A combination of different techniques in different parts of the pipeline provide significant savings. The techniques in Watch For can be broadly classified into three buckets.<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>End-to-end resource utilization optimizations:<\/strong> Watch For optimizes resources at cluster-level, node-level, and process-level. At the cluster-level, Watch For efficiently manages both spot and dedicated instances and orchestrates between them to process content at low cost and low latency. At the node-level, Watch For makes sure network and CPUs are effectively utilized. The system\u2019s workload is a combination of network and processing, and it applies a few techniques to keep utilization high.<\/li><li><strong>ML optimizations:<\/strong> Watch For does ML optimizations such as batching, model cascades, and bit-width optimizations. Watch For team has been working closely with OctoML and piloting Apache TVM as a model runtime to achieve high inference efficiency.<\/li><li><strong>Efficient programming templates:<\/strong> Watch For exposes efficient programming templates for various content types and pipelines written using those templates are efficiently executed at large scale. Watch For also exposes as many knobs to the developer as possible so that optimizations such as adaptive sampling and deduping can be easily implemented.<\/li><\/ol>\n\n\n","protected":false},"excerpt":{"rendered":"<p>Transitioned | Watch For is a large-scale, low-cost, highly programmable media analysis platform built on Azure.<\/p>\n","protected":false},"featured_media":767359,"template":"","meta":{"msr-url-field":"","msr-podcast-episode":"","msrModifiedDate":"","msrModifiedDateEnabled":false,"ep_exclude_from_search":false,"_classifai_error":"","footnotes":""},"research-area":[13556],"msr-locale":[268875],"msr-impact-theme":[],"msr-pillar":[],"class_list":["post-635574","msr-project","type-msr-project","status-publish","has-post-thumbnail","hentry","msr-research-area-artificial-intelligence","msr-locale-en_us","msr-archive-status-complete"],"msr_project_start":"","related-publications":[367685,496640,563634,767323,767335],"related-downloads":[],"related-videos":[],"related-groups":[],"related-events":[],"related-opportunities":[],"related-posts":[],"related-articles":[],"tab-content":[],"slides":[],"related-researchers":[{"type":"user_nicename","display_name":"Matthai Philipose","user_id":32834,"people_section":"Section name 0","alias":"matthaip"},{"type":"user_nicename","display_name":"Peter Bod\u00edk","user_id":33239,"people_section":"Section name 0","alias":"peterb"},{"type":"user_nicename","display_name":"Lenin Ravindranath Sivalingam","user_id":32645,"people_section":"Section name 0","alias":"lenin"},{"type":"guest","display_name":"Chris Linseman","user_id":632463,"people_section":"Section name 0","alias":""},{"type":"user_nicename","display_name":"Loc Huynh","user_id":38904,"people_section":"Section name 0","alias":"lohuynh"},{"type":"user_nicename","display_name":"Weishung Liu","user_id":39805,"people_section":"Section name 0","alias":"weisliu"},{"type":"guest","display_name":"Sahil Desai","user_id":727525,"people_section":"Section name 0","alias":""},{"type":"guest","display_name":"Mina Kim","user_id":727528,"people_section":"Section name 0","alias":""},{"type":"guest","display_name":"Disa Mhembere","user_id":746926,"people_section":"Section name 0","alias":""},{"type":"guest","display_name":"Saewon Kwak","user_id":763327,"people_section":"Section name 0","alias":""},{"type":"guest","display_name":"Casey Zhang","user_id":763324,"people_section":"Section name 0","alias":""}],"msr_research_lab":[199565],"msr_impact_theme":[],"_links":{"self":[{"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-project\/635574"}],"collection":[{"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-project"}],"about":[{"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/types\/msr-project"}],"version-history":[{"count":31,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-project\/635574\/revisions"}],"predecessor-version":[{"id":962961,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-project\/635574\/revisions\/962961"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/media\/767359"}],"wp:attachment":[{"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/media?parent=635574"}],"wp:term":[{"taxonomy":"msr-research-area","embeddable":true,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/research-area?post=635574"},{"taxonomy":"msr-locale","embeddable":true,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-locale?post=635574"},{"taxonomy":"msr-impact-theme","embeddable":true,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-impact-theme?post=635574"},{"taxonomy":"msr-pillar","embeddable":true,"href":"https:\/\/www.microsoft.com\/en-us\/research\/wp-json\/wp\/v2\/msr-pillar?post=635574"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
