Universal Approximation Under Constraints is Possible with Transformers
[article]
2022
arXiv
pre-print
Our results imply the first universal approximation theorem for classical transformers with exact convex constraint satisfaction. ...
The result guarantees that given an objective function L, a constraint set K, and a family of soft constraint sets, there is a probabilistic transformer F̂ that approximately minimizes L and whose outputs ...

Discrete R symmetries and anomalies
2014
Journal of High Energy Physics
We review the Green-Schwarz cancellation of discrete anomalies, providing a heuristic explanation why, in the heterotic string, only the "model-independent dilaton" transforms non-linearly under discrete ...
symmetries; this argument suggests that, in other theories, multiple fields might play a role in anomaly cancellations, further weakening any anomaly constraints at low energies. ...
It is perfectly possible that the axion-like fields a i cancel various non-universal anomalies while precision gauge unification is achieved with 1/g 2 i ∼ s 0 . ...

Constraints on the universal contact interaction

Constraints from LEP2 imply that this universal contact interaction cannot be the origin of the recently observed high-Q^2 events at HERA. ...
If these new forces are independent of colour and flavour quantum numbers including baryon and lepton number, then all low energy constraints, arising from quark-lepton universality, flavour-changing neutral ...

On Constraint Problems with Incomplete or Erroneous Data
[chapter]
2002
Lecture Notes in Computer Science
Real-world constraint problems abound with uncertainty. ...
We define the certainty closure to an uncertain constraint problem and show how it can be derived by transformation to an equivalent certain problem. ...
The framework is complementary to stochastic data models (e.g. [6] ). Our current research looks at finding uncertain constraint classes and their corresponding tractable transformation operators. ...

However, if there are any first-class constraints, then the group of transformations contains an invariant subgroup, those transformations having a vanishing generator. ...

Application of the no-signaling principle to obtain quantum cloners for any allowed value of fidelity
2013
Physical Review A. Atomic, Molecular, and Optical Physics
Using only the no-signaling principle and an assumption about the form of the Schmidt decomposition, we show that for "any" allowed fidelity there is a "unique" approximate qubit cloner which can be written ...
We introduce the prime cloners whose fidelities have multiplicative property and show that the fidelity of the prime cloners for the infinite copy limit is 1/2. ...

In this work, the problem is instead approximated by a deterministic one, through the unscented transform (UT), and its conjugate extension (CUT). ...
The conventional way to find an approximate solution to the extended problem is through Monte Carlo (MC) methods, resulting in high computational cost. ...
It is well-known that any Gaussian can be transformed into one with zero expectation and unitary covariance, through an affine transformation. ...
