Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Jeroen Homan, Joe Bright, Sara E. Motta, Diego Altamirano, Zaven Arzoumanian | Summary: We present Neutron Star Interior Composition Explorer X-ray and Arcminute Microkelvin Imager Large Array radio observations of a rapid hard-to-soft state transition in the black hole X-ray transient MAXI J1820+070. During the transition […]
Kavli Affiliate: Peter Ford | First 5 Authors: Cédric Colas, Tristan Karch, Nicolas Lair, Jean-Michel Dussoux, Clément Moulin-Frier | Summary: Developmental machine learning studies how artificial agents can model the way children learn open-ended repertoires of skills. Such agents need to create and represent goals, select which ones to pursue and learn to achieve them. […]
Kavli Affiliate: Peter Ford | Summary:Developmental machine learning studies how artificial agents can model the way children learn open-ended repertoires of skills. Such agents need to create and represent goals, select which ones to pursue and learn to achieve them. Recent approaches have considered goal spaces that were either fixed and hand-defined or learned using […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Emanuele Castorina, Simon Foreman, Dionysios Karagiannis, Adrian Liu, Kiyoshi W. Masui | Summary: The Packed Ultra-wideband Mapping Array (PUMA) is a proposed low-resolution transit interferometric radio telescope operating over the frequency range 200 – 1100MHz. Its rich science portfolio will include measuring structure in the universe […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Dacheng Lin, Jay Strader, Aaron J. Romanowsky, Jimmy A. Irwin, Olivier Godet | Summary: We recently discovered the X-ray/optical outbursting source 3XMM J215022.4-055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mass of a few tens of […]
Kavli Affiliate: Rainer Weiss | Summary:The detection of gravitational waves from compact binary mergers by LIGO has opened the era of gravitational wave astronomy, revealing a previously hidden side of the cosmos. To maximize the reach of the existing LIGO observatory facilities, we have designed a new instrument that will have 5 times the range […]
Kavli Affiliate: Peter Ford | Summary:People are becoming increasingly comfortable using Digital Assistants (DAs) to interact with services or connected objects. However, for non-programming users, the available possibilities for customizing their DA are limited and do not include the possibility of teaching the assistant new tasks. To make the most of the potential of DAs, […]
Kavli Affiliate: Peter Ford | Summary:Autonomous reinforcement learning agents, like children, do not have access to predefined goals and reward functions. They must discover potential goals, learn their own reward functions and engage in their own learning trajectory. Children, however, benefit from exposure to language, helping to organize and mediate their thought. We propose LE2 […]
Kavli Affiliate: Herman Marshall | First 5 Authors: Paolo Soffitta, Niccolò Bucciantini, Eugene Churazov, Enrico Costa, Michal Dovciak | Summary: Since the birth of X-ray Astronomy, spectacular advances have been seen in the imaging, spectroscopic and timing studies of the hot and violent X-ray Universe, and further leaps forward are expected in the future. On […]
Kavli Affiliate: John D. Richardson | First 5 Authors: Jamie S. Rankin, David J. McComas, John D. Richardson, Nathan A. Schwadron, | Summary: In mid-2012, a GMIR observed by Voyager 2 crossed through the heliosheath and collided with the heliopause, generating a pressure pulse that propagated into the very local interstellar medium. The effects of […]
