The Mean-Field Limit of Online Stochastic Vector Balancing

Christian Fiedler, Joe Jackson, Daniel Lacker +1

We study an online vector balancing problem, in which $n$ independent Gaussian random vectors $ζ (1), \dots, ζ (n) \sim N (0, I_{n})$ , each of dimension $n…

Fuk-Nagaev inequality in smooth Banach spaces: Optimum bounds for distributions of heavy-tailed martingales

Mattes Mollenhauer, Christian Fiedler

We derive a Fuk-Nagaev inequality for the maxima of norms of martingale sequences in smooth Banach spaces which allow for a finite number of higher conditional moments. The bound i…
