AI & ML Research

LLM Memory and Optimization

Engineers are exploring novel approaches to enhance LLM memory and optimize search functionalities. One method for vector search by comparing on-disk and in-memory Approximate Nearest Neighbor (ANN) indexes like HNSW, SPANN, and Disk ANN. Separately, a system for AI agents, moving beyond simply retaining the newest information to prioritizing what matters, inspired by the Ebbinghaus forgetting curve. For Retrieval Augmented Generation (RAG) systems, developers are identifying that many perceived hallucinations are actually extraction errors, proposing to improve accuracy. Additionally, a cascaded LLM approach that scales up to a hosted flagship, incorporating a validation loop to manage costs and improve enterprise document intelligence.

Foundation Models and Simulation

A new class of foundation models, dubbed "Tabular LLMs," with zero-shot capabilities, outperforming tuned gradient-boosted trees on the Tab Arena benchmark. In a departure from traditional physics simulation, researchers without solving fluid equations, utilizing the Lattice Boltzmann Method derived from first principles and implemented in C++. These advancements highlight a growing trend towards more efficient and versatile AI models across different data modalities.

Real-World Applications and Lessons Learned

Progress is being made in the critical field of organ transplantation, with into pigs in a landmark achievement, potentially extending the viability of donor organs significantly. This research is part of a broader effort to to combat organ shortages. On the infrastructure side, a guide outlines how to in the cloud for automating PII extraction from emails. Reflecting on years of experience, one engineer shared eight and a half years of ML lessons, emphasizing patience, optimism, discipline, project execution, and teamwork. Another piece delves into the, illustrated by the scenario of an overbooked flight.
