Levin (University of Toront o, NVIDIA); and Changxi Zheng (Columbia University)\n\nWe introduce a nove l adaptive eigenvalue filtering strategy to stabilize and accelerate the o ptimization of Neo-Hookean energy and its variants under the Projected New ton framework. For the first time, we show that Newton’s method, Projected Newton with eigenvalue clamping and Projected Newton with absolute eigenv alue filtering can be unified using ideas from the\ngeneralized trust regi on method. Based on the trust-region fit, our model adaptively chooses the correct eigenvalue filtering strategy to apply during the optimization. O ur method is simple but effective, requiring only two lines of code change in the existing Projected Newton framework. We validate our model outperf orms stand-alone variants across a number of experiments\non quasistatic s imulation of deformable solids over a large dataset.\n\nRegistration Categ ory: Full Access, Full Access Supporter\n\nLanguage Format: English Langua ge\n\nSession Chair: Sheldon Andrews (École de technologie supérieure (ÉTS )) URL:https://asia.siggraph.org/2024/program/?id=papers_734&sess=sess141 END:VEVENT END:VCALENDAR
