In this talk, I will discuss some of my work in this area, focusing on new convergence guarantees obtained via a proximal algorithm for sampling, as well as a new framework for studying the complexity of non-log-concave sampling.<o:p></o:p></span></p><p style='margin:0in;box-sizing: inherit'><strong><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></strong></p><p style='margin:0in'><strong><span style='font-family:"Arial",sans-serif;font-weight:normal'>In-Person seminars will be held at Mason Lab 211, 9 Hillhouse Avenue with the option of virtual participation (</span></strong><b><span style='font-family:"Arial",sans-serif'><a href="https://yale.hosted.panopto.com/Panopto/Pages/Sessions/List.aspx?folderID=f8b73c34-a27b-42a7-a073-af2d00f90ffa"><span style='color:windowtext;text-decoration:none'>https://yale.hosted.panopto.com/Panopto/Pages/Sessions/List.aspx?folderID=f8b73c34-a27b-42a7-a073-af2d00f90ffa</span></a>)<o:p></o:p></span></b></p><p style='margin:0in;box-sizing: inherit'><strong><span style='font-family:"Arial",sans-serif'><a href="https://0.0.0.10/"><span style='color:windowtext;font-weight:normal;text-decoration:none'>3:30pm</span></a></span></strong><strong><span style='font-family:"Arial",sans-serif;font-weight:normal'> - Pre-talk meet and greet teatime - Dana House, 24 Hillhouse Avenue<i> </i></span></strong><b><span style='font-family:"Arial",sans-serif'><o:p></o:p></span></b></p><h2 style='margin:0in;box-sizing: inherit;font-feature-settings: "kern", "liga", "dlig"'><span style='font-family:"Arial",sans-serif;font-weight:normal'><o:p> </o:p></span></h2><p class=MsoNormal style='background:white;vertical-align:baseline'><span style='font-size:12.0pt;font-family:"Arial",sans-serif;color:black;mso-fareast-language:JA'>For more details and upcoming events visit our website at <a href="http://statistics.yale.edu/" target="_blank"><span style='color:#0563C1'>http://statistics.yale.edu/</span></a> .</span><span style='font-size:12.0pt;font-family:"Arial",sans-serif;mso-fareast-language:JA'><o:p></o:p></span></p><h2 style='margin:0in'><span style='font-family:"Arial",sans-serif;font-weight:normal'><o:p> </o:p></span></h2><h2 style='margin:0in'><span style='font-family:"Arial",sans-serif;font-weight:normal'><o:p> </o:p></span></h2><h2 style='margin:0in'><span style='font-family:"Arial",sans-serif;font-weight:normal'><o:p> </o:p></span></h2><h2 style='margin:0in'><span style='font-family:"Arial",sans-serif;font-weight:normal'>Department of Statistics and Data Science<o:p></o:p></span></h2><p style='margin:0in;box-sizing: inherit'><span style='font-size:9.0pt;font-family:"Arial",sans-serif;color:black'>Yale University<br>24 Hillhouse Avenue<br>New Haven, CT 06511<o:p></o:p></span></p><p style='margin:0in;box-sizing: inherit'><span style='font-size:9.0pt;font-family:"Arial",sans-serif;color:black'>t 203.432.0666<br>f 203.432.0633<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:12.0pt;font-family:"Arial",sans-serif;mso-fareast-language:JA'> <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:12.0pt;font-family:"Arial",sans-serif;mso-fareast-language:JA'> <o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:JA'><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
