Defining the Curse
As you explore high-dimensional data, you quickly discover that your geometric intuition from lower dimensions breaks down. In earlier chapters, you saw how the volume of a shape like a sphere or cube behaves strangely as dimensions increase, and how the distances between points begin to concentrate. These effects are not just mathematical curiosities — they reveal a deeper challenge known as the curse of dimensionality. This "curse" describes how the complexity of data analysis grows rapidly as the number of dimensions increases, making many standard techniques ineffective or misleading. The intuition is that as you add more dimensions, the space expands so quickly that data points become increasingly isolated, and the volume of the space becomes overwhelmingly large compared to the amount of data you can realistically collect.
The curse of dimensionality refers to the exponential growth of volume with each added dimension, which leads to data becoming extremely sparse. This sparsity makes it difficult to find meaningful patterns, as points are far apart and most of the space is empty.
