High-performance Physical Reservoir Computing with Multi-detection Chaotic Spin Wave Interference| MANAPrevious Index NextResearch Highlights[Vol. 85]High-performance Physical Reservoir Computing with Multi-detection Chaotic SpinWave Interference3 Oct, 2023Researchers from the Research Center for Materials Nanoarchitectonics (MANA) present the firstexperimental demonstration of a physical reservoir computing system based on spin waveinterference.Novel technologies are shaping the modern world, and artificial intelligence (AI) systems are expected toplay an important role in this transformation. Accordingly, demand for compact AI devices with lowpower consumption and high computational performance is growing rapidly. Recently, physical reservoircomputing, which relies on a physical system to efficiently process information, has emerged as apromising technology for ubiquitous AI implementation. To be considered suitable for reservoircomputing, the physical system must possess nonlinearity, short-term memory, and the ability to map inhigh dimensions. Notably, spin wave interference in ferromagnetic materials satisfies all three criteriaand is considered a promising candidate for efficient reservoir computing. However, its experimentalrealization has remained elusive so far.Now, a research team led by Principal Investigator Kazuya Terabe from MANA has experimentallydemonstrated a reservoir computing system based on multi-detection nonlinear spin wave interferencefor the first time. Their study involved Dr. Wataru Namiki as the first author and Dr. Takashi Tsuchiya asthe corresponding author.The team utilized an yttrium iron garnet single crystal with multi-antennas, which excited and detectedmulti-spin waves. The physical reservoir computing system showed excellent performance for a hand-written digit recognition task, second-order nonlinear dynamical tasks, and nonlinear autoregressivemoving average (NARMA); specifically, a maximum testing accuracy rate of 89.6% for hand-written digitResearchQuantum Materials FieldNanomaterials FieldResearch SupportResearch HighlightsHot TopicsHome  > Research  > Research Highlights  > Vol. 85 ･･･About MANA Research People News Room Outreach Employment AlumniSite Map Contact Us Access to MANA Website System Requirements   Text size  Standard Large  Japanese Page2024/07/16 13:38 High-performance Physical Reservoir Computing with Multi-detection Chaotic Spin Wave Interference| MANAhttps://www.nims.go.jp/mana/research/highlights/vol85.html 1/2https://www.nims.go.jp/mana/research/highlights/vol84.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/highlights/vol86.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/quantum_material.htmlhttps://www.nims.go.jp/mana/research/nano_material.htmlhttps://www.nims.go.jp/mana/research/researcher_support.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/hottopics/index.htmlhttps://www.nims.go.jp/mana/jp/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttp://www.jsps.go.jp/english/e-toplevel/http://www.jsps.go.jp/english/e-toplevel/https://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/about/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/member/index.htmlhttps://www.nims.go.jp/mana/news_room/2024.htmlhttps://www.nims.go.jp/mana/pror/index.htmlhttps://www.nims.go.jp/mana/recruit/index.htmlhttps://www.nims.go.jp/mana/alumni/index.htmlhttps://www.nims.go.jp/mana/siteinfo/sitemap.htmlhttps://www.nims.go.jp/mana/siteinfo/inquiry.htmlhttps://www.nims.go.jp/mana/siteinfo/access.htmlhttps://www.nims.go.jp/mana/siteinfo/accessibility.htmlhttps://www.nims.go.jp/mana/jp/research/highlights/vol85.htmlrecognition and normalized mean square errors (MSEs) of 8.37 x 10 to the power of minus 5 and 1.81 x10 to the power of minus 2 for the nonlinear dynamical tasks and NARMA2, respectively. Notably, theMSEs are the best figures reported for any experimental physical reservoir."The high performance can be attributed to a high nonlinearity and a large memory capacity of themulti-detection chaotic spin wave interference system. It can thus contribute to the implementation ofintegrated physical reservoir systems with real-world applications," concludes Dr. Tsuchiya.Reference“Experimental Demonstration of High-Performance Physical Reservoir Computing with NonlinearInterfered Spin Wave Multidetection”Wataru Namiki, Daiki Nishioka, Yu Yamaguchi, Takashi Tsuchiya and Kazuya TerabeJournal: Advanced Intelligent Systems (August 22, 2023)DOI : doi.org/10.1002/aisy.202300228AffiliationsResearch Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science(NIMS), Namiki 1-1, Tsukuba, Ibaraki 305-0044, JapanContact informationResearch Center for Materials Nanoarchitectonics (MANA)National Institute for Materials Science1-1 Namiki, Tsukuba, Ibaraki 305-0044 JapanPhone: +81-29-860-4710E-mail: mana-pr[AT]nims.go.jpTo receive our e-mail newsletter “MANA Research Highlights”, please send an e-mail with "MANA ResearchHighlights request” in the subject line or main text to the following address: mana-pr_at_nims.go.jp *Pleasechange "_at_ " in the email address to @.Research Center for Materials Nanoarchitectonics (MANA)National Institute for Materials Science (NIMS)1-1 Namiki Tsukuba, Ibaraki 305-0044 JAPAN+81-29-860-4709E-mail: mana[AT]nims.go.jpCopyright © National Institute for Materials Science.
