bserve improvements across quality, robustness, compactness, and runtime. Results demonstrate that TILTED can enable capabilities comparable to baselines that are 2x larger, while highlighting weaknesses of neural field evaluation procedures.</font></div></div></div><div><font face="georgia, serif" color="#000000"><br></font></div><div><div class="gmail_default"><b><font color="#000000" face="georgia, serif">*********************************************************************************************</font></b></div><p class="MsoNormal" style="margin:0in 0in 8pt;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;line-height:15.6933px"><font face="georgia, serif" color="#000000"><b>Masks are optional in all common areas. </b><b>Full visitor guidance is available at <a href="http://ttic.edu/visitors" target="_blank">ttic.edu/visitors</a>.</b></font></p><p class="MsoNormal" style="margin:0in 0in 12pt;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;line-height:15.6933px"><b><font color="#000000" face="georgia, serif">*********************************************************************************************</font></b></p><p class="MsoNormal" style="margin:0in;line-height:normal;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial"><b><i><font color="#000000" face="georgia, serif"><span class="gmail-il">Research</span> at TTIC Seminar Series</font></i></b></p><p class="MsoNormal" style="margin:0in;line-height:normal;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial"><font color="#000000" face="georgia, serif"> </font></p><div class="gmail_default"><div dir="ltr"><div class="gmail_default"><div dir="ltr"><p class="MsoNormal" style="margin:0in;line-height:normal;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial"><font face="georgia, serif" color="#000000">TTIC is hosting a weekly seminar series presenting the <span class="gmail-il">research</span> currently underway at the Institute. Every week a different TTIC faculty member will present their <span class="gmail-il">research</span>.  The lectures are intended for students seeking <span class="gmail-il">research</span> topics and advisors and for the general TTIC and University of Chicago communities interested in hearing what their colleagues are up to.</font></p></div></div></div></div><font color="#888888" style="font-family:georgia,serif"><font color="#888888"><br style="font-family:Arial,Helvetica,sans-serif"></font></font></div></div><font color="#888888" style="font-family:georgia,serif"><div><br style="font-family:Arial,Helvetica,sans-serif"></div></font></div><div style="font-family:Arial,Helvetica,sans-serif"><br></div><span class="gmail_signature_prefix" style="font-family:Arial,Helvetica,sans-serif">--</span><br style="font-family:Arial,Helvetica,sans-serif"><div dir="ltr" class="gmail_signature" style="font-family:Arial,Helvetica,sans-serif"><div dir="ltr"><b><font color="#3d85c6">Brandie Jones </font></b><div><div><div><font color="#3d85c6"><b><i>Executive </i></b></font><b style="color:rgb(61,133,198)"><i>Administrative Assistant</i></b></div></div><div><font color="#3d85c6">Toyota Technological Institute</font></div><div><font color="#3d85c6">6045 S. Kenwood Avenue</font></div><div><font color="#3d85c6">Chicago, IL  60637</font></div></div><div><font color="#3d85c6"><a href="http://www.ttic.edu/" target="_blank">www.ttic.edu</a> </font></div></div></div></div></div>
