Semi-supervised Spectral Connectivity Projection Pursuit [PDF]

open access: yes, 2015
We propose a projection pursuit method based on semi-supervised spectral connectivity. The projection index is given by the second eigenvalue of the graph Laplacian of the projected data.

Computing the Projection on the Intersection of Linear Equality and Cardinality Constraints

open access: yesIEEE Access
In this paper, we introduce a novel approach to solve the vector projection problem under linear equality and cardinality constraints, termed the Quasi-Newton Lagrangian method. This approach employs a Lagrangian transformation to address linear equality

Projected Canonical Curves and the Clifford Index

open access: yesPublications of the Research Institute for Mathematical Sciences, 2005
Let \(X\) be a smooth, nonhyperelliptic, projective algebraic curve, defined over \(\mathbb{C}\), and of genus \(g\). Denote by \(X^{(k)}\) the \(k\)-th symmetric product of \(X\), where \(k \in \mathbb{Z}\), \(k \geq 0\); points in \(X^{(k)}\) may be thought of as divisors on \(X\) that have degree \(k\) (we assume that \(X^{(0)}\) is a one point set ...

Geometric Residual Projection in Linear Regression: Rank-Aware Operators and a Geometric Multicollinearity Index

open access: yesMathematics
Residuals play a central role in linear regression, yet their geometry is often hidden by inverse- and pseudoinverse-based formulas. We develop a rank-aware framework for residual projection that makes the underlying orthogonality explicit.

Rotational Projection Errors in Coronal Knee Alignment on Weight-Bearing Whole-Leg Radiographs: A 3D CT Reference Across CPAK Morphotypes

open access: yesBioengineering
Whole-leg radiographs (WLRs) are widely used to assess coronal alignment before total knee arthroplasty (TKA), but may be inaccurate in patients with atypical morphotypes or malrotation.

PROJECT RISK INDEX FOR TRANSPORTATION PROJECT EVALUATION

open access: yesDoboku Gakkai Ronbunshu, 1994
プロジェクトの評価にあたって重要な不確実性の評価においては, 感度分析, リスク分析などの方法が使用されてきたが, それを実際に利用するには, 各事象の生起確率の推定などの困難があった. プロジェクトの実施を投資行為と考えて, それにオプションを設定することを考えれば, この不確実性を含めた評価指標が構成できる. この考え方に基づいて, プロジェクトリスクを含めた評価指標であるプロジェクトリスクインデックス (FRI) を提案し, その性質を解析した.
