Objectives

This assignment will guide your learning process to ensure you can:

• Compare and contrast supervised and unsupervised learning approaches, understanding their key differences and appropriate applications in economic analysis. (CLO-B, CLO-E, MLO 1)
• Understand and interpret Principal Components Analysis (PCA) for dimensionality reduction and pattern discovery in high-dimensional economic data. (CLO-A, CLO-F, MLO 2)
• Analyze the challenges and applications of matrix completion techniques in handling missing data and recommender systems. (CLO-C, MLO 3)
• Evaluate different clustering approaches (K-means and hierarchical) and their applications in discovering natural groupings in economic data. (CLO-A, CLO-F, MLO 4)
• Interpret and validate results from unsupervised learning methods using appropriate visualization tools and metrics. (CLO-B, CLO-D, MLO 5)
• Communicate findings from unsupervised learning analyses effectively to stakeholders in economic contexts. (CLO-D, MLO 6)
  

(CLO) stands for Course Learning Objective. (MLO) stands for Module Learning Objective You will find a complete list of Course Learning Objectives in the Syllabus and on the Start Here: Course Overview page. Module Objectives are listed on the Module Introduction pages. Each Assignment Objective and Module Objective in this course has its associated course-level objective indicated in parentheses to clarify the relationship between the two.
