The game theoretic p-Laplacian and semi-supervised learning with few labels

J Calder - Nonlinearity, 2018 - iopscience.iop.org
We study the game theoretic p-Laplacian for semi-supervised learning on graphs, and show
that it is well-posed in the limit of finite labeled data and infinite unlabeled data. In particular …

Consistency of Lipschitz learning with infinite unlabeled data and finite labeled data

J Calder - SIAM Journal on Mathematics of Data Science, 2019 - SIAM
We study the consistency of Lipschitz learning on graphs in the limit of infinite unlabeled
data and finite labeled data. Previous work has conjectured that Lipschitz learning is well …

Hamilton-Jacobi equations on graphs with applications to semi-supervised learning and data depth

J Calder, M Ettehad - Journal of Machine Learning Research, 2022 - jmlr.org
Shortest path graph distances are widely used in data science and machine learning, since
they can approximate the underlying geodesic distance on the data manifold. However, the …

Ranking vectors by means of the dominance degree matrix

Y Zhou, Z Chen, J Zhang - IEEE Transactions on Evolutionary …, 2016 - ieeexplore.ieee.org
In multi-/many-objective evolutionary algorithms (MOEAs), there are varieties of vector
ranking schemes, including nondominated sorting, dominance counting, and so on. Usually …

Pareto-depth for multiple-query image retrieval

KJ Hsiao, J Calder, AO Hero - IEEE Transactions on Image …, 2014 - ieeexplore.ieee.org
Most content-based image retrieval systems consider either one single query, or multiple
queries that include the same object or represent the same semantic information. In this …

Multicriteria similarity-based anomaly detection using Pareto depth analysis

KJ Hsiao, KS Xu, J Calder… - IEEE transactions on …, 2015 - ieeexplore.ieee.org
We consider the problem of identifying patterns in a data set that exhibits anomalous
behavior, often referred to as anomaly detection. Similarity-based anomaly detection …

A Hamilton--Jacobi equation for the continuum limit of nondominated sorting

J Calder, S Esedoglu, AO Hero - SIAM Journal on Mathematical Analysis, 2014 - SIAM
We show that nondominated sorting of a sequence X_1,\dots,X_n of independent and
identically distributed random variables in R^d has a continuum limit that corresponds to …

Directed last passage percolation with discontinuous weights

J Calder - Journal of Statistical Physics, 2015 - Springer
We prove that a directed last passage percolation model with discontinuous macroscopic
(non-random) inhomogeneities has a continuum limit that corresponds to solving a Hamilton …

Anomaly detection and classification for streaming data using PDEs

B Abbasi, J Calder, AM Oberman - SIAM Journal on Applied Mathematics, 2018 - SIAM
Nondominated sorting, also called Pareto depth analysis (PDA), is widely used in
multiobjective optimization and has recently found important applications in multicriteria …

Rates of convergence for the continuum limit of nondominated sorting

B Cook, J Calder - SIAM Journal on Mathematical Analysis, 2022 - SIAM
Nondominated sorting is a discrete process that sorts points in Euclidean space according to
the coordinatewise partial order and is used to rank feasible solutions to multiobjective …
