Activation Relaxation: A Local Dynamical Approximation to Backpropagation in the Brain

1 code implementation11 Sep 2020 Beren Millidge, Alexander Tschantz, Anil. K. Seth, Christopher L. Buckley

The backpropagation of error algorithm (backprop) has been instrumental in the recent success of deep learning.

On the Relationship Between Active Inference and Control as Inference

no code implementations23 Jun 2020 Beren Millidge, Alexander Tschantz, Anil. K. Seth, Christopher L. Buckley

Active Inference (AIF) is an emerging framework in the brain sciences which suggests that biological agents act to minimise a variational bound on model evidence.

Reinforcement Learning as Iterative and Amortised Inference

no code implementations13 Jun 2020 Beren Millidge, Alexander Tschantz, Anil. K. Seth, Christopher L. Buckley

There are several ways to categorise reinforcement learning (RL) algorithms, such as either model-based or model-free, policy-based or planning-based, on-policy or off-policy, and online or offline.

Reconciling emergences: An information-theoretic approach to identify causal emergence in multivariate data

1 code implementation17 Apr 2020 Fernando E. Rosas, Pedro A. M. Mediano, Henrik J. Jensen, Anil. K. Seth, Adam B. Barrett, Robin L. Carhart-Harris, Daniel Bor

The broad concept of emergence is instrumental in various of the most challenging open scientific questions -- yet, few quantitative theories of what constitutes emergent phenomena have been proposed.

Reinforcement Learning through Active Inference

no code implementations28 Feb 2020 Alexander Tschantz, Beren Millidge, Anil. K. Seth, Christopher L. Buckley

The central tenet of reinforcement learning (RL) is that agents seek to maximize the sum of cumulative rewards.

Scaling active inference

no code implementations24 Nov 2019 Alexander Tschantz, Manuel Baltieri, Anil. K. Seth, Christopher L. Buckley

In reinforcement learning (RL), agents often operate in partially observed and uncertain environments.

Beyond integrated information: A taxonomy of information dynamics phenomena

1 code implementation5 Sep 2019 Pedro A. M. Mediano, Fernando Rosas, Robin L. Carhart-Harris, Anil. K. Seth, Adam B. Barrett

Most information dynamics and statistical causal analysis frameworks rely on the common intuition that causal interactions are intrinsically pairwise -- every 'cause' variable has an associated 'effect' variable, so that a 'causal arrow' can be drawn between them.
