Inner Product Space Based on Fuzzy Neighborhoods for Text Data Analysis

Journal of Japan Society for Fuzzy Theory and Intelligent Informatics, 2009
ファジィ近傍モデルはテキストデータ解析のための手法である．既存手法であるベクトル空間法は，用語の出現頻度によってベクトル空間を生成するためのテキストの構造を反映していないと考えられるが，ファジィ近傍モデルはテキストのシーケンス構造を表現でき，さらにベクトル空間法やファジィ同値関係によるモデルの一般化となっている．この手法の利点は，ファジィ近傍に基づく正定値カーネルを生成できることである．これによりカーネルc-平均法やカーネル主成分分析など既存のテキスト分析手法を適用できる．この手法を用いて，新聞記事と医療因子インシデントレポートの２つの実データを解析した結果を示す．

Lattice-based Hierarchical Inner Product Encryption

, 2015
The notion of inner-product encryption (IPE), introduced by Katz, Sahai, and Waters at Eurocrypt 2008, is a generalization of identity-based encryption in which ciphertexts and secret keys are associated to vectors in some finite field. In an IPE scheme,

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Self‐Sensing Artificial‐Muscle‐Empowered Humanlike Perception, Interaction, and Positioning

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The proposed self‐sensorized artificial muscle (SSAM) can sense its length change as small as 0.01 mm via a seamlessly integrated multi‐segment induction coil. The SSAM provides accurate length information regardless of its loadings, driving pressure, or muscle design, adequate for robust data‐driven feedback control.
