Existing differentially private (DP) synthetic data generation mechanisms typically assume a single-source table. In practice, data is often distributed across multiple tables with relationships across tables. In this paper, we introduce the first-of-its-kind algorithm that can be combined with any existing DP mechanisms to generate synthetic relational databases. Our algorithm iteratively refine…

Building Faultline: A Reusable Chaos-Injection and Linearizability-Checking Harness Faultline is an open-source Go harness that injects faults into distributed systems, records every concurrent operation clients actually observed, and checks whether that history is linearizable — modeled on the methodology behind Kyle Kingsbury's Jepsen. Its reference target is a three-node etcd cluster; a second…

My GPS describes lanes like this: “Right lane” “Second lane from the left” “Middle lane” “Third lane from the right” Given a number of lanes and the index (from left) of a lane, compute the lane ...

Researcher Ka Heng Shiu explains how Alpha-Composited Block Coordinate Descent (ABCD) divides large radiance fields into manageable partitions while preserving full-scene context during training.

A log platform (Splunk, for example) meters ingest by the byte, and most bytes in a log line are repetitive text. Part of it is what the code prints: the words of a format string, identical every time that statement runs. The rest is added around the message: the level, the service and pod names, the fields a logging framework stamps on every line (in Java, the MDC). 10x runs as a sidecar to the …

Distinguishing between inputs containing precisely M ones versus M+Δ ones demands an unexpectedly high number of oracle checks. This work demonstrates a lower bound of Ω(max{ζ√((N-M)(M+Δ))/Δ, √(ζN/Δ)}), a measure of computational effort linked directly to input size and desired accuracy. The analysis tracks individual query progress using a novel multiplicative adversary method.

A final spacetime complexity of 1. 259 billion defines new performance in elliptic-curve point addition circuits. This result represents an 86.

The Greek letter β (beta) and the German letter ß (eszett) look similar, especially in some fonts. Now suppose an OCR program sees some character that could be a beta or could be an eszett. It could calculate some kind of distance between between the pixel pattern of the character and the pixel patterns of […] The post Bayesian OCR first appeared on John D. Cook .

Scientific Reports, Published online: 10 September 2026; doi:10.1038/s41598-026-70323-w Dispersion transition entropy: dual-modal feature fusion based on global attention mechanism for time series feature representation

---- @hhh4804 (As a physicist) i don't know, it feels like a chess player solving a position using a chess engine... i think we are completely missing the meaning of scientific research, there is no point in solving math problems using AI ---- Me Well it depends. Do you want to solve problems... Read more
