Mis772 - Airbnbai - Rapidminer Assessment Answer

Assignment Task

AirbnbAI approached you again to develop a RapidMiner process predicting the overall satisfaction of customers renting the New York City AirBnB accommodation, i.e. 
overall_satisfaction (0..5, including fractions) 
AirbnbAI provided you with a sample of 882,000 listings of existing rentals and 803 of listings from Tom Slee’s AirBnB repository. The listings include the following information: 
Room id, name, type, price 
Id and name of the property host id and name 
Property geo-location, its neighbourhood and borough 
The number of reviews 
Minimum nights stay 
The number of occupants allowed in a rental 
Last date and time of posting (date of data collection) 
AirbnbAI would like you to use RapidMiner to generate some insights into the rental listings and these questions are of interests: 
A) Are there any trends in price and customer satisfaction? (by visualisation) B) What kind of properties receive what type of satisfaction level? (by clustering) C) What is the likely satisfaction level for the new rentals? (by estimation) 
AirbnbAI wants you to use RapidMiner to cleanup and explore the provided data, then develop and evaluate a estimator to predict the customer satisfaction, and to minimise RMSE, MAE and r2.

Individual Tasks and Deliverables 
Partial Submission (Question A - marked with the final submission) Exec Problem: Define your problem in business terms, in doing so answer question A, cross-reference with other report sections for support. Data Preparation: Deal with duplicates, bad and missing values by imputation. Transform the selected attributes or create the new ones as needed. Produce supporting charts and tables to answer question A. 
Final Submission (Questions B and C) Exec Solution: Describe your solution in business terms, in doing so answer questions B and C, cross-reference with other report sections. Data Exploration: Use clustering and segmentation analysis to investigate satisfaction with rentals. Deal with anomalies. Visualise clusters and anomalies. Provide support for question B. Model: Create three estimation models, i.e. linear regression, decision and an ensemble, to address question C. Explain operators properties. Evaluation and Optimisation: Optimise the model. Evaluate using cross- validation. Include a separate testing. Compare the performance of different models and select the best. Provide support for question C. Application: Apply the best model to new data and investigate results. Apply a model to a single listing and describe the results.
