Suppose Uber was considering a new algorithm to recommend ride destinations in the app. Which type of research strategy should they use (A/B Test, Switchback, Synthetic Control)

Answers

Answer 1

There are lot of great inventions. The type of research strategy should they use is A/B Test, Switchback and Synthetic Control.

Uber is known to have so many ways to run experiment. They often applies several experimental methodologies in different cases as they are diverse in nature. They use them in testing out a new feature to improve the app design.

Uber's XP often gives room for engineers and data scientists to monitor treatment effects so as to make sure that they do not cause regressions of any key metrics.

EI is an essential component of interpersonal relationships and communication. People with high emotional intelligence are better equipped to understand the emotional needs of others, empathize with their emotions, and respond appropriately.

What is Emotional Intelligence?

Emotional intelligence (EI) is a vital skill in understanding and managing emotions, both in oneself and others. It allows individuals to recognize, comprehend, and regulate emotions in themselves and others, leading to better communication, decision-making, and social interactions.

The Myer-Briggs Type Indicator (MBTI) is a personality assessment tool that categorizes individuals into one of 16 personality types, based on four dichotomies: extraversion/introversion, sensing/intuition, thinking/feeling, and judging/perceiving. In this paper, I will discuss the role of emotional intelligence and how it relates to the MBTI personality types.

In conclusion, emotional intelligence is a critical skill in understanding and managing emotions in oneself and others.

The MBTI personality types can provide insight into how individuals may approach emotional intelligence, but all individuals can develop and improve their emotional intelligence through practice and reflection.

By doing so, individuals can improve their communication, decision-making, and social interactions, leading to greater personal and professional success.

A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.

Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.

Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.

Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.

The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.

The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.

Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.

Answers

The necessary conditions and procedures needed to accomplish this assignment is given below. Quicksort is an algorithm used to sort data in a fast and efficient manner.

What is the Quicksort?

Some rules to follow in the above work are:

A)Choose the initial element of the partition as the pivot.

b) Utilize the same method to select the pivot, but switch to insertion sort as the concluding step for partitions that contain 100 or fewer elements.

Lastly, Utilize the same method of pivot selection, but choose insertion sort for partitions that are of a size equal to or lesser than 50 in order to accomplish the task.
