Log-Linear-Time Gaussian Processes Using Binary Tree Kernels

1 code implementation4 Oct 2022 Michael K. Cohen, Samuel Daulton, Michael A. Osborne

We present a new kernel that allows for Gaussian process regression in $O((n+m)\log(n+m))$ time.

Intelligence and Unambitiousness Using Algorithmic Information Theory

no code implementations13 May 2021 Michael K. Cohen, Badri Vellambi, Marcus Hutter

Algorithmic Information Theory has inspired intractable constructions of general intelligence (AGI), and undiscovered tractable approximations are likely feasible.

Fully General Online Imitation Learning

no code implementations17 Feb 2021 Michael K. Cohen, Marcus Hutter, Neel Nanda

If we run an imitator, we probably want events to unfold similarly to the way they would have if the demonstrator had been acting the whole time.

Pessimism About Unknown Unknowns Inspires Conservatism

no code implementations15 Jun 2020 Michael K. Cohen, Marcus Hutter

Our other main contribution is that the agent's policy's value approaches at least that of the mentor, while the probability of deferring to the mentor goes to 0.

Asymptotically Unambitious Artificial General Intelligence

no code implementations29 May 2019 Michael K. Cohen, Badri Vellambi, Marcus Hutter

General intelligence, the ability to solve arbitrary solvable problems, is supposed by many to be artificially constructible.

A Strongly Asymptotically Optimal Agent in General Environments

no code implementations4 Mar 2019 Michael K. Cohen, Elliot Catt, Marcus Hutter

This is known as strong asymptotic optimality, and it was previously unknown whether it was possible for a policy to be strongly asymptotically optimal in the class of all computable probabilistic environments.
