Recursively Summarizing Books with Human Feedback

no code implementations22 Sep 2021 Jeff Wu, Long Ouyang, Daniel M. Ziegler, Nisan Stiennon, Ryan Lowe, Jan Leike, Paul Christiano

Our human labelers are able to supervise and evaluate the models quickly, despite not having read the entire books themselves.

Abstractive Text Summarization Question Answering

Learning to summarize from human feedback

1 code implementation2 Sep 2020 Nisan Stiennon, Long Ouyang, Jeff Wu, Daniel M. Ziegler, Ryan Lowe, Chelsea Voss, Alec Radford, Dario Amodei, Paul Christiano

We collect a large, high-quality dataset of human comparisons between summaries, train a model to predict the human-preferred summary, and use that model as a reward function to fine-tune a summarization policy using reinforcement learning.

Fine-Tuning Language Models from Human Preferences

3 code implementations18 Sep 2019 Daniel M. Ziegler, Nisan Stiennon, Jeffrey Wu, Tom B. Brown, Alec Radford, Dario Amodei, Paul Christiano, Geoffrey Irving

Most work on reward learning has used simulated environments, but complex information about values is often expressed in natural language, and we believe reward learning for language is a key to making RL practical and safe for real-world tasks.

Language Modelling

Supervising strong learners by amplifying weak experts

3 code implementations19 Oct 2018 Paul Christiano, Buck Shlegeris, Dario Amodei

Many real world learning tasks involve complex or hard-to-specify objectives, and using an easier-to-specify proxy can lead to poor performance or misaligned behavior.

Unrestricted Adversarial Examples

1 code implementation22 Sep 2018 Tom B. Brown, Nicholas Carlini, Chiyuan Zhang, Catherine Olsson, Paul Christiano, Ian Goodfellow

We introduce a two-player contest for evaluating the safety and robustness of machine learning systems, with a large prize pool.

AI safety via debate

1 code implementation2 May 2018 Geoffrey Irving, Paul Christiano, Dario Amodei

To make AI systems broadly useful for challenging real-world tasks, we need them to learn complex human goals and preferences.

Deep reinforcement learning from human preferences

6 code implementations NeurIPS 2017 Paul Christiano, Jan Leike, Tom B. Brown, Miljan Martic, Shane Legg, Dario Amodei

For sophisticated reinforcement learning (RL) systems to interact usefully with real-world environments, we need to communicate complex goals to these systems.

Atari Games

A Connection between Generative Adversarial Networks, Inverse Reinforcement Learning, and Energy-Based Models

3 code implementations11 Nov 2016 Chelsea Finn, Paul Christiano, Pieter Abbeel, Sergey Levine

In particular, we demonstrate an equivalence between a sample-based algorithm for maximum entropy IRL and a GAN in which the generator's density can be evaluated and is provided as an additional input to the discriminator.

Imitation Learning

Concrete Problems in AI Safety

1 code implementation21 Jun 2016 Dario Amodei, Chris Olah, Jacob Steinhardt, Paul Christiano, John Schulman, Dan Mané

Rapid progress in machine learning and artificial intelligence (AI) has brought increasing attention to the potential impacts of AI technologies on society.

Webb, Matthew Willson, Kelvin Xu, Lijun Xue, Li Yao, Saizheng Zhang, Ying Zhang

Since its introduction, it has been one of the most used CPU and GPU mathematical compilers - especially in the machine learning community - and has shown steady performance improvements.
