Authors: Yuxi Ma, Chi Zhang, Song-Chun Zhu
AI-generated Key Points
- Authors challenge the notion that Large Language Models (LLMs) represent artificial general intelligence
- LLMs excel at language processing but fall short of true general intelligence demonstrated by humans
- Importance of transparent evaluation methods for true generalization and concerns about data leakage from internet-trained models
- Proposal of the concept of unity of knowing and acting as crucial for artificial general intelligence, lacking in LLMs
- Emphasis on interactive environments with rich affordances to facilitate concept learning and knowledge acquisition beyond vision and language processing
- Call for meta-verse support for various reasoning tasks to enhance agent learning through interaction with objects
- Advocacy for development of a cognitive architecture integrating knowing and acting mechanisms for knowledge abstraction, accumulation, and application
- Stress on the need to focus on key challenges such as evaluation transparency, interactive environments, and unifying knowing and acting mechanisms to advance towards artificial general intelligence
Abstract: In this perspective paper, we first comprehensively review existing evaluations of Large Language Models (LLMs) using both standardized tests and ability-oriented benchmarks. We pinpoint several problems with current evaluation methods that tend to overstate the capabilities of LLMs. We then articulate what artificial general intelligence should encompass beyond the capabilities of LLMs. We propose four characteristics of generally intelligent agents: 1) they can perform unlimited tasks; 2) they can generate new tasks within a context; 3) they operate based on a value system that underpins task generation; and 4) they have a world model reflecting reality, which shapes their interaction with the world. Building on this viewpoint, we highlight the missing pieces in artificial general intelligence, that is, the unity of knowing and acting. We argue that active engagement with objects in the real world delivers more robust signals for forming conceptual representations. Additionally, knowledge acquisition isn't solely reliant on passive input but requires repeated trials and errors. We conclude by outlining promising future research directions in the field of artificial general intelligence.
