Radim Marek: pg_stat_statements: everything it can't
Part one made the core case: pg_stat_statements counts, it doesn't record. It walked through how the queryid jumble fragments one logical query into many rows, how the first-seen text freezes your per-request tags, and how the averages bury the p99 that actually pages you. All of that was about data the extension has and distorts. This part is about the rest: the entries it silently throws away, the query text that can vanish all at once, the plans and replicas it never records, and the knobs...

Laurenz Albe: When is a function leakproof?
© Laurenz Albe 2026 Instigated by a customer, I've been trying to improve the performance of row-level security. Central to good performance in this area is the concept of leakproof functions and operators. I'll go over the priciples quickly, but I'll focus on the question what leakproof really means, and what it should mean. In a way, this article is a request for comments: I'd be curious what you think about the topic! Security barrier views and row-level security PostgreSQL has two relate...

Spectral Asymptotics of Neural Network Loss Landscapes: An Exact Decomposition of the Curvature Exponent
arXiv:2606.02596v1 Announce Type: new Abstract: The curvature exponent $\alpha$ in $h_k \propto \sigma_k^\alpha$ -- governing how Hessian eigenvalues scale with gradient singular values -- varies systematically across layer types ($\alpha \approx 2$ for convolutions, $\approx 1$ for transformer attention, $< 1$ for MLP up-projections). Why? We prove the Spectral Alignment Decomposition: $\alpha = 2 + d\log\Phi_k / d\log\sigma_k$, where $\Phi_k$ measures alignment between Kronecker factor eig...

Human-in-the-Loop Contextual Bandits for Short-Term Rental Dynamic Pricing: Structural Equivalence of Historical Warm-Up and Approval-Gated Live Learning
arXiv:2606.02595v1 Announce Type: new Abstract: Dynamic pricing in short-term rental (STR) markets presents a distinctive challenge for online learning algorithms: pricing decisions carry significant financial risk, operators require explainability, and market feedback is sparse (one booking outcome per listed night). We introduce the Human-in-the-Loop Gated Bandit (HITL-GB) framework, in which a contextual bandit algorithm generates price recommendations but a human agent retains authority ...

Lean-GAP: A Dataset of Formalized Graduate Algebra Problems
arXiv:2606.02588v1 Announce Type: new Abstract: We present Lean-GAP (Lean-Graduate Agebra Problems), 430 formalized graduate-level algebra problems from the textbook Abstract Algebra by Dummit and Foote. We develop a scalable pipeline consisting of PDF-to-LaTeX preprocessing, autoformalization into Lean 4, and verification of informal-formal correspondence. While the preprocessing and autoformalization stages can be largely automated, we find that verification remains the most subtle and lab...

Fewer, Better Frames: A Compute-Normalized Proof of Concept for Coherence-First World-Model Rendering with Model-Guided FSR4 Frame Generation
arXiv:2606.02586v1 Announce Type: new Abstract: World models are often evaluated by native frame cadence, but higher nominal frame rate can trade away long-horizon scene stability. This article reports an independent proof of concept implemented using Overworld's Waypoint-1.5 family and WorldEngine runtime on a Windows fallback stack with ONNX Runtime + DirectML and an FSR4 DX12 bridge. The tested coherence-first branch generates higher-context anchor frames at a 15 FPS presentation-timeline...

An improved PINN framework integrating localized collocation scheme and PIKF
arXiv:2606.02585v1 Announce Type: new Abstract: We propose a localized physics-informed kernel function neural network (LPIKFNN), which is an improved physics-informed neural network (PINN) based on physics-informed kernel function (PIKF). In the LPIKFNN framework, the localized collocation scheme discretizes the physical quantities within the local domain, where the physical field is represented as a linear combination of PIKFs. Based on this representation, the multilayer perceptron is tra...

IdiomX A Multilingual Benchmark for Idiom Understanding, Retrieval, and Interpretation
arXiv:2606.02584v1 Announce Type: new Abstract: Idiomatic expressions remain a persistent challenge for natural language processing because their meanings are often non-compositional, context-dependent, and difficult to align across languages. Existing idiom resources are often limited in scale, contextual diversity, or multilingual coverage, restricting their utility for modern language models. We introduce IdiomX, a large-scale multilingual benchmark for idiom understanding, retrieval, and...

A complete simulation framework for stone degradation on 3D real geometries
arXiv:2606.02583v1 Announce Type: new Abstract: We present a complete workflow for predicting stone degradation phenomena, such as marble sulfation, in works of art. The main challenge is to accurately acquire the geometry of the artwork and then use it to perform simulations based on a mathematical model of the degradation process, typically formulated as a system of partial differential equations (PDEs). To address this, we generate a point cloud of the object surface using photogrammetr...

Cost-Aware Query Routing in RAG: Empirical Analysis of Retrieval Depth Tradeoffs
arXiv:2606.02581v1 Announce Type: new Abstract: Retrieval-augmented generation (RAG) faces a fundamental three-way tension: deeper retrieval improves factual grounding but inflates token costs and end-to-end latency. Static retrieval configurations cannot resolve this tension across heterogeneous query workloads -- simple definitional queries waste budget on unnecessary context, while complex analytical prompts are underserved by shallow retrieval. This paper introduces \emph{Cost-Aware RAG}...

We use Apache Cassandra 4.x as the underlying storage for these main reasons:Throughput, latency, and cost: Cassandra can handle millions of low‑latency reads and writes in a cost-effective manner.Operational maturity: Our data platform team has deep operational...

Radim Marek: pg_stat_statements: everything it tells you
If not first, pg_stat_statements is one of the most used extensions in the PostgreSQL ecosystem. It ships in contrib and costs almost nothing to use. Most of us turn to it to answer the question: what is the database actually doing? It's genuinely useful. You can use it to get a snapshot of what happened in a given timeframe, and make a faster decision about what to fix. Coming from other database engines, you might reach for it expecting something a bit more, a query store. The built-in feat...
