For , a basic example of uniform convergence can be illustrated as follows: the sequence converges uniformly, while does not. Specifically, assume . Each function is less than or equal to when , regardless of the value of . On the other hand, is only less than or equal to at ever increasing values of when values of are selected closer and closer to 1 (explained more in depth further below).

WebInequalities play an important role in many areas of mathematics, including algebra, analysis, and optimization.Uniform Norms: A uniform norm is a way of measuring the size or magnitude of a function or sequence of functions. Specifically, the uniform norm of a function is defined as the maximum value that the function attains over a given domain.

WebWe prove that, indeed, uniform convergence bounds based on predictor norm cannot show any learning in this setting (Theorem 3.2).
