Exercise 1: Forecasting chicken wing demand The following data represents the weekly demand for chicken wings at a local restaurant during the past six weeks: Week 1 2 3 4 5 6 Demand 650 521 563 735 514 596 Complete the following: a. Forecast the demand for week 7 using a five-period Moving average. b. Forecast the demand for week 7 using a three-period weighted moving average. Use the following weights to obtain your forecast: o W1 = 0.5 o W2 = 0.3 o W3 = 0.2 c. Forecast the demand for week 7 using exponential smoothing. o Use an α value of 0.1 o Assume…
COMP-5411 FA & FB Fall 2019 Assignment 1 This is NOT a group assignment Due Date: Wednesday, October 9, 11:59 pm Late submission is NOT allowed. 1) Write a program that will open a data file (“data.csv”) containing multiple rows and columns (no missing value). Assume both your program and the data file are in the same directory so that explicitly mentioning the path is not required while loading the file. Each column represents a feature and each row is an instance. The dataset should have at least 2 continuous features, 1 categorical feature and 100 instances. Your program then…
Project 2: Range Average Query Due: Tuesday, October 8, before 9:00 pm Addenda You may find it easier to store sums (rather than averages) in the RAQ and BlockRAQ data structures. If you choose to do this, your query() function must convert sums to averages. Also, your dump() function should print sums, not averages. You will need to include the cmath library in raq.cpp to use the sqrt() function. You may also include iostream (needed by dump()) and iomanip (optional, but allows for formatting of output). Objectives In this project, you will implement two different solutions for the Range Average…
