The text above is part of an interactive exercise where users can match various performance metrics with their definitions. Each metric, such as TPR/Recall, PPV/Precision, TNR/Specificity, and Accuracy, is provided with a dropdown option to select the corresponding definition. The definitions include details about the calculations for these metrics in the context of predictions and classifications.

Technology College Muscat hired you as a programmer to automate their manual Student Registration System. The college requires you to develop a C++ program to manage their Students' personal and academic record. You are required to develop a C++ program using C++ structures, arrays, and user defined functions. The college stores each student's full name, a maximum of 30 character long, student's age, numeric student's ID number of 8 digits long, student's modules enrolled and student's module result. You are required to implement 3 different functions, a function to get/input all the data of a student from a user. A function to get/input student's modules and result against each module and to calculate average marks of each students, and a function to display all students' personal and academic data.

Answer the given question with a proper explanation and step-by-step solution. For this question use the file data1.csv The file contains information on various customers. Each customer has a unique customer id. The data also has information on age income and Gender of the customers. Space can be used as a delimiter for this file. Find the following: A) The total number of the rows in the file. B) The number of unique customer ids in the datafile. For this question create a set object which will only allow you to add unique customer ids. C) The program asks user to provide an id and prints information about that customer. Make sure to take care for the errors due to invalid id (i.e., id does not present in data). Print “id not found” when id is not found. Save the file as Solution1.java. You can use either File Reader or Scanner classes to read the data in the csv file. Your program should print the following after filling the blanks with the appropriate values Outcome: The total…

The following dataset is a historic record of 14 houses that were sold in a small town in BC. The dataset is used to predict whether a new house in the same town will be sold in 10 days if listed with a specific price based on certain attributes. We are considering only four attributes (price, number of bedrooms, size, and distance to bus stop) just to simplify the calculations in this assignment but more attributes should be considered in real applications. House Price Number of Bedrooms Size (sqft) Distance to Bus-Stop House sold in 10 days? House 1 $300,000 1 3,500 sqft far No House 2 $300,000 1 3,500 sqft near No House 3 $250,000 1 3,500 sqft far Yes House 4 $350,000 2 3,500 sqft far Yes House 5 $350,000 3 5,000 sqft far Yes House 6 $350,000 3 5,000 sqft near No House 7 $250,000 3 5,000 sqft near Yes House 8 $300,000 2 3,500 sqft far No House 9…
