Revisiting non-Gaussianity from non-attractor inflation models [PDF]
, 2017 Non-attractor inflation is known as the only single field inflationary scenario that can violate non-Gaussianity consistency relation with the Bunch-Davies vacuum state and generate large local non-Gaussianity.

Topology, 1976 neighborhood U satisfying X = f~ f”U. We will study the real homology of hyperbolic n=0 expanding attractors (defined below in the appendix) using the branched manifolds of [S] and dynamical properties of [l] and [71. One can assume that X is connected and in an appropriate sense oriented (expanding attractors are locally homeomorphic to Euclidean ...

Physical Review D, 2009 We apply the entropy formalism to the study of the near-horizon geometry of extremal black p-brane intersections in D>5 dimensional supergravities. The scalar flow towards the horizon is described in terms an effective potential given by the superposition of the kinetic energies of all the forms under which the brane is charged.

Attractor as a convex combination of a set of attractors
Communications in Nonlinear Science and Numerical Simulation, 2021 Abstract This paper presents an effective approach to constructing numerical attractors of a general class of continuous homogenous dynamical systems: decomposing an attractor as a convex combination of a set of other existing attractors. For this purpose, the convergent Parameter Switching (PS) numerical method is used to integrate the underlying ...

New Mathematics and Natural Computation, 2009 This paper summarizes our recent attempts to integrate action and perception within a single optimization framework. We start with a statistical formulation of Helmholtz's ideas about neural energy to furnish a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts.

Speaker-Independent Speech Separation With Deep Attractor Network [PDF]
IEEE/ACM Transactions on Audio Speech and Language Processing, 2017 Despite the recent success of deep learning for many speech processing tasks, single-microphone, speaker-independent speech separation remains challenging for two main reasons.

Fortschritte der Physik, 2008 AbstractWe review recent results in the study of attractor horizon geometries (with non‐vanishing Bekenstein‐Hawking entropy) of dyonic extremal d = 4 black holes in supergravity. We focus on 𝒩 = 2, d = 4 ungauged supergravity coupled to a number nVof Abelian vector multiplets, outlining the fundamentals of the special Kähler geometry of the vector ...
