Dimensionality Reduction -- The more you have, the less you see!

Welcome to the second part of Humans Learning from Machines. In this series, we discuss the philosophical relevance of some interesting concepts in Artificial Intelligence. In part 1: The Curse of Dimensionality; More is not always better!, we explored how more data can affect learnability in terms of Computational Burden, the Volume of Space, Visualisation and Parameter Estimation. In this part, we discuss how to handle the curse of dimensionality and how we can apply these concepts to improve our well-being. As we wrapped up the first part, When we feel overwhelmed by the infinite dimensions of data surrounding us, we change our perspectives and see things from a different angle to separate noise and relevant information.
