AI Memory Processing

A cross-disciplinary research team has uncovered that AI models, especially the Transformer, exhibit memory processing methods that are remarkably similar to the human brain’s hippocampus. This significant development indicates that integrating neuroscience concepts, such as those involving the NMDA receptor, into AI could enhance its memory capabilities, thereby propelling the AI domain forward and offering deeper insights into the functioning of the human brain.

The research team found that the way AI consolidates memory is akin to the processes observed in the human hippocampus. This discovery could lead to advancements in AI technology and enrich our understanding of how human memory works.

Researchers from the Center for Cognition and Sociality and the Data Science Group at the Institute for Basic Science (IBS) have identified a remarkable parallel between how AI models and the human hippocampus process memory. This insight offers a fresh perspective on the transformation of short-term memories into long-term ones in AI systems.

Advancing AI by Studying Human Intelligence

The pursuit of Artificial General Intelligence (AGI), spearheaded by prominent organizations like OpenAI and Google DeepMind, has placed a premium on emulating human-like intelligence. A key component in this advancement is the Transformer model [Figure 1], whose fundamental principles are now being examined in greater depth.

Applying Brain Learning Mechanisms to AI

The secret to developing sophisticated AI systems lies in understanding how they learn and store information. The research team applied concepts of memory consolidation, particularly through the NMDA receptor in the hippocampus, to AI models.

The NMDA receptor serves as a crucial component in the brain, facilitating learning and memory formation. It functions like a selective gate, allowing substances into the cell under certain conditions, which is critical for memory creation and retention. The specific role of the magnesium ion in this process is of particular interest.

AI Models Emulating Brain Functions

The team observed that the Transformer model uses a gatekeeping mechanism resembling the brain’s NMDA receptor [refer to Figure 1]. This finding prompted an exploration into whether the Transformer’s memory consolidation could be influenced by a mechanism analogous to the NMDA receptor’s gating process.

In the animal brain, low magnesium levels are associated with reduced memory function. The researchers observed that simulating the NMDA receptor’s operation in the Transformer enhanced its long-term memory capabilities. This mimics the brain’s mechanism where varying magnesium levels influence memory strength. This groundbreaking discovery proposes that AI model learning processes can be elucidated using established neuroscience principles.

Expert Perspectives on AI and Neuroscience

C. Justin LEE, a neuroscientist director at the institute, stated, “This study represents a significant step in advancing both AI and neuroscience. It enables a deeper exploration of the brain’s operational mechanisms and the development of more sophisticated AI systems based on these insights.”

CHA Meeyoung, a data scientist in the team and at KAIST, remarked, “The human brain operates remarkably efficiently compared to the resource-intensive large AI models. Our research paves the way for developing cost-effective, high-performance AI systems that learn and remember in a human-like manner.”

Integrating Cognitive Processes with AI Design

This research stands out for its initiative in integrating brain-inspired nonlinearity into AI structures, marking a notable progression in simulating human-like memory processes. The fusion of human cognitive processes with AI design promises not only the creation of cost-effective, high-performance AI systems but also offers valuable insights into brain function through AI model studies.
