Novel methodologies are introduced by integrating stochastic optimal control, spectral perturbation analysis, decentralized optimization and game-theoretic frameworks into online decision-making problems that face massive reconfiguration penalties. Algorithms derived from these techniques yield robust, distribution-agnostic performance guarantees across centralized and multi-agent settings. Furthermore, these approaches are shown to achieve substantial real-world gains in critical domains like decentralized dynamic network slicing and learning-augmented scheduling for AI workloads.\u003C\/p\u003E\u003Cp\u003ESpread across six chapters, the first three focus on online convex optimization with unbounded metric switching costs, with the fourth chapter demonstrating operational gains in the network slicing domain. The next two chapters shift focus to the online workload scheduling problem, first presenting state-of-the-art robustness guarantees and then applying them to public cloud services to realize real cost savings. Together, these results present a principled approach for handling reconfiguration overheads in dynamic large-scale systems.\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESequential Decision Making at Scale: Theory and Applications\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Sequential Decision Making at Scale: Theory and Applications"}],"uid":"27707","created_gmt":"2026-05-27 14:59:16","changed_gmt":"2026-05-27 15:01:07","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-06-05T13:00:00-04:00","event_time_end":"2026-06-05T15:00:00-04:00","event_time_end_last":"2026-06-05T15:00:00-04:00","gmt_time_start":"2026-06-05 17:00:00","gmt_time_end":"2026-06-05 19:00:00","gmt_time_end_last":"2026-06-05 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"ISyE Groseclose Building, Room 304","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":""}}}
