从“内部世界”到虚拟造物：世界模型的前世今生

Core Viewpoint - The article discusses the significant advancements brought by Google's DeepMind with the release of Genie 3, which showcases a new path towards Artificial General Intelligence (AGI) through the concept of "World Models" [4][5][6]. Group 1: Introduction of Genie 3 - On August 5, Google DeepMind launched Genie 3, a model capable of generating interactive 3D virtual environments based on user prompts, demonstrating enhanced real-time interaction capabilities compared to previous AI models [5]. - Genie 3 features a "Promptable World Events" function, allowing users to dynamically alter the generated environment through text commands, showcasing its advanced interactivity [5]. Group 2: Concept of World Models - World Models are inspired by the human brain's ability to create and utilize an "inner world" to simulate future scenarios, which is crucial for decision-making and action [8][9]. - The development of World Models has evolved from early attempts to mimic human cognitive functions to more sophisticated models that can predict and simulate real-world dynamics [10][11]. Group 3: Technical Implementation of World Models - The implementation of World Models involves several key stages: Representation Learning, Dynamic Modelling, Control and Planning, and Result Output, each contributing to the AI's ability to understand and interact with the world [15][16][17][18]. - Representation Learning allows AI to compress external data into an internal language, while Dynamic Modelling enables the simulation of future scenarios based on actions taken [15][16]. Group 4: Applications of World Models - World Models can significantly enhance "embodied intelligence," allowing AI agents to learn through simulated experiences in a safe environment, reducing costs and risks associated with real-world trials [20][21]. - In the realm of digital twins, World Models can create proactive simulations that predict changes and optimize processes in real-time, enhancing automation and decision-making [21][22]. - The education and research sectors can benefit from World Models by creating virtual laboratories for precise predictions and interactive learning environments [22]. Group 5: Potential and Challenges of World Models - While World Models present vast potential for various applications, they also raise ethical and governance concerns, such as the blurring of lines between reality and virtuality, and the potential for behavioral manipulation [24][25][26]. - The debate surrounding World Models as a pathway to AGI highlights differing opinions within the AI community, with some experts advocating for their necessity while others question their effectiveness compared to model-free approaches [28][29][30].
