Affine Transformation-Enhanced Multifactorial Optimization for Heterogeneous Problems

IEEE Transactions on Cybernetics, 2020
Evolutionary multitasking (EMT) is a newly emerging research topic in the community of evolutionary computation, which aims to improve the convergence characteristic across multiple distinct optimization tasks simultaneously by triggering knowledge ...

Multi-AUV Formation Reconfiguration Obstacle Avoidance Algorithm Based on Affine Transformation and Improved Artificial Potential Field Under Ocean Currents Disturbance

IEEE Transactions on Automation Science and Engineering
In this paper, the formation obstacle avoidance problem of autonomous underwater vehicles (AUVs) under the disturbances of ocean currents is studied. A variable formation reconfiguration and obstacle avoidance control scheme based on affine transform and

Affine Transformations in Affine Differential Geometry

Results in Mathematics, 1989
For a \(C^{\infty}\) hypersurface immersion f: \(M^ n\to R^{n+1}\), with M orientable, let \(\nabla\) be the affine connection induced by the affine normal and let h be the corresponding (first affine) fundamental form. The author studies the Lie subgroup of those affine transformations of M, with respect to \(\nabla\), that preserve h, namely \(G ...

Facial Image-to-Video Translation by a Hidden Affine Transformation

ACM Multimedia, 2019
There has been a prominent emergence of work on video prediction, aiming to extrapolate the future video frames from the past. Existing temporal-based methods are limited to certain numbers of frames.

Distributed Continuous-Time Algorithm for Time-Varying Optimization With Affine Formation Constraints

IEEE Transactions on Automatic Control, 2023
In this article, we investigate a continuous-time distributed optimization problem with time-varying cost functions and affine formation constraints, which are described by the stress matrices rather than the standard Laplacians.

Learning affine transformations

Pattern Recognition, 1999
Under the assumption of weak perspective, two views of the same planar object are related through an affine transformation. In this paper, we consider the problem of training a simple neural network to learn to predict the parameters of the affine transformation.

Affine Transformational Optics

Frontiers in Optics 2011/Laser Science XXVII, 2011
We describe a class of devices whose refractive index distribution results from an affine transformation over piece–wise uniform space, including theoretical analysis and experimental realizations using anisotropic materials and surface nanopatterning.
