De-Selection Bias Recommendation Algorithm Based on Propensity Score Estimation
There are various biases present in recommendation systems, and recommendation results that do not consider these biases are unfair to users, items, and platforms.

Efficient estimation and correction of selection-induced bias with order statistics [PDF]
Model selection aims to identify a sufficiently well performing model that is possibly simpler than the most complex model among a pool of candidates. However, the decision-making process itself can inadvertently introduce non-negligible bias when the cross-validation estimates of predictive performance are marred by excessive noise.

Measurement equivalence in mixed mode surveys
Surveys increasingly use mixed mode data collection (e.g., combining face-to-face and web) because this controls costs and helps to maintain good response rates.

As an epidemiologist, I also have a few concerns surrounding the methodologic issues of such study findings. One of the most essential components of a comprehensive tobacco control program is to disseminate the ...

A Robust Classifier Under Missing-Not-At-Random Sample Selection Bias [PDF]
The shift between the training and testing distributions is commonly due to sample selection bias, a type of bias caused by non-random sampling of examples to be included in the training set. Although there are many approaches proposed to learn a classifier under sample selection bias, few address the case where a subset of labels in the training set ...
