Beyond Softmax: A New Perspective on Gradient Bandits

Kavli Affiliate: David Muller | First 5 Authors: Emerson Melo, Emerson Melo, , , | Summary: We establish a link between a class of discrete choice models and the theory of online learning and multi-armed bandits. Our contributions are: (i) sublinear regret bounds for a broad algorithmic family, encompassing Exp3 as a special case; (ii) […]

Heterochromatin-based silencing of a foreign tandem repeat in Drosophila melanogaster shows unusual biochemistry and temperature sensitivity

Kavli Affiliate: Elena Gracheva | Authors: Tingting Gu, Elena Gracheva, Michael Lee, Wilson Leung, Sophia Bieser, Alixandria Nielsen, Adam T. Smiley, Nhi N.T. Vuong, Matthias Walther, Gunter Reuter, Sarah C.R. Elgin and Andrew M Arsham | Summary: Eukaryotic genomes are packaged into chromatin, a regulatory nucleoprotein assembly. Establishment, maintenance, and interconversion of chromatin states is […]

DRAGON-III simulation: modelling million-body globular and nuclear star clusters

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Kai Wu, Kai Wu, , , | Summary: As a continuation of DRAGON-II, we present the DRAGON-III project, which focuses on the simulations of million-body globular clusters and nuclear clusters over 10 Gyr. We report on its preliminary results on globular clusters. The first 100 Myr of […]

Reduction of the impact of the local valley splitting on the coherence of conveyor-belt spin shuttling in $^28$Si/SiGe

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Mats Volmer, Mats Volmer, , , | Summary: Silicon quantum chips offer a promising path toward scalable, fault-tolerant quantum computing, with the potential to host millions of qubits. However, scaling up dense quantum-dot arrays and enabling qubit interconnections through shuttling are hindered by uncontrolled lateral variations of […]
