However, realizing this promise poses significant computational and memory challenges, particularly for real-time applications on resource-constrained edge devices. Achieving ubiquitous 3D intelligence requires overcoming challenges related to efficiency, accessibility, and adaptability\u2014enabling \u201cevery application on every device, all at once.\u201d\u003C\/p\u003E\u003Cp\u003E\u003Cbr\u003ETo address these challenges, my dissertation focuses on how a unified insight into multi-granular algorithm\u2013hardware co-design, combined with the development of supporting research infrastructure, can help mitigate the aforementioned limitations. First, I introduce Instant-3D, which addresses the efficiency challenge. Instant-3D is a hardware\u2013algorithm co-design that optimizes both memory usage and access regularity for bottleneck operators, enabling instant on-device 3D reconstruction. Next, I present MixRT, which tackles the accessibility challenge. MixRT leverages operator-level heterogeneity to fully utilize commonly available hardware resources on modern GPUs, enabling real-time rendering across a wide range of edge devices\u2014from mobile phones to laptops. Then, I introduce Uni-Render, which targets the adaptability challenge. Uni-Render is a unified neural rendering accelerator that dynamically adjusts dataflows to meet diverse rendering metric requirements, achieving real-time rendering across five different models using a single accelerator consuming approximately five watts. Finally, I briefly discuss my contributions to building the supporting research infrastructure and conclude with a vision for the future of ubiquitous 3D intelligence. I also explore how the proposed innovations and infrastructure can be extended beyond 3D intelligence to advance more efficient, accessible, and adaptable AI.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EEnabling Ubiquitous 3D Intelligence via Multi-Granular Algorithm-Hardware Synergy\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Enabling Ubiquitous 3D Intelligence via Multi-Granular Algorithm-Hardware Synergy "}],"uid":"27707","created_gmt":"2025-04-16 13:05:07","changed_gmt":"2025-04-16 13:05:35","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-04-28T09:00:00-04:00","event_time_end":"2025-04-28T11:00:00-04:00","event_time_end_last":"2025-04-28T11:00:00-04:00","gmt_time_start":"2025-04-28 13:00:00","gmt_time_end":"2025-04-28 15:00:00","gmt_time_end_last":"2025-04-28 15:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Klaus 1212, Klaus Advanced Computing Building","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
