Abstract

We introduce Voyager, the first LLM-powered embodied lifelong learning agent in Minecraft that continuously explores the world, acquires diverse skills, and makes novel discoveries without human intervention. Voyager consists of three key components: 1) an automatic curriculum that maximizes exploration, 2) an ever-growing skill library of executable code for storing and retrieving complex behaviors, and 3) a new iterative prompting mechanism that incorporates environment feedback, execution errors, and self-verification for program improvement. Voyager interacts with GPT-4 via blackbox queries, which bypasses the need for model parameter fine-tuning. The skills developed by Voyager are temporally extended, interpretable, and compositional, which compounds the agent's abilities rapidly and alleviates catastrophic forgetting. Empirically, Voyager shows strong in-context lifelong learning capability and exhibits exceptional proficiency in playing Minecraft. It obtains 3.3x more unique items, travels 2.3x longer distances, and unlocks key tech tree milestones up to 15.3x faster than prior SOTA. Voyager is able to utilize the learned skill library in a new Minecraft world to solve novel tasks from scratch, while other techniques struggle to generalize.

Voyager discovers new Minecraft items and skills continually by self-driven exploration, significantly outperforming the baselines.

Introduction

Building generally capable embodied agents that continuously explore, plan, and develop new skills in open-ended worlds is a grand challenge for the AI community. Classical approaches employ reinforcement learning (RL) and imitation learning that operate on primitive actions, which could be challenging for systematic exploration, interpretability, and generalization. Recent advances in large language model (LLM) based agents harness the world knowledge encapsulated in pre-trained LLMs to generate consistent action plans or executable policies. They are applied to embodied tasks like games and robotics, as well as NLP tasks without embodiment. However, these agents are not lifelong learners that can progressively acquire, update, accumulate, and transfer knowledge over extended time spans.

Let us consider Minecraft as an example. Unlike most other games studied in AI, Minecraft does not impose a predefined end goal or a fixed storyline but rather provides a unique playground with endless possibilities. An effective lifelong learning agent should have similar capabilities as human players: (1) propose suitable tasks based on its current skill level and world state, e.g., learn to harvest sand and cactus before iron if it finds itself in a desert rather than a forest; (2) refine skills based on environment feedback and commit mastered skills to memory for future reuse in similar situations (e.g. fighting zombies is similar to fighting spiders); (3) continually explore the world and seek out new tasks in a self-driven manner.

Using the wrist or arm to create sharp, detached notes without stiffening.

The enemy of any pianist is unnecessary muscle tension. Sándor taught that muscles should only be active at the exact moment of tone production. They must relax immediately afterward. 3. The Use of Weight

Let's explore the core principles of Sándor's approach, why his teachings remain vital today, and how to find the best resources for his work. Who Was György Sándor?

Sándor’s ultimate legacy is his ability to bridge the gap between mechanical execution and artistic expression. The Core Philosophy of "On Piano Playing"

Moving the forearm like turning a doorknob to facilitate tremolos and trills. 2. Eliminating Tension

Sándor’s book revolutionized piano pedagogy by applying physical laws and human anatomy to the keyboard. He argued that playing the piano should never cause pain. If it does, the pianist's mechanics are wrong. 1. The Five Basic Technical Patterns

Using gravity to produce a rich, resonant tone without muscle tension.

György Sándor (1912–2005) was a world-renowned concert pianist and pedagogue.

György Sándor, the legendary Hungarian pianist and student of Béla Bartók, remains one of the most influential figures in 20th-century piano pedagogy. His seminal book, On Piano Playing: Motion, Sound, and Expression , is universally regarded as a masterpiece of piano technique. Decades after its initial publication in 1981, pianists still search for the "György Sándor on piano playing pdf updated" to refine their technique and prevent injury.

He studied under Béla Bartók and Zoltán Kodály at the Liszt Academy in Budapest.
