FEBS Open Bio, EarlyView.ZNF469 regulates the expression of genes encoding extracellular matrix proteins. Endogenous ZNF469 is predominantly cytoplasmic, while in transfected cells, it forms aggregates reminiscent of biomolecular condensates, located mainly in the nucleus. These condensates exhibit overlapping staining with proteasomes and are also associated with the mitotic ...

DIFFERENTIAL ITEM FUNCTIONING (KEBERBEDAAN FUNGSI BUTIR)
Lentera Pendidikan: Jurnal Ilmu Tarbiyah dan Keguruan, 2017 This paper theoretically deals some aspects related to Differential Item Functioning (DIF), consisting of Test and Test Bias. The purpose of this is to describe the importance of understanding Different Item Functioning or to discuss its existence. Based

FoundationsIn fixed item parameter calibration (FIPC), an item response theory (IRT) model is estimated with item parameters fixed at reference values to estimate the distribution parameters within a specific group.

NISER: Normalized Item and Session Representations to Handle Popularity Bias [PDF]
arXiv, 2019 The goal of session-based recommendation (SR) models is to utilize the information from past actions (e.g. item/product clicks) in a session to recommend items that a user is likely to click next. Recently it has been shown that the sequence of item interactions in a session can be modeled as graph-structured data to better account for complex item ...

Improving IRT Item Bias Detection With Iterative Linking and Ability Scale Purification
, 1990 The effectiveness of several iterative methods of item response theory (IRT) item bias detection was examined in a simulation study. The situations em ployed were based on biased items created using a two-dimensional IRT model.

An Iterative Procedure for Linking Metrics and Assessing Item Bias in Item Response Theory
, 1988 The presence of biased items may seriously affect methods used to link metrics in item response theory. An iterative procedure designed to minimize this methodological problem was examined in a monte carlo investigation using the two-parameter item re ...

A Short Note on Aberrant Responses Bias in Item Response Theory
Frontiers in Psychology, 2019 Item response models often cannot calculate true individual response probabilities because of the existence of response disturbances (such as guessing and cheating).

Addressing the Multistakeholder Impact of Popularity Bias in Recommendation Through Calibration [PDF]
arXiv, 2020 Popularity bias is a well-known phenomenon in recommender systems: popular items are recommended even more frequently than their popularity would warrant, amplifying long-tail effects already present in many recommendation domains. Prior research has examined various approaches for mitigating popularity bias and enhancing the recommendation of long ...
