ATA MINING Homework: Clustering andMonte Carlo SimulationYou should return a Python notebook with your code and the answers to the questions. You are provided with a dataset that includes information about various movies such as budget, IMBD score, duration etc.: A- . Provide a good clustering for the data and a description of them (i.e., what type of movies do they include) Hint: Examine up to 20 clusters.b. As you will observe, the various features of the data are in different scales. In these cases, normalizing the data helps into obtaining better models – either supervised or unsupervised. Use the sklearn.preprocessing.normalize function to normalize the data and perform the clustering again. What do you observe? c. Visualize the data on a 2D scatter plot, where each point corresponds to a movie and movies that belong to the same cluster have the same color. What do you observe with regards to their visual separability? budgetgrossruntimescorevotes800000052287414898.12991746000000701363691037.8264740150000001.8E+081106.923690918500000851602481378.4540152900000018564613906.93663660000001.39E+081208.131758525000000127299171017.4102879600000085512281207.8146768900000040471663966.8605651500000040456565967.512969888000001.75E+08976.5794651600000059000001167.2104860600000082000001006.8122282500000011100000997.31016781500000086209291207.2540001700000067348441175.931798100000007433663985.4248812500000038747385946.95332727000003500000935.91163535000000162957741104.636020200000013167232826255171100000091258000966.62312047000008025872895.62125315000000427240171306.832954250000001.1E+081197.366366040697761986.647068071534871307.8869910241598721175.3113042500000079817937945.94299719000004600000997.11286225000000392467341046.4574062500000049042224875.754851020038221207.41456224500000172180231257.547497138000005229398211976249501.15E+081135.958370071774311146.5462360000005844868977.3361911000000037499651916.341278300000019472057865.92831025000000143027791176.623076047483002806.941004400000028265231127.1250321000000047112201053.8440145000001261000866.71663618000000413828411036.3285291900000040996665915.72066911000005450815824.375690385007261076.593440262855441065.910239111000609939837253671800000096977391075.6114846400000400840411078569881400000038600000747.2365398500000162094591065.52485160000005849647847.33360902015882917.240395000000591366886.8160771200000048846631005.5587805839031997.1114156000000286075241147.63660403006531498.116571650000023470001117116070154483841106.11041204662137855.612803014481606935.31002220000000253142891086.17570150000001953732985.3534012000000177689001255.61581908988731915.554190387023101136.2123070278200001045.26440013431806936.41158106797218985.8458518000000366116101126.2996502514705510364943043579163835.2354431750007137502846.65257071624879936.922554870000048659121096.32297051866461106.438660318530801197.2125381200000015945534885.69040110000014360001077.83945610000000206037151096.714502013245219907.19178083629691146.9131861800000039000001176.14666500000012947763896.211458250000001579260944.833970176853071026.6100220255878041055.8157034000000016418251216.1659605274807.8790010000000214582291046.25584020695211078959066375651005.440451200000077909311045.9552320000007369373985.7474414000000621342251036.11356985000002776461367.25364076349091055.637200595845686621250916172875.758431800000013051141155.736070123039041065.7556408033397825.655490320256835.7462003751699994.47491057941841047.4107470323245571185.953458000000118343021045475204834601176264933000004941117935.9390903151936.740720214831167.34922046361691036.612641500000012308521964.9504940000000498515911165.9837401476356966.69689013418091896.327051300000084754661005.64573024440761014.5680049409391208.12091402510433945.2171703940542113817849170000002315683973.143391600000038000001115.722870604849845.9102320000000229055001056.4307902278264915.5300604601256964.5142202147228963.32003600000099476311005.93561025451429073885010090429984.925490278623955.9183409302111085.62659032726001337.44028400000046796501045.9180802995527965.43400112132885.82243048457241024128405099316935.4101604781448975.6142618000000119579431086.92720037455987.8461203136701975.5327017204501005.9208001131399905.421570441863967.6184006029824904.51164078068882.989502037811557.326940277405865.73230239073855.315401409801025.29782500000040072501275.5134002750741934.69731700000027932141015.51358012540401015.868402750001005.49070142050211065.723000681337914.712650537681907.8233008540346765.317601400000018034150976.31288019437511005.363234013763388020974.31509100000006947787834.47920544472907.21623026693661024.151508736107769905633581075.56520444746886.2639040798951026.11032014926895.37950750000966.6162507250001057.82991019027061017.3662204743287885.7553015000001006.21672200000013011211115.944804163931056.682101777378936.56040925952847202205838001006.227501814101005.1310

![Exercise 4A Write functions to perform the following tasks efficiently. Do not change the function names in the template file, and do not import any packages besides those already indicated in the template. (1) Take x and return 2x^3. (2) Take two inputs x and y and return their product and the absolute value of their difference, in that order. E.g. inputs 3,4 should return 12,1. (3) The geometric mean of n numbers is the nth root of their product. The mid-range is the ordinary (arithmetic) mean of the maximum and minimum elements. Write a function which takes a list of numbers as input and returns True if the geometric mean is less than or equal to the midrange, and False if the geometric mean is greater than the midrange. For example, the input [3,8,9] should return True and [3,6,7,5] should return False. (4) Take an integer n and return a list of the first n terms of the Padovan sequence pn. (This is a variant of the Fibonacci numbers, defined by p[1] = p[2] = p[3] = 1, and p[n] = p[n-2] + p[n-3] for n>=4.) (5) Take a pair r0 and theta representing a point's polar coordinates and return a pair (x,y) representing its Cartesian coordinates. (6) Take a pair (x,y) representing a point's Cartesian coordinates and return a pair (r, theta) representing its polar coordinates, where theta is in the range [0,2π). Check that your function works for (x,y) in all quadrants.](https://gotit-pro.com/wp-content/uploads/2023/10/69b0fd8b-79ad-4a6a-ac52-c635ef316302.jpg)

![Large Integers Part #1 Largelnteger Class An array can be used to store large integers, one digit at a time. For example, the integer 1234 could be stored in the array num by setting num[0] to 1, num[1] to 2, num[2] to 3, num[3] to 4. However, for this class implementation, you might find it more useful to store the digits backward; that is, place 4 in num[0], 3 in num[1], 2 in num[2], and 1 in num[3]. For the sake of simplicity, we will be storing and manipulating only with positive large integers. Implement a class named Largelnteger that stores a large integer as an array of its digits. Class must extend HasState class (provided). This is needed to make sure clone() method is written correctly. Class must have the following: - Fields - Constant arraySize must be set to 23 - Partially filled array of integers of length 23 - int digitCount keeps the number of digits in large integer, e.t. how many elements of the partially filled array are used to store the number - No-argument constructor that stores number 0 in the array. Sets digitCount to 1 - Constructor that takes a string as a parameter. The constructor parses the given string and converts it into Large Integer by storing digits in the partially filled array. - Create a new custom Exception class called LargelntegerNumberFormatException. The constructor throws exceptions of this type when - string is too long to be stored as a 23-digit number or - when string is empty or - when the string contains non-digits and thus cannot be converted into a number. - Constructor that takes a number of type long as a parameter and builds an object from it by storing digits in an array. - This constructor also throws a custom LargelntegerNumberFormatException when a parameter passed to the constructor is a negative number. - getDigitCount() accessor to the digit count variable. - toString() method that converts an array into a string of numbers in the correct order. Number 12345 is converted into a string "12345" - add(Largelnteger) method that returns the sum of this integer and the one passed as a parameter. The method adds two large integers by implementing the usual "paper and pencil" addition algorithm. This is when the backward storage arrangement of those numbers in arrays will pay off. Carry-over will be easier to do when the integer is stored backward. - Create another custom Exception class called LargelntegerOverflowException. If the resulting number is more than 23 digits long, the add() method throws a LargelntegerOverflowException type exception. - Implement clone() method. - Make your class implement Relatable interface. Code of the interface is provided. Implement all three methods of the Relatable interface. Part #2 Polymorphic Class This class exists only to house one static method called isSorted(). The method must take an array of objects of type Relatable and check if the array is sorted with the help of methods of Relatable interface. The method returns true if the array is sorted and false if it is not. The whole purpose of this exercise is to illustrate the concept of polymorphism. The purpose of this class is to house three static methods. 1. Method void writeLargelntegerArray(Largelnteger[], String) takes an array of Large Integers and a name of a file as parameters. The method writes the contents of the given array into the given binary file (in binary mode). The method throws IOExceptions. The IOExceptions may originate in the methods but must not be handled. Instead, they must be propagated to the calling code. - Make sure to add implements Serializable to the Largelnteger class header. Binary IO will fail to work without that. 2. Method Largelnteger[] readLargelntegerArray(String) method reads the contents of a binary file with the given name as an array of objects of type Largelnteger. Assume you do not know the amount of data in the file. Read data one Largelnteger object at a time and store the objects in ArrayList first. After the end of the file has been reached, convert the ArrayList into a regular array of objects that can be returned from the method. - Please study EOFDemo.java code example to learn how to use exceptions when checking for the end of the file while reading from a binary file. - This method also throws IOExceptions. The IOExceptions may originate in the methods but must not be handled. Instead, they must be propagated to the calling code. 3. Method Largelnteger addLargelntegersFromFile(String) takes a text file name as a parameter. It reads an arbitrary number of strings of text from the file, converting them into Largelntegers as it reads. The Large Integers are added one by one to the running total with the help of add() method. The sum of all the Large Integers stored in the file as strings is then returned from the method. - The structure of the file may be imperfect. Some strings may contain corrupted data and will fail to be converted into Largelnteger. This must not interrupt the process of reading from the file. The corrupted string must be skipped over, and the next string must be read and converted. Use a try/catch block to catch and ignore LargelntegerNumberFormatException. - The sum of all numbers stored in the file may become too big to be stored in a Large Integer. In that case, a LargeIntegerOverflowException exception will be thrown by the add() method. If this happens, catch the exception and return a null value from the method. - This method also throws IOExceptions. The IOExceptions may originate in the methods but must not be handled. Instead, they must be propagated to the calling code.](https://gotit-pro.com/wp-content/uploads/2023/10/a2443259-5cf9-45ff-9909-fdcfa036711f.png)
![5. Write a program that implements a class called MyTeam. Your class should have the following private data items: Id (int), Name (string), Slogan (string), Wins (int), and Losses (int). You need to define properties with appropriate accessor functions for each of the data items. Methods should include a default constructor that sets values to the empty string or zero, a constructor that allows the user to specify all values for the data items, a member method called DisplayTeamInfo that outputs all the information for the given toy in a reasonable format.

![2.1 Problem Statement Recently at a University, there has been a huge increase in the number of enrollments. All records of students are entered into a flat file by the registrar when the students register and updated accordingly if there is a need. As a result of the increase in enrollments, this file now has a lot of records. Hence, the statistical officers are now finding it hard to analyze this file to produce various reports for the management. You are required to write a program which will read in this file and produce various reports as outlined. Input File: The input file called StudentRec.txt contains a list of student records. Each record is on a single line and the fields are separated by spaces. The names of the fields are: - Lastname - string - Firstname (initial) - char - ID# - integer - Year of birth - integer - GPA - double An example record may have the following form: Doe J 2021123419903.2 And the format of the actual file is shown below. (Note: the file doesn't show all records and for clarity, fields here are shown separated by tabs, but in the actual file they are separated by spaces). Assume that the file can have a maximum of 300 records. - The first three lines are just header lines and can be discarded - Student id contains an 8-digit number. - Year of birth contains a 4-digit number - GPA is a one decimal place number between 0 - 4 Program Requirements: 1. You must read this file from the current directory and store the records of students into appropriate arrays. 2. Your program should then be able to process the following commands. i.e. the program should provide the user with the following menu. - 1. Print the entire list as per the read file. - 2. Print the entire list with the inclusion of last name initial and age. - 3. Print the list sorted by GPA. - 4. Print the list of students which match a given lastname initial. - 5. Calculate and display the corresponding degree classification (according to GPA) as provided in Table A. - 6. Produce a file called Enrollments.txt (in the current directory), with all the details [Last name, Lastname Initial, Firstname Initial, ID#, Age, GPA, and degree classification]. - 7. Exit the program. Explanation of each menu item. 1. Print the entire class list. This menu item is selected by typing 1, and it should simply print the contents of the file in a suitable format on the screen. (Fields (columns) to display in output are: Last name, Firstname Initial, ID#, Age, GPA, and degree classification) 2. Print the entire class list with the inclusion of last name initial and age. This menu item is selected by typing 2, and it should simply print the contents of the file in a suitable format on the screen with the inclusion of last name initial and age. (Fields (columns) to display in the output are: Last name, Lastname Initial, Firstname Initial, ID#, Age, and GPA) 3. Print the class list sorted by GPA. This menu item is selected by typing 3. The program then prints the list in ascending order of GPA. (Fields (columns) to display in the output are: Lastname Initial, ID#, and GPA) 4. Print the class list of students which match a given lastname initial. The user selects this option by typing 4. Then the user is asked to enter the search initial. If there are students who have that initial, the program prints their record. Otherwise, if no students have last names matching the search initial, a "no matching record found" message is displayed. (Fields (columns) to display in the output are: lastname and id) 5. Calculate and display the corresponding degree classification as per GPA as provided in Table A. The user selects this option by typing 5. The program then calculates and displays the degree classification according to GPA. The format of the resultant display is shown below: [The table (Table A) for degree classification as per GPA is given at the end of this project description] 6. Produce a file called Enrollments.txt (in the current directory), with all the details [Last name, Lastname Initial, Firstname Initial, ID#, Age, GPA, and degree classification]. The user selects this option by typing 6. The program then generates a file "Enrollments.txt" in the current directory with the following details [Last name, Lastname Initial, Firstname Initial, ID#, Age, GPA, and degree classification]. 7. Exit the program. User selects this option by typing 7. This is when the program should end. Note: After each command is processed (except menu 7), the program must display the menu options again. Function to sort an array: There are many algorithms to sort an array according to an ascending or descending criterion. However, we will use the following as it is easiest to understand and CODE. Minimum Element Sort: Go through the array and find the smallest element. Swap it with the first element of the array. Now find the smallest element of the rest of the array and swap it with the second element of the array. And so on. Rather more formally: to sort (x0, ..., xn) into ascending order for i=0 to n-1 begin find the smallest of (xi, ..., xn)](https://gotit-pro.com/wp-content/uploads/2023/10/862ab19f-4f11-467e-ac53-58e56050ee1f.jpg)
