A picture is worth a thousand words’ goes the saying: How much information is contained in a picture if the picture size is 250 x 400 pixels, and each pixel may take one of 256 colors with equal probability? Assume there are 60,000 words in a dictionary, and the 1000 words may be selected randomly from this dictionary. How much information do these 1000 words convey? What is the flaw in the above comparison?

Hi Just got a question from an assignment given to me by Bradford University technical and professional skills,because we are doing it as a group and the question is this Problem 3: The n consecutive integers from 1 to n are written in a row. Design an algorithm that puts signs ‘+’ and ‘—’ in front of them so that the expression obtained is equal to 0 or, if the task is impossible to do, returns the message no solution. For additional information it’s this lem 8: There are n index cards in a row, with n distinct integers written on them (one number per card) so that the numbers are sorted in decreasing order. You are allowed to exchange any pair of cards that have exactly one card between them. Write an algorithm that sorts the cards in increasing order with the minimum number of exchanges.
