 3473 Multilinear Regression
The Multilinear Regression process used actual red and green component rasters of the San Francisco area created from the San Francisco SPOT XS raster object to produce the predicted blue component raster shown.
Note that an inverted mask appears as fl in the output, the same as a mask that is not inverted; the color of the inverted mask shown is edited to a medium gray shade for illustration purposes.
The red component predicted by multilinear regression replaced the actual red component in one composite (left); the predicted blue component replaced the actual blue component in another composite (middle); the predicted green component replaced the actual green component in a third composite (right).

 Tufts University | Computer Science Department -- Colloquia >> Colloquia
In the context of computer vision and graphics, we deal with natural images which are the consequence of multiple factors related to scene structure, illumination, and imaging.
I will present two multilinear models that learn (nonlinear) manifold representations of image ensembles in which the multiple constituent factors (or modes) are disentangled and analyzed explicitly.
In graphics, our image-based rendering technique, called TensorTextures, is a multilinear generative model that, from a sparse set of example images of a surface, learns the interaction between viewpoint, illumination and geometry, which determines surface appearance, including complex details such as self-occlusion and self shadowing.

 CSAIL Research Abstract
The key obstacle in constructing a multilinear model is the vast amount of data (in full correspondence) needed to account for every possible combination of attribute settings.
For the control problem, we show how to connect this model to cheaper sources of data such as video, so that the model can be applied to performances by actors who are not in the original database and not available for detailed measurement.
An intriguing prospect is that, by scanning faces of different ages, we can build a multilinear model that gives us control over an actor's aparent age (identity x expression x age).

 Between Linearity and Nonlinearity
One approach to the hypertext essay that attempts to steer a course between the linear and nonlinear is a multilinear approach to writing hypertext.
An alternative multilinear approach might afford the user more control over initial navigation through a less suggestive organizational structure, while imposing greater control over the user's options once a node is selected.
The argument is both textual and visual, making it something of a new media multilinear research essay and a good example of Davis and Shadle's "multi-writing" (434).

 MERL – Multilinear Face Models
A multilinear face model is a simple function that can generate a wide variety of realistic face images.
Therefore we set out to develop methods to estimate multilinear models from facial scan data, to recover multilinear facial parameters from ordinary video, and to resynthesize such videos with interesting changes.
Technical Discussion: We estimated a multilinear model from a set of high-resolution 3D face scans taken of several people in various expressions and speech articulations.

 Multilinear Subspace Analysis of Image Ensembles   (Site not responding. Last check: 2007-10-16)
Multilinear algebra, the algebra of higher-order tensors, offers a potent mathematical framework for analyzing ensembles of images resulting from the interaction of any number of underlying factors.
This N-mode orthogonal iteration algorithm is based on a tensor decomposition known as the N-mode SVD, the natural extension to tensors of the conventional matrix singular value decomposition (SVD).
We demonstrate the power of multilinear subspace analysis in the context of facial image ensembles, where the relevant factors include different faces, expressions, viewpoints, and illuminations.

The individual reader is empowered with multiple options of how to proceed through the material; he or she may easily choose an idiosyncratic manner of reading it and so experience an utterly different "text" than does another reader.
Multilinearity: Theorists have pointed out that "nonlinear" does not adequately describe reading of any kind because letters and words are parsed sequentially regardless of the length of the textual chunk.

Abstract: An arithmetic circuit or formula is multilinear if the polynomial computed at each of its wires is multilinear.
We give an explicit example for a polynomial $f(x_1,...,x_n)$, with coefficients in ${0,1}$, such that over any field: 1) $f$ can be computed by a polynomial-size multilinear circuit of depth $O(log^2 n)$.
This gives a super-polynomial gap between multilinear circuit and formula size, and separates multilinear $NC_1$ circuits from multilinear $NC_2$ circuits.

 Multilinear IF
IF offers a little extra leeway, however: people (at least in my experience) tend to have less rigorous expectations of the plot and pacing than they would if they were dealing with a written story, and if the ending makes sense based on the outcome of the last several turns, they seem relatively content.
What I didn't anticipate was how many people would be made nervous by the multilinearity.
Perhaps it's the puzzle-solving nature of IF-players, but much of my feedback has come in the form of the question, "These are the endings I found: have I got them all?"

 multilinear data modeling
Robert T. Ross Department of Biochemistry, The Ohio State University, 484 West 12th Avenue, Columbus OH 43210 USA Internet: rtr+@osu.edu edition of 01 Feb 95 This document describes a family of programs written by the author to fit multilinear models to data in 2-way, 3-way, and 4- way arrays.
CHOICES OF ARRAY WAYS: In many multilinear models, two or more ways can be interchanged and the resulting permuted model is the same type of multilinear model.
In many circumstances, including the unmodified use of general multilinear models such as Parafac, T2, and T3, the values of the independent variables, XI, XJ, and XK, are not used in the model, and thus may be assigned dummy values.
