The Patriots didn't draft a quarterback, but they signed two who went undrafted. Michigan State quarterback Brian Lewerke's agent revealed a week ago that Lewerke had signed with the Patriots. Patriots coach Bill Belichick wouldn't confirm the team had signed Louisiana Tech quarterback J'mar Smith as well. But Tuesday's official transactions report brought confirmation of [more]

The Jets announced on Wednesday that they have signed Lamar Jackson, but no one start frantically wondering what they missed regarding the 2019 NFL MVP. The Lamar Jackson that the Jets signed is an undrafted defensive back from Nebraska rather than the Ravens quarterback. The Jets' Jackson was second-team All-Big Ten last season after recording [more]

The NCAA is expected to formally approve rules changes that will allow athletes to get endorsement income in 2021.

The use of behavioural insights in public policy has traditionally focused on small, low cost 'nudges' to improve communications, increase compliance and enhance the way services are delivered. But BETA has begun to look beyond to identify a smaller set of 'richer veins' where BI can offer high financial and social impact. These areas includes consumer choice, financial decision-making and personal wellbeing.

The Anaheim Ducks have re-signed defensemen Christian Djoos and Jani Hakanpaa to one-year contracts. The Ducks announced the deals Wednesday. Djoos had one goal and two assists in nine games with the Ducks after they acquired him from the Washington Capitals on Feb. 24 in a trade for forward Daniel Sprong.

Ducks defensemen Christian Djoos and Jani Hakanpaa will stay with the team through the 2020-21 season after each signed a one-year, one-way contract extension.

Oregon State guard Mikayla Pivec is the epitome of a versatile player. Her 1,030 career rebounds were the most in school history, and she finished just one assist shy of becoming the first in OSU history to tally 1,500 points, 1,000 rebounds and 500 assists. She'll head to the WNBA looking to showcase her talents at the next level following the 2020 WNBA Draft.

CHICAGO (AP) -- Chicago State women’s coach Misty Opat resigned Thursday after two seasons and a 3-55 record.

Baylor has signed a transfer point guard for the third year in a row, and this one can play multiple seasons with the Lady Bears. Jaden Owens is transferring from UCLA after signing a national letter of intent with Baylor, which had graduate transfers at point guard each of the past two seasons. The Texas native just completed her freshman season with the Bruins and has three seasons of eligibility remaining.

Abstract:
We consider the problem of recovering linear image of unknown signal belonging to a given convex compact signal set from noisy observation of another linear image of the signal. We develop a simple generic efficiently computable non linear in observations “polyhedral” estimate along with computation-friendly techniques for its design and risk analysis. We demonstrate that under favorable circumstances the resulting estimate is provably near-optimal in the minimax sense, the “favorable circumstances” being less restrictive than the weakest known so far assumptions ensuring near-optimality of estimates which are linear in observations.

Abstract:
Singular value decomposition (SVD) based principal component analysis (PCA) breaks down in the high-dimensional and limited sample size regime below a certain critical eigen-SNR that depends on the dimensionality of the system and the number of samples. Below this critical eigen-SNR, the estimates returned by the SVD are asymptotically uncorrelated with the latent principal components. We consider a setting where the left singular vector of the underlying rank one signal matrix is assumed to be sparse and the right singular vector is assumed to be equisigned, that is, having either only nonnegative or only nonpositive entries. We consider six different algorithms for estimating the sparse principal component based on different statistical criteria and prove that by exploiting sparsity, we recover consistent estimates in the low eigen-SNR regime where the SVD fails. Our analysis reveals conditions under which a coordinate selection scheme based on a sum-type decision statistic outperforms schemes that utilize the $ell _{1}$ and $ell _{2}$ norm-based statistics. We derive lower bounds on the size of detectable coordinates of the principal left singular vector and utilize these lower bounds to derive lower bounds on the worst-case risk. Finally, we verify our findings with numerical simulations and a illustrate the performance with a video data where the interest is in identifying objects.

Abstract:
It is frequently of interest to identify simultaneous signals, defined as features that exhibit statistical significance across each of several independent experiments. For example, genes that are consistently differentially expressed across experiments in different animal species can reveal evolutionarily conserved biological mechanisms. However, in some problems the test statistics corresponding to these features can have complicated or unknown null distributions. This paper proposes a novel nonparametric false discovery rate control procedure that can identify simultaneous signals even without knowing these null distributions. The method is shown, theoretically and in simulations, to asymptotically control the false discovery rate. It was also used to identify genes that were both differentially expressed and proximal to differentially accessible chromatin in the brains of mice exposed to a conspecific intruder. The proposed method is available in the R package github.com/sdzhao/ssa.

Abstract:
We study the problem of estimating piecewise monotone vectors. This problem can be seen as a generalization of the isotonic regression that allows a small number of order-violating changepoints. We focus mainly on the performance of the nearly-isotonic regression proposed by Tibshirani et al. (2011). We derive risk bounds for the nearly-isotonic regression estimators that are adaptive to piecewise monotone signals. The estimator achieves a near minimax convergence rate over certain classes of piecewise monotone signals under a weak assumption. Furthermore, we present an algorithm that can be applied to the nearly-isotonic type estimators on general weighted graphs. The simulation results suggest that the nearly-isotonic regression performs as well as the ideal estimator that knows the true positions of changepoints.
