Rare Event Analysis of Large Language Models
Jake McAllister Dorman, Edward Gillman, Dominic C. Rose +2
Being probabilistic models, during inference large language models (LLMs) display rare events: behaviour that is far from typical but highly significant. By definition all rare eve…
Entanglement and localization in long-range quadratic Lindbladians
Alejandro Cros Carrillo de Albornoz, Dominic C. Rose, Arijeet Pal
Existence of Anderson localization is considered a manifestation of coherence of classical and quantum waves in disordered systems. Signatures of localization have been observed in…
Combining Reinforcement Learning and Tensor Networks, with an Application to Dynamical Large Deviations
Edward Gillman, Dominic C. Rose, Juan P. Garrahan
We present a framework to integrate tensor network (TN) methods with reinforcement learning (RL) for solving dynamical optimisation tasks. We consider the RL actor-critic method, a…
Training neural network ensembles via trajectory sampling
Jamie F. Mair, Dominic C. Rose, Juan P. Garrahan
In machine learning, there is renewed interest in neural network ensembles (NNEs), whereby predictions are obtained as an aggregate from a diverse set of smaller models, rather tha…
Random matrix theory for quantum and classical metastability in local Liouvillians
Jimin L. Li, Dominic C. Rose, Juan P. Garrahan +1
We consider the effects of strong dissipation in quantum systems with a notion of locality, which induces a hierarchy of many-body relaxation timescales as shown in [Phys. Rev. Let…
Reinforcement learning of rare diffusive dynamics
Avishek Das, Dominic C. Rose, Juan P. Garrahan +1
We present a method to probe rare molecular dynamics trajectories directly using reinforcement learning. We consider trajectories that are conditioned to transition between regions…
Hierarchical classical metastability in an open quantum East model
Dominic C. Rose, Katarzyna Macieszczak, Igor Lesanovsky +1
We study in detail an open quantum generalisation of a classical kinetically constrained model -- the East model -- known to exhibit slow glassy dynamics stemming from a complex hi…
Quantum jump Monte Carlo simplified: Abelian symmetries
Katarzyna Macieszczak, Dominic C. Rose
We consider Markovian dynamics of a finitely dimensional open quantum system featuring a weak unitary symmetry, i.e., when the action of a unitary symmetry on the space of density…
Theory of classical metastability in open quantum systems
Katarzyna Macieszczak, Dominic C. Rose, Igor Lesanovsky +1
We present a general theory of classical metastability in open quantum systems. Metastability is a consequence of a large separation in timescales in the dynamics, leading to the e…
A reinforcement learning approach to rare trajectory sampling
Dominic C. Rose, Jamie F. Mair, Juan P. Garrahan
Very often when studying non-equilibrium systems one is interested in analysing dynamical behaviour that occurs with very low probability, so called rare events. In practice, since…
A Tensor Network Approach to Finite Markov Decision Processes
Edward Gillman, Dominic C. Rose, Juan P. Garrahan
Tensor network (TN) techniques - often used in the context of quantum many-body physics - have shown promise as a tool for tackling machine learning (ML) problems. The application…
Spectral properties of simple classical and quantum reset processes
Dominic C. Rose, Hugo Touchette, Igor Lesanovsky +1
We study the spectral properties of classical and quantum Markovian processes that are reset at random times to a specific configuration or state with a reset rate that is independ…
Phase transitions in electron spin resonance under continuous microwave driving
Alexander Karabanov, Dominic C. Rose, Walter Köckenberger +2
We study an ensemble of strongly coupled electrons under continuous microwave irradiation interacting with a dissipative environment, a problem of relevance to the creation of high…
Metastability in an open quantum Ising model
Dominic C. Rose, Katarzyna Macieszczak, Igor Lesanovsky +1
We apply a recently developed theory for metastability in open quantum systems to a one-dimensional dissipative quantum Ising model. Earlier results suggest this model features eit…
