Description:

Over the last two decades, we have seen an unprecedented increase in the volume of available information across various fields. This explosion encompasses data that is ultra-high-dimensional, complexly structured or unstructured, dynamic, and even derived from heterogeneous sources. These data are being produced, collected, stored, and made increasingly accessible to a wide range of stakeholders, including industrial institutions, academic researchers, investors, and individuals. However, learning from this vast trove of information and making accurate predictions poses significant challenges for both algorithm-driven machine learning methods and traditional statistical approaches. Key among these challenges is learning from data heterogeneity and implementing effective dimension reduction techniques without compromising the integrity of the data. This short course aims to lay the groundwork for understanding cluster analysis—an essential unsupervised statistical learning technique for uncovering data heterogeneity. It also covers Principal Component Analysis (PCA) and its variants, which are among the most prevalent tools for dimension reduction.
