What are the best ways to explain dimensionality reduction to non-technical stakeholders?
Dimensionality reduction is a data analytics technique that simplifies complex data sets by reducing the number of features or variables. It can help improve the performance, accuracy, and interpretability of machine learning models, as well as reduce the computational cost and storage space. However, explaining dimensionality reduction to non-technical stakeholders can be challenging, especially if they are not familiar with the concepts of data, features, and models. In this article, you will learn some of the best ways to explain dimensionality reduction to non-technical stakeholders, using simple examples, analogies, and visualizations.
-
Use analogies:Explain dimensionality reduction like sharing the gist of a complex story. You distill a novel down to key points, keeping the essence for easier understanding and better decision-making.
-
Principal component analysis:This method ranks data features by their impact and keeps only the most influential ones. It's like focusing on the chapters of a book that drive the story forward, trimming the rest.
