We derive tight non-asymptotic bounds for the Kolmogorov distance between the probabilities of two Gaussian elements to hit a ball in a Hilbert space. The key property of these bounds is that they are dimension-free and depend on the nuclear (Schatten-one) norm of the difference between the...

Historical examples (ISDN, Teletex, telefax, telex) show us that forecasting efforts in the telecommunication sector can go awry - not only by a few percentage points but by large magnitudes. We maintain that with strong network effects it is not possible to forecast the success of...
