SharpeRatio@k, a novel evaluation metric for Off-Policy Evaluation estimators, effectively measures the risk-return tradeoff of evaluating policies used in reinforcement learning and contextual bandits, which are typically ignored by conventional metrics, show scientists at Tokyo Tech. This novel metric, inspired from risk assessment in financial portfolio management, provides a more insightful evaluation of OPE, paving […]
Graphical abstract. Credit: Green Energy and Intelligent Transportation (2023). DOI: 10.1016/j.geits.2023.100130 Researchers from the University of Missouri-Kansas City, School of Computing and Engineering, and independent researchers have developed a model, dubbed GREENSKY, that significantly enhances the energy efficiency and operational time of Unmanned Aerial Vehicles (UAVs) in cellular networks. In the ever-evolving landscape of wireless […]
Skema generasi EVB terstruktur. Masker fase holografik biner dapat direkayasa dengan fase spiral umum untuk membentuk elektron bebas yang datang untuk menghasilkan EVB terstruktur dengan pola intensitas yang dapat disesuaikan. Masker fase terdiri dari kisi-kisi bercabang skala nano yang dibuat pada membran silikon nitrida setebal 100 nm. Kredit: Kemajuan Opto-Elektronik (2024). DOI: […]
(a) Struktur kristal heterostruktur Bi/MnBi2Te4 vdW. (b) Diagram skematik yang menunjukkan magnetisme yang dapat dikontrol dan transisi fase topologi dalam material. Orientasi magnetisasi (Mi: i=x, y,z; panah merah) dapat disesuaikan dengan menerapkan regangan (dilambangkan dengan panah ungu) atau medan magnet. Keadaan QAH dengan bilangan Chern yang dapat dikontrol diwujudkan dengan mengubah orientasi magnetisasi atau memutar […]

Credit: Unsplash/CC0 Public Domain How do algorithms determine the way we interact with our memories? It’s a uniquely 21st-century kind of question, and it is far from settled. In a new paper in the journal Memory, Mind & Media, Concordia Ph.D. candidate Chrys Vilvang argues that the way tech companies store, package and share personal […]
Four elementary monotonic functions (exponential, logarithmic, square, and sine) were applied immediately after Coordinate-Wise Rank Transformation (CRT) and normalized to [-1, 1] in a coordinate-wise manner. The three circles on the radar plot correspond to the first-order Model Indistinguishability, the second-order Model Indistinguishability and the Mean Absolute Error of the exp(CRT) model (the largest among […]
