Population-based Model Merging via Quality Diversity

This is the first in a series of blog posts presenting the results of Sakana AI’s research projects that were supported by the Japanese Ministry of Economy, Trade and Industry’s GENIAC supercomputing grant . Summary In evolutionary biology, an ecological niche refers to the relationship a species has with its environment determined by its unique abilities and characteristics. A specie’s niche encompasses the set of things that enables it to survive. These include specific skills and abilities that determine the prey it eats, the living space it occupies, etc. Generally, once occupied, a niche is typically highly resilient to invasion, making it challenging for other species to displace the incumbent species. The concept of an ecological niche can also be applied to AI agents. An AI agent’s niche is defined by its capabilities, the tasks it can perform, and the resources it consumes. A well-evolved agent can effectively occupy a specific niche, making it resilient to competition from other agents. This approach can enable a population of AI agents to emerge, each with specific capabilities that complement each other, collectively improving over time. …
