On the Limitations of the Elo, Real-World Games are Transitive, not Additive

AISTATS 2023poster

The Elo score has been extensively used to rank players by their skill or strength in competitive games such as chess, go, or StarCraft II. The Elo score implicitly assumes games have a strong additive—hence transitive—component. In this paper, we investigate the challenge of identifying transitive…

Decoupled Neural Interfaces using Synthetic Gradients

ICML 2017poster

Training directed neural networks typically requires forward-propagating data through a computation graph, followed by backpropagating error signal, to produce weight updates. All layers, or more generally, modules, of the network are therefore locked, in the sense that they must wait for the remain…

Reinforcement Learning with Unsupervised Auxiliary Tasks

ICLR 2017oral

Deep reinforcement learning agents have achieved state-of-the-art results by directly maximising cumulative reward. However, environments contain a much wider variety of possible training signals. In this paper, we introduce an agent that also maximises many other pseudo-reward functions simultaneou…

Understanding Synthetic Gradients and Decoupled Neural Interfaces

ICML 2017poster

When training neural networks, the use of Synthetic Gradients (SG) allows layers or modules to be trained without update locking – without waiting for a true error gradient to be backpropagated – resulting in Decoupled Neural Interfaces (DNIs). This unlocked ability of being able to update parts of…
