AI commentary
「This paper turns RAG from one-off isolated queries into a system that continuously accumulates experience, which is especially inspiring for teams working on knowledge-intensive and multi-hop QA. In real business, many questions are repetitive and interrelated; instead of retrieving from scratch every time, sinking verified reasoning into reusable assets may be key to cutting costs.」
Quick overview
LivingRAG introduces a writable and reusable experience store for graph-based retrieval-augmented generation (Graph RAG). It decomposes verified reasoning outcomes into graph signals and summaries: graph signals help retrieval locate entities and passages that were useful in earlier related queries, while summaries provide reference reasoning patterns for answer generation. Reusable signals are identified from shared entities, graph neighborhoods, and question templates in online QA streams. Experiments on multi-hop QA benchmarks show that LivingRAG improves accuracy over strong RAG baselines and reduces completion-token usage when relevant prior experience is reused.
- LivingRAG adds a writable experience store to a graph-based retrieval backbone, enabling reuse of reasoning experience in later queries.
- Experience is stored as graph signals and summaries, which aid retrieval and answer generation respectively.
- Reusable signals are extracted from shared entities, graph neighborhoods, and question templates to avoid redundant retrieval and reasoning.
- Experiments on multi-hop QA benchmarks show improved accuracy over strong RAG baselines and reduced completion-token usage.

Setoka：面向异构数据个性化Agent的层级用户理解基准
This paper is well worth attention, especially for researchers and engineers working on personalized agents, dialogue systems, and memory-augmented AI. It not only provides a benchmark but defines levels of user understanding from psychology, revealing systematic failures of current systems at higher levels. If you are designing memory-based agents, this paper reminds you that memory systems need to support cross-temporal, cross-source abstract reasoning, not just retrieval.

This paper is a must-read for anyone working on high-dimensional statistics, probabilistic modeling, and generative AI. It provides a simple yet powerful theoretical answer: sparsity can break the curse of dimensionality, and Bayesian networks offer a natural framework. Compared to black-box methods like VAEs and GANs, BAND is interpretable and provably convergent, especially valuable for industry needs like reliable confidence intervals. If you research time series forecasting or risk management, this paper may change how you approach high-dimensional density estimation.

FeaturedEquivariant Learning of a Transferable Three-Dimensional Classical Density Functional
等变学习可迁移的三维经典密度泛函
The most striking aspect of this paper is its direct coupling of machine learning to a core problem in statistical mechanics, using equivariant networks to learn a transferable density functional without any labels. For researchers in liquid physics or soft matter, this could be a new paradigm: do we need to run separate simulations for every new system anymore? For AI researchers, it also shows how to embed physical symmetries and variational principles into models rather than just fitting data. I recommend focusing on the methods, especially how equivariance and variational consistency are implemented—that's the real essence.
