Among those streaming online providers, Netflix became the world\u2019s leading Internet television network and the most-valued streaming service, which urges them to personalize users\u2019 experience more correctly with the help of recommendation system.&nbsp;<\/p>\n\n\n\n<p>However, with the overload of vast amounts of customer data, recommender systems face challenges in processing data robustly and accurately. Moreover, missing values in matrix or sparsity is another challenge . In this paper, instead of using built-in function of Singular Value Decomposition (SVD)-based algorithms for recommender systems, I built Asymmetric SVD and tuned its hyper-parameters, expecting to make an improvement in prediction accuracy and running time.<\/p>\n\n\n\n<p><strong>Data Architecture Diagram<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_2-3-1-1024x576.png\" alt=\"\" class=\"wp-image-4961\" srcset=\"https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_2-3-1-1024x576.png 1024w, https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_2-3-1-300x169.png 300w, https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_2-3-1-768x432.png 768w, https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_2-3-1-1536x864.png 1536w, https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_2-3-1.png 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>Senior Capstone Poster<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/zdnguyen18-CS488-Capstone_Final.pdf\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong><a href=\"https:\/\/youtu.be\/SYulEglaKlQ\">Software Demonstration Video<\/a><\/strong><\/p>\n\n\n\n<p><strong><a href=\"https:\/\/portfolios.cs.earlham.edu\/wp-content\/uploads\/2022\/05\/CS488_FinalPaper.pdf\">Tuned Asymmetric SVD Paper<\/a><\/strong><\/p>\n\n\n\n<p><a href=\"https:\/\/code.cs.earlham.edu\/zdnguyen18\/tuned_asymmetricsvd\"><strong>Tuned Asymmetric GitLab<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;m Winnie Nguyen, a senior majoring in Computer Science and Quantitative Economics at Earlham College.
