ISYE 6501 Midterm 1 EXAM QUESTIONS WITH 100% SOLUTIONS LATEST UPDATE 2023/2024 True or false: In a regression tree, every leaf of the tree has a different regression model that might use different attributes, have different coefficients, etc. - ANSWER True - Each leaf's individual model is tailored to the subset of data points that follow all of the branches leading to the leaf. True or false: Tree-based approaches can be used for other models besides regression. - ANSWER True ...

The main objective is to write a fully executed R-Markdown program performing regression prediction for the response variable using the best models found for kNN, Random Forest and XGBoost techniques predicting the response variable in the Nutrition case study. Make sure to describe the final hyperparameter settings of all algorithms that were used for comparison purposes. You are required to clearly display and explain the models that were run for this task and their effect on the reduction of...

PyTorch for Burn and Not Burn Do these problems qualify or suitable for deep learning? why or why not? and How does Pytorch compares with KNN for Burn dataset? Include differences you can think of!

Problem: A healthcare facility (aka hospital) brought in a new research physician who specializes in treating burn victims. This physician has been tasked with running the hospital’s telemedicine division and is interested in using machine learning to triage patients who schedule appointments with the telemedicine service. As part of the triage process, patients are instructed to send in photographs of their skin, so that the most in-need patients can be treated first.

What do descriptive questions ask? - CORRECT ANSWER-What happened? (e.g., which customers are most alike) What do predictive questions ask? - CORRECT ANSWER-What will happen? (e.g., what will Google's stock price be?) What do prescriptive questions ask? - CORRECT ANSWER-What action(s) would be best? (e.g., where to put traffic lights) What is a model? - CORRECT ANSWER-Real-life situation expressed as math. What do classifiers help you do? - CORRECT ANSWER-differentiate What is a soft...

True or false: In a regression tree, every leaf of the tree has a different regression model that might use different attributes, have different coefficients, etc. - correct answer True - Each leaf's individual model is tailored to the subset of data points that follow all of the branches leading to the leaf. True or false: Tree-based approaches can be used for other models besides regression. - correct answer True - For example, a classification tree might have a different SVM or KNN ...
