Reinitializing weights vs units for maintaining plasticity in neural networks
Loss of plasticity is a phenomenon in which a neural network loses its ability to learn when trained for an extended time on non-stationary data. It is a crucial problem to overcome when designing systems that learn continually. An effective technique for preventing loss of plasticity is reinitializing parts of the network. In this paper, we compare two different reinitialization schemes: reinitializing units vs reinitializing weights. We propose a new algorithm, which we name \textit{selective…

At this point it's just a matter of time until credulous people begin worshipping AI stochastic parrots as gods.

Quantum light and radiation in Rindler spacetime: from uncertainty relations to the cosmological implications
Based on an analogy between diffraction integral formalism of classical field propagation and Feynman path integral approach to quantum field theory, we develop a quantum model for light and radiation in Rindler spacetime. The framework helps to reveal acceleration-induced contributions to the traditional Heisenberg position-momentum uncertainty relation. A modified Planck energy density distribution of radiation is established and reveals equivalence between temperature and Rindler acceleratio…

Notes on Rindler wave packets in Minkowski spacetime
We consider wave packets of a massless scalar field that have well-localized Rindler energy, and examine how their energy appears to a Minkowski observer to see how the classical gravitational blue-shift formula is modified quantum mechanically. We derive, by using the saddle point approximation, an analytic expression for the Minkowski momentum distribution of such Rindler wave packets. We find a universal lower bound on the uncertainty of Minkowski momentum; the momentum distribution can neve…

I'm rewatching The West Wing (reassuring in these dark times to watch a COMPETANT if fictional, administration).
Those guys would obsess over the PERCEPTION of what color tie the president wore in a stump speech or what FONT was used for a notice about national parks. CJ uses one word vs. another and the press goes bananas.
Remember Obama's tan suit?
THIS administration slings unreviewed, unvetted, zero effort AI slop like its nothing and noone bats an eye.

I have been traveling through Greece with a rental car last week, really recommended, mixing little villages along the coastline with classic landmarks like Delphi and Epidaurus. Also low prices compared with the Netherlands.

What emerged was not a diverse network of activists, but a concentrated ecosystem built to serve the firm at its center:
Mothership Strategies.
After subtracting these massive operational costs—the payments to Mothership, the fees for texting services, the cost of digital ads and list rentals—the final sum delivered to candidates and committees is vanishingly small. My analysis of the network's FEC disbursements reveals that, at most, $11 million of the $678 million raised fr…

Dark Matter in an Evanescent Three-Brane Randall-Sundrum Scenario
Apart from its gravitational interactions, dark matter (DM) has remained so far elusive in laboratory searches. One possible explanation is that the relevant interactions to explain its relic abundance are mainly gravitational. In this work we consider an extradimensional Randall-Sundrum scenario with a TeV-PeV IR brane, where the Standard Model is located, and a GeV-TeV deep IR (DIR) one, where the DM lies. When the curvatures of the bulk to the left and right of the IR brane are very similar,…

Also ich empfehle die Aktien von Rückversicherern. MunichRE und Hannover RE insbesondere.
Das klingt jetzt ein wenig absurd mit all den Versicherungsfällen wie die Feuer in Kalifornien und Unwetterschäden allerorten, die ja eher zunehmen werden.
Das schlägt ja voll in die Bilanzen durch.
Nur wissen nach jedem dieser Ereignis immer mehr Leute, dass sie eine Versicherung brauchen … Preis bald egal.
Man muss ja nicht gleich Rheinmetall kaufen.
