Deep dives
Unsupervised and reinforcement learning in robotics
The combination of unsupervised learning and reinforcement learning in robotics is a key focus of this podcast episode. The speaker discusses how unsupervised learning, which involves training neural networks on text data to predict the next word, can be used to enhance reinforcement learning in robotics. By integrating unsupervised learning into the training process, robots can acquire general reasoning abilities and acquire skills from their own experience, making them more adaptable and efficient in the real world. This approach has shown promising results in bridging the gap between simulation and real-world robotic applications.
Generalizable reasoning in pre-trained language models
The podcast episode explores the concept of pre-trained language models, specifically transformers, and their ability to perform general reasoning across different domains. The speaker presents a study that investigates the transferability of pre-trained language models to various tasks, such as image classification, protein sequence prediction, and logical operations. Surprisingly, the pre-trained language models, when combined with simple linear layers and task-specific fine-tuning, demonstrate surprisingly good performance on these diverse tasks, indicating that they have internalized more general reasoning capabilities beyond just language processing. This line of research suggests the potential for creating unified representations and reasoning engines that can be applied to multiple modalities and domains.
Opportunities in multi-modal learning
The podcast episode highlights the potential of multi-modal learning, where models are trained on multiple data modalities simultaneously. The discussion explores the benefits of combining different sources of information, such as text and images, to learn unified representations that can enhance performance across various tasks. This approach has shown promise in fields like natural language processing and robotics, where different modalities, such as text, images, and videos, can be leveraged together to improve understanding and reasoning capabilities. The speaker suggests that further research in this area can lead to more powerful and adaptable AI systems.
The Robot Brains podcast
During the episode, the guest mentions his own podcast called The Robot Brains. The podcast focuses on bridging the gap between AI research and real-world applications, with a particular emphasis on bringing AI into practical robotics. The podcast features discussions with guests who share insights and experiences in deploying AI technologies in real-world scenarios. The Robot Brains podcast can be found on popular podcast platforms such as Spotify and Apple Podcasts.

It explores how unsupervised learning can enhance reinforcement learning by enabling robots to acquire general reasoning abilities and acquire skills through their own experiences. The episode also highlights the transferability of pre-trained language models to perform well on diverse tasks beyond their specific domain. Additionally, it discusses the potential of multi-modal learning and the benefits of training models on multiple data modalities simultaneously. The episode concludes by mentioning a podcast called The Robot Brains, which focuses on the practical applications of AI in robotics.
Today we’re joined by Pieter Abbeel, a Professor at UC Berkeley, co-Director of the Berkeley AI Research Lab (BAIR), as well as Co-founder and Chief Scientist at Covariant.
In our conversation with Pieter, we cover a ton of ground, starting with the specific goals and tasks of his work at Covariant, the shift in needs for industrial AI application and robots, if his experience solving real-world problems has changed his opinion on end to end deep learning, and the scope for the three problem domains of the models he’s building.
We also explore his recent work at the intersection of unsupervised and reinforcement learning, goal-directed RL, his recent paper “Pretrained Transformers as Universal Computation Engines” and where that research thread is headed, and of course, his new podcast Robot Brains, which you can find on all streaming platforms today!
