Heavy tails and pruning in programmable photonic circuits for universal unitaries [PDF]
Nature Communications, 2022 Developing hardware for high-dimensional unitary operators plays a vital role in implementing quantum computations and deep learning accelerations.

Linear Regression for Heavy Tails [PDF]
Risks, 2018 There exist several estimators of the regression line in the simple linear regression: Least Squares, Least Absolute Deviation, Right Median, Theil–Sen, Weighted Balance, and Least Trimmed Squares.

Heavy loads and heavy tails [PDF]
Indagationes Mathematicae, 2023 The present paper is concerned with the stationary workload of queues with heavy-tailed (regularly varying) characteristics. We adopt a transform perspective to illuminate a close connection between the tail asymptotics and heavy-traffic limit in infinite-variance scenarios. This serves as a tribute to some of the pioneering results of J.W.

Fluctuating landscapes and heavy tails in animal behavior [PDF]
PRX Life, 2023 Animal behavior is shaped by a myriad of mechanisms acting on a wide range of scales. This immense variability hampers quantitative reasoning and renders the identification of universal principles elusive.

Filtering with heavy tails [PDF]
Journal of the American Statistical Association, 2012 An unobserved components model in which the signal is buried in noise that is non-Gaussian may throw up observations that, when judged by the Gaussian yardstick, are outliers.

Understanding heavy tails in a bounded world or, is a truncated heavy tail heavy or not? [PDF]
Stochastic Models, 2009 We address the important question of the extent to which random variables and vectors with truncated power tails retain the characteristic features of random variables and vectors with power tails. We define two truncation regimes, soft truncation regime

Outliers and the Ostensibly Heavy Tails [PDF]
Mathematical Methods of Statistics, 2018 The aim of the paper is to show that the presence of one possible type of outliers is not connected to that of heavy tails of the distribution. In contrary, typical situation for outliers appearance is the case of compactly supported distributions.

Covariance Estimation: Optimal Dimension-free Guarantees for Adversarial Corruption and Heavy Tails [PDF]
Journal of the European Mathematical Society (Print), 2022 We provide an estimator of the covariance matrix that achieves the optimal rate of convergence (up to constant factors) in the operator norm under two standard notions of data contamination: We allow the adversary to corrupt an $\eta$-fraction of the ...

Parameter-free Regret in High Probability with Heavy Tails [PDF]
Neural Information Processing Systems, 2022 We present new algorithms for online convex optimization over unbounded domains that obtain parameter-free regret in high-probability given access only to potentially heavy-tailed subgradient estimates.

Active gels, heavy tails, and the cytoskeleton. [PDF]
Soft Matter, 2021 The eukaryotic cell's cytoskeleton is a prototypical example of an active material: objects embedded within it are driven by molecular motors acting on the cytoskeleton, leading to anomalous diffusive behavior.
