Show HN: AI memory with biological decay (52% recall) (github.com)

A new AI memory system named YourMemory has been introduced, designed to enhance AI assistants' capacity for persistent memory, mimicking human memory with a focus on biological decay. Unlike conventional AI systems that reset their knowledge after each session, YourMemory retains important information while allowing less significant data to fade. This innovative framework utilizes a combination of methods, including BM25 and vector representation, achieving a recall rate of 59% in multi-session conversations—significantly outperforming alternatives like Zep Cloud, which recorded only 28%. This advancement is crucial for the AI/ML community as it addresses a fundamental limitation in interactive AI systems by enabling them to dynamically adjust and evolve their knowledge base over time. The implementation is straightforward, requiring minimal setup and supporting various programming environments, which broadens accessibility for developers. Key features include a two-round retrieval process, facilitating contextually relevant memory recall, and automatic decay mechanisms that manage memory lifecycle effectively. Overall, YourMemory represents a significant stride in creating AI systems that not only learn but remember and utilize past interactions to provide a more engaging user experience.
