Explore how machine learning and data mining apply to business analytics, define the data mining process, and review exploratory data analysis and visualization with star discounts and market basket analysis.
Explore what business analytics, business intelligence, data mining, and big data mean and how the data mining process—from data preparation to deployment, including supervised and unsupervised learning—drives data-driven decisions.
Explore the basics of matrices and the EDA step in data mining, focusing on sampling, data quality, filling missing values, and creating binary dummy variables.
Explore big data visualizations through basic charts, multidimensional visuals, heat maps, scatter plot matrices, network graphs, and geographic maps, highlighting outliers, binning, and data transformation.
Fit and evaluate a multiple linear regression model on the West Roxbury housing data set, using training, test, and validation partitions to prevent overfitting, and assess with RMSE and MAE.
Explore decision trees and random forests for business analytics using the natural language toolkit (NLTK). Preprocess text with countvectorizer to predict discounts from reviews, description, and titles.
Explore market basket analysis with Apriori and associative rules to uncover frequent item sets and co-occurrence patterns, guiding merchandising through data mining metrics like support, confidence, and lift.
Explore the applications of data mining and machine learning in business analytics, and design models with Python or RStudio. Look for future Udemy courses with coding practice.
The course content is dedicated to the applications of machine learning and data mining to business analysis. The intent is to give a high-level overview of the potential of machine learning and data mining in different areas and, more specifically, the area of business analytics. The main sections are:
1. Core ideas of the data mining process - this section covers the definitions of the concepts of data mining, big data, business analytics and business intelligence.
2. Basics of exploratory data analysis - this section covers EDA with R.
3. Visualizing complex data sets - in this part the main visualizations used in business analytics and advanced data analysis are discussed in detail.
4. Housing valuation with multiple linear regression - this section covers the basic steps of the data mining process using housing valuation example.
5. Store discounts with random forest and natural language processing - in this section, the topic of machine learning methods, such as, decision trees and random forest, is examined. An example of store discounts is given to illustrate the application of natural language processing and random forest to text-rich data.
6. Market basket analysis with unsupervised machine learning - in this section unsupervised machine learning methods, such as, Apriori and associative rules are examined in detail. An example with market basket analysis is given to illustrate the application of Apriori and associative rules.
