Kernel Mean Embeddings: Turning Distributions into Points You Can Compute With

Most of machine learning is built around points. A data point is a vector, a model maps vectors to predictions, and distance between vectors tells you how similar two examples are. Distributions are harder. A distribution is not a point, it is a whole object: a function, a measure, a cloud of possible outcomes.

  • Kernel mean embeddings represent distributions as single points in high-dimensional function space.
  • Kernel function measures similarity between points, enabling operations on distributions as points.
  • Expectations of functions can be computed using inner products with kernel mean embeddings.
