Small ball probability, Inverse theorems, and applications [PDF]

open access: yes, 2012
Let $\xi$ be a real random variable with mean zero and variance one and $A={a_1,...,a_n}$ be a multi-set in $\R^d$. The random sum $$S_A := a_1 \xi_1 + ... + a_n \xi_n $$ where $\xi_i$ are iid copies of $\xi$ is of fundamental importance in probability

Phase Retrieval Without Small-Ball Probability Assumptions [PDF]

open access: yesIEEE Transactions on Information Theory, 2017
In the context of the phase retrieval problem, it is known that certain natural classes of measurements, such as Fourier measurements and random Bernoulli measurements, do not lead to the unique reconstruction of all possible signals, even in combination

Small ball probabilities for linear images of high dimensional distributions [PDF]

open access: yesInternational Mathematics Research Notices, 2014
We study concentration properties of random vectors of the form $AX$, where $X = (X_1, ..., X_n)$ has independent coordinates and $A$ is a given matrix. We show that the distribution of $AX$ is well spread in space whenever the distributions of $X_i$ are

Small ball probability and Dvoretzky theorem

open access: yesIsrael Journal of Mathematics, 2004
Large deviation estimates are by now a standard tool inthe Asymptotic Convex Geometry, contrary to small deviationresults. In this note we present a novel application of a smalldeviations inequality to a problem related to the diameters of random ...

Small ball probability for the condition number of random matrices [PDF]

open access: yes, 2019
Let $A$ be an $n\times n$ random matrix with i.i.d. entries of zero mean, unit variance and a bounded subgaussian moment. We show that the condition number $s_{\max}(A)/s_{\min}(A)$ satisfies the small ball probability estimate $${\mathbb P}\big\{s_{\max}

Optimal quantization of probabilities concentrated on small balls [PDF]

open access: yesForum Mathematicum, 2008
We consider probability distributions which are uniformly distributed on a disjoint union of balls with equal radius. For small enough radius the optimal quantization error is calculated explicitly in terms of the ball centroids.

Small ball probabilities for stable convolutions [PDF]

open access: yesESAIM: Probability and Statistics, 2007
Summary: We investigate the small deviations under various norms for stable processes defined by the convolution of a smooth function \(f : \; ]0, +\infty[ \;\to \mathbb{R} \) with a real \(S\alpha S\) Lévy process. We show that the small ball exponent is uniquely determined by the norm and by the behaviour of \(f\) at zero, which extends the results ...

Scanning, Contextual Factors, and Association With Performance in English Premier League Footballers: An Investigation Across a Season

open access: yesFrontiers in Psychology, 2020
Scanning in football (soccer) denotes an active head movement where a player’s face is temporarily directed away from the ball to gather information in preparation for subsequently engaging with the ball. The aim of this study was to learn more about the

Matchup models for the probability of a ground ball and a ground ball hit

open access: yesJournal of Sports Analytics, 2017
We develop matchup models for the probability of a ground ball and a ground ball hit using twelve years of major league baseball play-by-play data.
