LLM Engineering and Memory Optimization

A novel approach to Retrieval Augmented Generation (RAG) uses a cascade of LLMs, starting with inexpensive local models and progressing to a hosted flagship, to improve enterprise document intelligence. This strategy focuses on both cost reduction and implementing a validation loop, with empirical testing of twenty local models against a top-tier hosted option. Separately, a new memory engine for AI agents addresses the limitation of context windows that prioritize recency over importance by implementing a usage-reinforced decay based on the Ebbinghaus forgetting curve.

AI in Scientific Discovery

A significant breakthrough in organ transplantation involves the successful transplantation of supercooled kidneys into pigs, a landmark achievement in preserving organs for longer periods. This development aims to overcome the critical time constraints currently faced in organ donation, where organs begin to deteriorate immediately after removal from the donor body.

Data Science Applications and User Experience

One data science scenario highlights the tension between financial incentives and user experience, illustrated by an overbooked flight situation where a potential $8 million gain was contrasted with a $5k payout and the risk of public backlash.
