Sparse Minimum Redundancy Maximum Relevance for Feature Selection

Scandinavian Journal of Statistics, EarlyView.
ABSTRACT We propose a feature screening method that integrates both feature–feature and feature–target relationships. Inactive features are identified via a penalized minimum Redundancy Maximum Relevance (mRMR) procedure, which is the continuous version of the classical mRMR penalized by a non‐convex regularizer, and where the parameters estimated as ...

Signature Schemes in the Quantum Random-Oracle Model

, 2017
A signature scheme is a fundamental component in modern digital communication. It allows for authenticated messages, without which it would be nearly impossible to ensure security when using most modern technologies. However, there is a growing threat to

Calibration of Retrospective and Prospective Life Satisfaction Judgments Around the World

FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 2, August 2026.
ABSTRACT It is both a physical and psychological fact that humans have access to records of the past but not to records of the future. Due to this epistemic asymmetry in time, we hypothesized that retrospection about past psychological states will be better calibrated than prospection about future psychological states.

Analysis of collision probability in Merkle trees in the random oracle model

Journal of Mathematical Cryptology
This work analyzes the probability of collisions in Merkle graphs, with a focus on a specific class of attacks in balanced Merkle trees. To provide a tractable model, each hash function is modeled as an independent random oracle with finite input space ...

Rendering transparency to ranking in educational assessment via Bayesian comparative judgement

Review of Education, Volume 14, Issue 2, August 2026.
Abstract Transparency in educational assessment has become an increasingly pressing concern, particularly in the aftermath of the pandemic, as institutions seek more equitable, robust and defensible methods of evaluating student work. Comparative judgement (CJ) has gained traction as a promising alternative to traditional rubric‐based marking. However,
