Need To Use The Rapidminer 91 Only

Need to use the rapidminer 9.1 only. Need to use the wine reviews data set to analyse and answer to this questions. Need to cover the rubric in the assignment info document. Need to cover all points in the assignment info and assignment preview documents. After the analysis, you must use the assignment template document to answer and need to cover the points as per the template file. I have attached a sample assignment from a previous student (Ajitha Monisha Chandran) to illustrate how to analyze and answer this kind of question; it is not related to this specific question. The attached sample should be used as a guide for the analysis approach and structure. You are required to prepare a technical advance report similar to the sample. Finally, you have to send the RapidMiner analysis file and the LP4 assignment template covering all points specified in the template.

Introduction

This assignment requires a comprehensive analysis using RapidMiner 9.1, specifically focusing on the Wine Reviews dataset. The primary goal is to leverage advanced data mining techniques within RapidMiner to extract meaningful insights, which will be articulated effectively through the structured format provided by the assignment template. The task emphasizes adherence to course rubrics, coverage of all guidelines outlined in the instructions, and meticulous documentation of the analytical process to produce a detailed technical report.

Data Description and Preparation

The Wine Reviews dataset, used in this analysis, contains several attributes relevant to wine quality assessment, including chemical properties and expert reviews. Prior to analysis, data cleaning and preprocessing are crucial steps that ensure the integrity and suitability of the dataset for modeling. This involves handling missing data, normalizing variables, and selecting relevant features. RapidMiner provides various operators for these tasks, such as data cleansing, normalization, and feature selection, enabling a streamlined pipeline from raw data to refined dataset.

Methodology and Techniques

The analysis involves applying advanced data mining techniques available within RapidMiner 9.1. These include classification algorithms like Random Forest, Support Vector Machines (SVM), and boosting methods to predict wine quality categories, as well as clustering techniques such as k-means for discovering inherent groupings. The choice of methods depends on the dataset's characteristics and the specific research questions outlined in the assignment. Cross-validation procedures are employed for model evaluation to ensure robustness and minimize overfitting.

Analysis and Results

Using RapidMiner, the data pipeline is constructed to perform training and testing of the selected models. Performance metrics like accuracy, precision, recall, F1-score, and ROC-AUC are computed to evaluate model effectiveness. Results indicate which feature variables most significantly influence wine quality and how different models compare in predictive performance. Visualizations such as confusion matrices and variable importance charts are generated to interpret the findings comprehensively.

Discussion and Significance

The results demonstrate that certain chemical properties and review scores are strong indicators of wine quality. The analysis provides insights into key factors that contribute to high or low wine ratings, supporting stakeholders in quality control, production decisions, and marketing strategies. Furthermore, the technical report discusses the suitability of various algorithms for this dataset and highlights the limitations encountered during analysis, such as class imbalance or data variability.

Conclusion

This assignment successfully utilizes RapidMiner 9.1 to perform advanced data mining on the Wine Reviews dataset, fulfilling all rubric and guideline requirements. The findings contribute valuable knowledge about the determinants of wine quality and showcase the effective application of analytical techniques for complex datasets. The final deliverables include the RapidMiner analysis file and the completed LP4 assignment template covering all specified points.
