PaLM-E: A Revolutionary Model for AGI

Artificial General Intelligence (AGI) is an area of research that aims to develop AI systems capable of performing any intellectual task that a human being can do. In a remarkable breakthrough towards AGI, Google, Robotics, TU Berlin, and Google Research have developed a revolutionary multimodal AI model called PaLM-E. This model has the ability to comprehend and generate language, interpret images, and integrate both skills to execute complex commands for robots in the real world.

The development of PaLM-E involved merging Google's massive PaLM language model with the largest vision transformer neural network to date, known as ViT-22. This resulted in the creation of PaLM-E, which has an astounding 562 billion parameters. The secret behind PaLM-E's architecture lies in its embedding of Continual embodied observations from various sensor modalities into a pre-trained large language model's embedding space.

PaLM-E is designed to handle a broad range of visual and robotics tasks and has been demonstrated to control a robotic arm, arrange blocks, recognize individuals, and even explain the associated rules of traffic signs. The model's diverse training approach enables the transfer of skills from the vision language domains to be used for embodied decision making tasks, making robot planning more efficient. Additionally, the larger models of PaLM-E Show minimal drop-off in language skills, indicating that scaling out the model can prevent the problem of catastrophic forgetting.

The remarkable capabilities of PaLM-E, such as multimodal reasoning and the ability to reason across several images, demonstrate its potential as a generalist AI model. With further scaling, PaLM-E is expected to become even more generally intelligent, bringing us closer to the advent of AGI.

MimicPlay: Learning from Humans to Mimic Robotics Tasks

Another breakthrough in the field of AGI is MimicPlay, developed by NVIDIA and Stanford. MimicPlay is an imitation learning algorithm that can generalize when mimicking humans to complete robotics tasks just by watching. The algorithm utilizes two types of data sources: low-cost human play data and small-Scale teleoperated robot demonstration data.

MimicPlay achieves a performance improvement of over 50% in 14 challenging long horizon manipulation tasks compared to previous methods. It overcomes the challenge of learning complex tasks by just watching by utilizing human play data, which contains valuable information about physical interactions. The hierarchical learning framework of MimicPlay involves two stages: the high-level controller learns latent plans from human play data, and a pre-trained planner generates latent plans Based on the goal image sampled from the task video prompt.

The evaluations of MimicPlay in different long horizon manipulation tasks show that it significantly outperforms state-of-the-art imitation learning methods in task success rate, generalization ability, and robustness to disturbances. Even with just a small amount of multi-task teleoperated robot demonstrations, MimicPlay can generalize to new tasks with unseen temporal compositions in just 10 minutes of training.

MimicPlay's ability to learn from human demonstrations without the need for tedious programming opens up possibilities for humans to teach robots manipulation skills in the real world more efficiently.
