Perspective maximum likelihood-type estimation via proximal decomposition

*Electronic Journal of Statistics*, *14*(1), 207–238.

author keywords: Convex optimization; heteroscedastic model; concomitant M-estimator; perspective function; proximal algorithm; robust regression

TL;DR:
An optimization model for maximum likelihood-type estimation (M-estimation) that generalizes a large class of existing statistical models, including Huber's concomitant M-estimator, Owen's Huber/Berhu concomant estimator, the scaled lasso, support vector machine regression, and penalized estimation with structured sparsity is introduced.

Optimal experimental design under irreducible uncertainty for linear inverse problems governed by PDEs

*INVERSE PROBLEMS*, *36*(7).

author keywords: optimal design; inverse problems; model uncertainty; optimization under uncertainty; model reduction; subsurface flow

TL;DR:
A novel formulation of the A-optimal design objective that requires the trace of an operator in the observation rather than the parameter space and is enforced using a weighted regularized ℓ0-sparsification approach.

The Douglas--Rachford Algorithm Converges Only Weakly

*SIAM Journal on Control and Optimization*, *58*(2), 1118–1120.

author keywords: Douglas-Rachford algorithm; method of partial inverses; monotone operator; operator splitting; strong convergence

TL;DR:
It is shown that the weak convergence of the Douglas--Rachford algorithm for finding a zero of the sum of two maximally monotone operators cannot be improved to strong convergence and strong convergence can fail for the method of partial inverses.

Uncertainty relations based on Wigner-Yanase skew information

*COMMUNICATIONS IN THEORETICAL PHYSICS*, *72*(7).

author keywords: uncertainty relations; skew information; entanglement

TL;DR:
This paper uses certain norm inequalities to obtain new uncertain relations based on the Wigner–Yanase skew information for an arbitrary finite number of observables and proposes new weighted uncertainty relations for two noncompatible observables.

A Sustainable Quantitative Stock Selection Strategy Based on Dynamic Factor Adjustment

*SUSTAINABILITY*, *12*(10).

author keywords: stock selection; machine learning; classification probability prediction; back-testing

TL;DR:
Historical back-testing using Chinese stock market data shows that the proposed CPP quantitative stock selection strategy performs better than the traditional machine learning stock selection methods, and it can outperform the market index over the same period in most back- testing periods.

*JOURNAL OF SYMBOLIC COMPUTATION*, *101*, 330–351.

author keywords: Subresultants; Algorithms; Complexity; Jacobi polynomials

TL;DR:
It is shown that the coefficients of the subresultants of ( x − α ) m and (x − β ) n with respect to the monomial basis can be computed in linear arithmetic complexity, which is faster than for arbitrary polynomials.
