Bayesian Nonparametrics for Offline Skill Discovery
Valentin Villecroze, Harry J. Braviner, Panteha Naderian +2
Skills or low-level policies in reinforcement learning are temporally extended actions that can speed up learning and enable complex behaviours. Recent work in offline reinforcemen…
C-Learning: Horizon-Aware Cumulative Accessibility Estimation
Panteha Naderian, Gabriel Loaiza-Ganem, Harry J. Braviner +4
Multi-goal reaching is an important problem in reinforcement learning needed to achieve algorithmic generalization. Despite recent advances in this field, current algorithms suffer…
Nonlinear tides in a homogeneous rotating planet or star: global modes and elliptical instability
Adrian J. Barker, Harry J. Braviner, Gordon I. Ogilvie
We revisit the global modes and instabilities of homogeneous rotating ellipsoidal fluid masses, which are the simplest global models of rotationally and tidally deformed gaseous pl…
Tidal interactions of a Maclaurin spheroid. II: Resonant excitation of modes by a close, misaligned orbit
Harry J. Braviner, Gordon I. Ogilvie
We model a tidally forced star or giant planet as a Maclaurin spheroid, decomposing the motion into the normal modes found by Bryan (1889). We first describe the general prescripti…
Tidal interactions of a Maclaurin spheroid. I: Properties of free oscillation modes
Harry J. Braviner, Gordon I. Ogilvie
We review the work of Bryan (1889) on the normal modes of a Maclaurin spheroid, carrying out numerical calculations of the frequencies and spatial forms of these modes that have no…
Flows involving Lifshitz solutions
Harry Braviner, Ruth Gregory, Simon F. Ross
We construct gravity solutions describing renormalization group flows relating relativistic and non-relativistic conformal theories. We work both in a simple phenomenological theor…
