ViT-P: Rethinking Data-efficient Vision Transformers from Locality

Kavli Affiliate: Ran Wang | First 5 Authors: Bin Chen, Ran Wang, Di Ming, Xin Feng, | Summary: Recent advances of Transformers have brought new trust to computer vision tasks. However, on small dataset, Transformers is hard to train and has lower performance than convolutional neural networks. We make vision transformers as data-efficient as convolutional […]

Birth cluster simulations of planetary systems with multiple super-Earths: initial conditions for white dwarf pollution drivers

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Katja Stock, Dimitri Veras, Maxwell X. Cai, Rainer Spurzem, Simon Portegies Zwart | Summary: Previous investigations have revealed that eccentric super-Earths represent a class of planets which are particularly effective at transporting minor bodies towards white dwarfs and subsequently polluting their atmospheres with observable chemical signatures. However, […]

Cosmology and perturbations in tachyonic massive gravity

Kavli Affiliate: Lijing Shao | First 5 Authors: Amin Rezaei Akbarieh, Sobhan Kazempour, Lijing Shao, , | Summary: As massive gravity and its extensions offer physically well-defined gravitational theories with a nonzero graviton mass, we present a new extension of the de Rham-Gabadadze-Tolley (dRGT)massive gravity, which is tachyonic massive gravity theory. We firstly introduce the […]

From Images to Dark Matter: End-To-End Inference of Substructure From Hundreds of Strong Gravitational Lenses

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Sebastian Wagner-Carena, Jelle Aalbers, Simon Birrer, Ethan O. Nadler, Elise Darragh-Ford | Summary: Constraining the distribution of small-scale structure in our universe allows us to probe alternatives to the cold dark matter paradigm. Strong gravitational lensing offers a unique window into small dark matter halos ($<10^{10} […]
