Learning to Play General-Sum Games against Multiple Boundedly Rational Agents

AAAI 2023technical

We study the problem of training a principal in a multi-agent general-sum game using reinforcement learning (RL). Learning a robust principal policy requires anticipating the worst possible strategic responses of other agents, which is generally NP-hard. However, we show that no-regret dynamics can…

MosaicBERT: A Bidirectional Encoder Optimized for Fast Pretraining

NeurIPS 2023poster

Although BERT-style encoder models are heavily used in NLP research, many researchers do not pretrain their own BERTs from scratch due to the high cost of training. In the past half-decade since BERT first rose to prominence, many advances have been made with other transformer architectures and trai…
