Neural Networks as Kernel Learners: The Silent Alignment Effect
Alexander Atanasov, Blake Bordelon, Cengiz Pehlevan
Neural networks in the lazy training regime converge to kernel machines. Can neural networks in the rich feature learning regime learn a kernel machine with a data-dependent kernel…
Conformal Block Expansion in Celestial CFT
Alexander Atanasov, Walker Melton, Ana-Maria Raclariu +1
The 4D 4-point scattering amplitude of massless scalars via a massive exchange is expressed in a basis of conformal primary particle wavefunctions. This celestial amplitude is expa…
Scattering and the Celestial Torus
Alexander Atanasov, Adam Ball, Walker Melton +2
Analytic continuation from Minkowski space to split signature spacetime has proven to be a powerful tool for the study of scattering amplitudes. Here we show that, under th…
