recommendations! Published in 2019 at "Applied stochastic models in business and industry"

DOI: 10.1002/asmb.2340

Abstract: Regularization methods, including Lasso, group Lasso and SCAD, typically focus on selecting variables with strong effects while ignoring weak signals. This may result in biased prediction, especially when weak signals outnumber strong signals. This paper… read more here.

DOI: 10.1016/j.cjph.2018.04.001

Abstract: Abstract Aiming at the poor detection rate of multi-frequency weak signals under a strong background of noise, a novel method based on adaptive stochastic resonance (SR) theory is proposed in this paper. The optimal parameters… read more here.

DOI: 10.1016/j.futures.2020.102543

Abstract: Abstract In this paper we propose a framework to re-think and widen the theoretical assumptions behind so-called weak signal theory in futures studies. This paper suggests that the present understanding of weak signals views the… read more here.
