- Use python machine learning. A group of data scientists want to analyze some data. They already cleaned up the data, with the result being a Dataframe called X_train. The Dataframe X_train has 1058 rows and 13 columns. It has the below columns (picture attached on how it looks like): 'LotFrontage','LotArea','BsmtFinSF1', 'BsmtFinSF2', 'BsmtUnfSF','TotalBsmtSF','1stFlrSF', '2ndFlrSF', 'LowQualFinSF', 'GrLivArea','TotRmsAbvGrd','GarageArea','OpenPorchSF' Answer the following questions: 1. Transform X_train using PCA. Assign the output to a variable X_train_pca. 2. What is wrong with above approach? Scale the data, then repeat the above.Please help me interpret this.Right now we have a CourseListType that will hold a static 50 courses. Now we need to make that a little more flexible. To do that we want to change the static array to a dynamic array. So, what do we need to do? Modify CourseListType so that it contains a pointer to a CourseType rather than an array of CourseType. Modify the CourseListType constructor to create a dynamic array allocating space for a specific number of CourseType elements rather than always using 50. (Note: This is still not totally flexible, but is much better than a static limit.) Finally, we need to create a destructor to for CourseListType to deallocate space whenever a declared object goes out of scope.) //courseListType.h file #ifndef COURSELISTTYPE_H_INCLUDED#define COURSELISTTYPE_H_INCLUDED #include <string>#include "courseType.h" class courseTypeList { public:void print() const;void addCourse(std::string);courseTypeList(); private:static const int NUM_COURSES = 50;int courseCount;courseType…
- Implement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.KNN is a technique used to estimate new values based on the similarity of known ones. In this assignment, your company wants you to estimate the selling price of a customer's building The price you calculate will be given to the customer as the company selling price recommendation. You decide to use Data Science techniques such as the K-Nearest Neighbor.(KNN) You will need to: Import the necessary libraries from your program. (You can use the model class sklearn.neighbors.KNeighborsClassifier, part of the package sci-kit-learn 1.1.1 (Links to an external site) or any other. Train/test the model with the data included in the module (cal_housing.tgz). The house you need to estimate the value for has the following properties: longitude: 120.75latitude: 39.34housingMedianAge: 35.5total rooms: 260totalBedrooms:120 population:540households: 12medianIncome:1.8 K BuildingValue: ? What is the recommended price? You need to provide the code, properly commented. You could use…Instrument FrequencyCounter to use Stopwatch and StdDraw to make a plot where the x-axis is the number of calls on get() or put() and the y-axis is the total running time, with a point plotted of the cumulative time after each call. Run your program for Tale of Two Cities using SequentialSearchST and again using BinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.
- In this program, you are provided with phenotype counts of F1 and F2 offspring at two research institutes. The data are generated from an initial parental cross of elegant cranes, whose genetics are identical to fruit flies, with the exception that they look like crane birds. The cranes for each institute come from the same original source. For each institute, in the parental generation (P0), one parent displays the wild-type (WT) phenotype and one the disease phenotype. The WT parent always has a homozygous genotype, and whether the disease parent has a homozygous genotype depends on which scenario describes data in the F1 generation. The possibilities for F1 individuals are: (a) All individuals are disease; (b) All individuals are wild-type; (c) There are disease and wild-type individuals. When both disease and WT individuals (item (c)) are available in the F1 generation then you should use the F1 cross, (disease) X WT. For each institute, there are three possible modes of…After your interviews at Google and Microsoft, you started getting comfortable with the interview process and wanted to give it a try with Amazon as well. As Amazon makes more money by selling items to people, regardless of people really need those items or not, they are interested in suggesting ”related” items to the query word of a user. It also happens that people make typos such that the letters are typed out of order. You are given a list of n words, which consists of words that are used in the names of items sold on Amazon. You are being asked to suggest a data structure to store these words in memory, which will efficiently suggest words that are consisting of the same letters as the query word in constant time. For example, if the user is searching for ”silent”, you should suggest the word ”listen”, among other words that are stored in your data structure. What sort of a data structure would you use? Why? Explain the advantage of using this data structure for that problem.…Generating statistics from a set of data is a task that computers love. In this assignment, you will be implementing a grade processing system that will generate the mean and standard deviation for a set of final exam grades. We will assume that final grades are stored in a list, where each entry in the list is a string with the following format: "studentNum-finalGrade%" The string represents the final exam mark (finalGrade) that the student (studentNum) achieved. For example, the cell below contains a list of final exam marks from two students. Student 1007089 achieved a mark of 91%, and student 1009989 achieved a mark of 77.5%. grades = ['1007089-91%','1009989-77.5%' ] We want to calculate the mean final exam mark from a list of grades. If we assume that we have N grades, the mean x can be calculated from the following formula: N-1 1 (1) i=0 The variable x; represents each grade in our list at index i. We assume that we start counting at 0. We also want to be able to calculate the…
- A basic wooden railway set contains the pieces shown in figure below. It identifies the quantityof each type of piece denoted by ‘x’. Each piece is not uniquely identified by a primary keyvalue only labeled by type. i.e., Input information only states quantity of types such as twelvestraight pieces, two branch pieces, two merge pieces, and sixteen curve pieces. Pieces connect the knob to opening, with subtend curves extending the arc from start to end by45 degrees, and the pieces can be flipped over for track direction. The task is to connect these pieces into a railway that has no overlapping tracks and no looseends where a train could run off onto the floor. Question: Suppose that the pieces fit together exactly with no slack. Give a precise formulation of thetask as a search problem. Write a Java algorithm to assemble optimally solving the problem.Split blood pressure into systolic and diastolic blood pressure with integer as data type readings and remove the original column. Examine the data and look for predictor columns that are indicator variables, 0 or 1. Convert the data type to Boolean. Using code prepare lists of predictor column names for each data type. Make sure all the predictor columns are included in one and only one list. Print the length of the list of each data type and the sum of the lengths and verify that all predictor variables are accounted for in the lists. Use f-string to align the numbers properly.Design and implement a service that simulates PHP loops. Each of the three loop variants should be encapsulated in an object. The service can be controlled via a parameter and execute three different simulations. The result is returned as JSON. The input is an array consisting of the letters $characters = [A-Z]. -The For loop should store all even letters in an array.-The Foreach loop simulation is to create a backward sorted array by For loop, i.e. [Z-A] .-The While loop should write all characters into an array until the desired character is found. Interface:-GET Parameter String: loopType ( possible values: REVERSE, EVEN, UNTIL )-GET parameter String: until (up to which character) Output:JSON Object: {loopName: <string>, result: <array> }
