Item-Focussed Trees for the Detection of Differential Item Functioning in Partial Credit Models [PDF]
arXiv, 2016 Various methods to detect differential item functioning (DIF) in item response models are available. However, most of the methods assume that the responses are binary, for ordered response categories available methods are scarce. In the present paper DIF in the widely used partial credit model is investigated.

Finding Words Associated with DIF: Predicting Differential Item Functioning using LLMs and Explainable AI [PDF]
arXivWe fine-tuned and compared several encoder-based Transformer large language models (LLM) to predict differential item functioning (DIF) from the item text. We then applied explainable artificial intelligence (XAI) methods to these models to identify specific words associated with DIF.

Item focussed Trees for the Identification of Items in Differential Item Functioning [PDF]
arXiv, 2015 A new method for the identification of differential item functioning (DIF) by using recursive partitioning techniques is proposed. We assume an extension of the Rasch model that allows for DIF being induced by an arbitrary number of covariates for each item.

Permanence of large eddies in variable-density homogeneous turbulence [PDF]
arXiv, 2019 The principle of permanence of large eddies is one of the central pillars onto which our understanding of decaying homogeneous turbulence is built. The validity conditions of this principle have been thoroughly discussed for constant density flows, but not for variable-density ones.

Non-unique Ergodicity for the 2D Stochastic Navier-Stokes Equations with Derivative of Space-Time White Noise [PDF]
arXivWe prove existence of infinitely many stationary solutions as well as ergodic stationary solutions for the stochastic Navier-Stokes equations on $\mathbb{T}^2$ \begin{align*} \dif u+\div(u\otimes u)\dif t+\nabla p\dif t&=\Delta u\dif t + (-\Delta)^{\fa/2}\dif B_t,\ \ \ \ \div u=0,\notag \end{align*} driven by derivative of space-time white noise ...

SAT-DIFF: A Tree Diffing Framework Using SAT Solving [PDF]
arXivComputing differences between tree-structured data is a critical but challenging problem in software analysis. In this paper, we propose a novel tree diffing approach called SatDiff, which reformulates the structural diffing problem into a MaxSAT problem.
