A proximal algorithm is one whose basic iterations involve the proximal operator of some function, whose evaluation requires solving a specific optimization problem that is typically easier than the original problem. Many familiar algorithms can be cast in this form, and this &ldquo;proximal view&rdquo; turns out to provide a set of broad organizing principles for many algorithms useful in statistics and machine learning. In this paper, we show how a number of recent advances in this area can inform modern statistical practice. We focus on several main themes: (1) variable splitting strategies and the augmented Lagrangian; (2) the broad utility of envelope (or variational) representations of objective functions; (3) proximal algorithms for composite objective functions; and (4) the surprisingly large number of functions for which there are closed-form solutions of proximal operators. We illustrate our methodology with regularized logistic and Poisson regression incorporating a nonconvex bridge penalty and a fused Lasso penalty. We also discuss several related issues, including the convergence of nondescent algorithms, acceleration and optimization for nonconvex functions. Finally, we provide directions for future research in this exciting area at the intersection of statistics and optimization.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A6946202">Cited in <strong>39</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A62J07" title="MSC2020">62J07</a> </td> <td class="space"> Ridge regression; shrinkage estimators (Lasso) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A90C25" title="MSC2020">90C25</a> </td> <td class="space"> Convex programming </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3ABayes+MAP">Bayes MAP</a>; <a href="/?q=ut%3Ashrinkage">shrinkage</a>; <a href="/?q=ut%3Asparsity">sparsity</a>; <a href="/?q=ut%3Asplitting">splitting</a>; <a href="/?q=ut%3AKurdyka-%C5%81ojasiewicz">Kurdyka-Łojasiewicz</a>; <a href="/?q=ut%3Anonconvex">nonconvex</a>; <a href="/?q=ut%3Aenvelopes">envelopes</a>; <a href="/?q=ut%3Aregularization">regularization</a>; <a href="/?q=ut%3AADMM">ADMM</a>; <a href="/?q=ut%3Aoptimization">optimization</a>; <a href="/?q=ut%3Adivide+and+concur">divide and concur</a></div> <!-- Modal used to show zbmath metadata in different output formats--> <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;"> <!-- alert for connection errors etc --> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function"> <!-- Button trigger metadata modal --> <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1426.62213" data-ciurl="/ci/06946202" data-biburl="/bibtex/06946202.bib" data-amsurl="/amsrefs/06946202.bib" data-xmlurl="/xml/06946202.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/06946202.pdf" title="Zbl 1426.62213 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.1214/15-STS530" aria-label="DOI for “Proximal algorithms in statistics and machine learning”" title="10.1214/15-STS530">DOI</a> <a class="btn btn-default btn-xs" type="button" href="https://arxiv.org/abs/1502.03175"title="Note: arXiv document may differ from published version">arXiv</a> <a class="btn btn-default btn-xs" type="button" href="https://projecteuclid.org/euclid.ss/1449670858" title="Full Text at Project Euclid">Euclid</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Allain, M., Idier, J. and Goussard, Y.
