Suppressing outliers in pairwise preference ranking

Vitor R. Carvalho, Jonathan L. Elsas, William W. Cohen, Jaime G. Carbonell
2008 Proceeding of the 17th ACM conference on Information and knowledge mining - CIKM '08  
Many of the recently proposed algorithms for learning feature-based ranking functions are based on the pairwise preference framework, in which instead of taking documents in isolation, document pairs are  ...  In this paper we study the effects of outlying pairs in rank learning with pairwise preferences and introduce a new meta-learning algorithm capable of suppressing these undesirable effects.  ...  Given the model learned, we calculated the pairwise decision scores P l [2] for all training data instances and constructed a histogram, as shown in the top of that the learned ranking model correctly  ...

Constrained Clustering and Multiple Kernel Learning without Pairwise Constraint Relaxation [article]

Benedikt Boecking, Vincent Jeanselme, Artur Dubrawski
2022 arXiv   pre-print
We introduce a new constrained clustering algorithm that jointly clusters data and learns a kernel in accordance with the available pairwise constraints.  ...  These pairwise constraints, which come in the form of must-link and cannot-link pairs, arise naturally in many applications and are intuitive for users to provide.  ...  In addition, for large datasets one may choose to downsample data for which no constraints are known to further reduce training complexity while learning an appropriate kernel.  ...

Active Learning to Rank using Pairwise Supervision [chapter]

Buyue Qian, Hongfei Li, Jun Wang, Xiang Wang, Ian Davidson
2013 Proceedings of the 2013 SIAM International Conference on Data Mining  
As the performance of a learnt ranking model is predominantly determined by the quality and quantity of training data, in this work we explore an active learning to rank approach.  ...  This paper investigates learning a ranking function using pairwise constraints in the context of human-machine interaction.  ...  In each trial, we randomly select 100 pairs as the initial training data to learn the ranking function.  ...

Rank-smoothed Pairwise Learning In Perceptual Quality Assessment [article]

Hossein Talebi, Ehsan Amid, Peyman Milanfar, Manfred K. Warmuth
2020 arXiv   pre-print
Training a model on these pairwise preferences is a common deep learning approach.  ...  However, optimizing by gradient descent through mini-batch learning means that the "global" ranking of the images is not explicitly taken into account.  ...  RankNet [14] is perhaps the most commonly used approach for learning to rank from pairwise comparisons.  ...

HybridDTA: Hybrid Data Fusion through Pairwise Training for Drug-Target Affinity Prediction [article]

Hongyu Luo, Yingfei Xiang, Xiaomin Fang, Wei Lin, Fan Wang, Hua Wu, Haifeng Wang
2021 bioRxiv   pre-print
Since the ranking orders of the affinity scores with respect to measurements and experimental batches are more consistent, we adopt a pairwise paradigm to enable the DNNs to learn from ranking orders instead  ...  We propose a novel paradigm for effective training on hybrid DTA data to alleviate the data inconsistency issue.  ...  Secondly, a pairwise training method is applied to optimize the model parameters of the DTA backbond by learning the orders of pairs.  ...

Case-Based Label Ranking [chapter]

Klaus Brinker, Eyke Hüllermeier
2006 Lecture Notes in Computer Science  
Label ranking studies the problem of learning a mapping from instances to rankings over a predefined set of labels.  ...  It exhibits the appealing property of transparency and is based on an aggregation model which allows to incorporate a broad class of pairwise loss functions on label ranking.  ...  If the training data would offer the utility scores directly, preference learning in the label ranking scenario would reduce to a standard regression problem.  ...
