Adaptively Denoising Discrete Two-way Layouts
The two-way layout with ordinal or nominal factors is a fundamental data-type that is widespread in the sciences, engineering, and informatics. The unrestricted least squares estimator for the means of a two-way layout is usually inadmissible under quadratic loss and the model of homoscedastic independent Gaussian errors. In statistical practice, this least squares estimator may be modified by ...
متن کاملLow Risk Fits to Discrete Incomplete Multi-way Layouts
The discrete multi-way layout is a widespread data-type associated with regression, experimental designs, gene or protein chips, digital images or videos, and more. A discrete multi-way layout has a finite number of factor level combinations. The layout may be unbalanced or incomplete or both. We consider candidate fits to an incomplete layout that are least squares fits to certain submodels in...
متن کاملThree Way Segmentation(⋆)
Introduction. This work is to be set within the study context of supervised classification tree-based model. This methodology, according to CART approach (Breiman et al. 1984) allows to build a tree-structure to describe the dependence links between an independent variable and a set of explicative variables in regression and classification matters. The advantages of binary segmentation are to b...
متن کاملQueue Layouts, Tree-Width, and Three-Dimensional Graph Drawing
A three-dimensional (straight-line grid) drawing of a graph represents the vertices by points in Z3 and the edges by non-crossing line segments. This research is motivated by the following open problem due to Felsner, Liotta, and Wismath [Graph Drawing ’01, Lecture Notes in Comput. Sci., 2002]: does every n-vertex planar graph have a three-dimensional drawing with O(n) volume? We prove that thi...
متن کاملHierarchical Layouts of Directed Graphs in Three Dimensions
We introduce a new graph drawing convention for 3D hierarchical drawings of directed graphs. The vertex set is partitioned into layers of vertices drawn in parallel planes. The vertex set is further partitioned into k ≥ 2 subsets, called walls. The layout consists of a set of parallel walls which are perpendicular to the set of parallel planes of the layers. We also outline a method for computi...
