The 'blessing of dimensionality' is a counterphenomenon where high dimensionality can improve linear separability of random points and make contrast-loss beneficial when data arise from multiple generative processes.
Summary
Adding more dimensions to your data isn't always a problem; it can actually make it easier to separate different groups of points with a simple dividing boundary. This matters because it means contrast-based training methods become more effective when the data comes from multiple distinct sources rather than a single process, turning what the "curse of dimensionality" warns against into a useful advantage.
