TASFAR adapts regression models without labeled source data.
New method adapts without backprop, faster and better.
New method restores source features for SFDA without source data.
CUTS removes corruption from models without clean data, improving utility and security.
The Goldberg-Sachs theorem is generalized for all four-dimensional manifolds endowed with torsion-free connection compatible with the metric, the treatment includes all signatures as well as complex manifolds. It is shown that when the Weyl tensor is algebraically special severe geometric restrictions are imposed. In p…
Ancient solutions found for a specific flow on symplectic half-flat structures.
This paper is the first attempt to formalize a new field of economics; studding the Intangibles Goods available on the Internet. We are taking advantage of the digital world's specific rules, in particular the zero marginal cost, to propose a theory of trading & sharing unified. A function based money is created as a w…
Ehlers-Kundt conjecture is a physical assertion about the fundamental role of plane waves for the description of gravitational waves. Mathematically, it becomes equivalent to a problem on the Euclidean plane with a very simple formulation in Classical Mechanics: given a non-necessarily autonomous potent…
Tent adapts models during testing by minimizing entropy of predictions.
In a number of physically important cases, the nonholonomically (nonintegrable) constrained Ricci flows can be modelled by exact solutions of Einstein equations with nonhomogeneous (anisotropic) cosmological constants. We develop two geometric methods for constructing such solutions: The first approach applies the form…
Method adapts frozen models for few-shot tasks without training.
A generalized geometric method is developed for constructing exact solutions of gravitational field equations in Einstein theory and generalizations. First, we apply the formalism of nonholonomic frame deformations (formally considered for nonholonomic manifolds and Finsler spaces) when the gravitational field equation…
Framework reuses pre-trained models for data-free transfer learning.
Defines a new conformally invariant Yang-Mills type energy for 6-manifolds.
DAD++ improves test-time adversarial defense without access to training data.
