AI Infers a Simulated Universe’s History From Today’s Matter
Preprint reports close agreement in simplified simulations, but says the trained network is not ready for real data.
AI controller keeps GSM8K accuracy near full budget with far less reasoning
Preprint: AERA came close to a 128-response baseline on an untouched 300-question GSM8K test while using 4.44 responses per question, though broader gains remain uncertain.
BERT leads test of sector-aware cyber threat intelligence routing
Preprint: The study reports that BERT scored best overall on a custom MISPPriv dataset of 872 events, but its averages covered only 10 of 11 sectors.
Streaming solver reports 7% Massart and 32% oblivious noise bounds
An arXiv preprint describes theoretical convergence guarantees for a streaming method using fresh measurements under two corruption models.
Preprint method tracks artery motion better in 4D heart scans
Tests favored a coronary-mask-guided method on artery-motion measures, but the preprint says it cannot reliably capture valve motion and may distort nearby structures when the artery shifts sharply.
openJiuwen posts higher scores than selected systems on two coding tests
An arXiv preprint reports 87.19% on Terminal-Bench 2.1 and 82.6% on SWE-bench Verified, but the comparisons do not isolate the harness alone.
Graph study sets limits on forbidden zero-forcing patterns
Preprint finds a finite boundary for minimal forbidden graphs and classifies several families with a complementary zero-forcing parameter of at most 3.
Tuned Lattice Model Offers Clues to a Possible Continuum Limit
Preprint simulations find stable low-lying mass ratios, but the evidence does not yet establish a continuum theory.
Model finds photon counting can nearly match quantum limit in magnetometry
Preprint: In an idealized three-level system, measuring a single photon's frequency added magnetic-field information beyond recording whether it was lost.
Model ties South Korea's education race to smaller families
Preprint analysis finds a modeled fertility gain from capacity-preserving lotteries, but the result depends on assumptions about education and destination value.
AI framework recovers C from binaries, but behavior still slips
Preprint: Chisel used compiler and fuzzing feedback in an iterative loop, while stripped binaries and higher optimization levels had weaker reported results.
AI training method reports gains on harder mathematics problems
Preprint researchers report higher benchmark scores after giving extra weight to correct answers on difficult prompts, with important limits on the evidence.
AI agents that adapt teamwork report higher reasoning scores
Preprint: A multi-agent system retrieved evidence before generating its workflow and reported 78.68% average accuracy across seven benchmarks.
Analysis Says Tree Search and Monte Carlo Control Share a Core
An arXiv preprint argues that Monte Carlo Tree Search and every-visit Monte Carlo control share a sampling and updating mechanism within a defined conceptual scope.
New Preprint Simplifies Analysis of a Randomized Integration Method
The theoretical study links the method's expected error to a Haar-based measure of smoothed-out variation, while leaving its practical performance untested.
A model combining speech and gaze better predicts turn-taking
A version-one arXiv preprint reports stronger held-out performance when speech intensity, gaze and interpersonal closeness are combined in controlled four-person conversations.
Preprint: Compact latent hubs lead four recommendation tasks
A Kuaishou recruitment preprint reports the best AUC on four ranking tasks and a 5.48% improvement in resume-submission conversion, with key test details missing.
AI Control Room Test Tracks Commands, Replays and Agent Moves
Preprint: A 15-run software evaluation linked operator commands to replay evidence and portable artifacts, but did not test people or social behavior.
Preprint reports lower errors from projected gausslets
A computational study found its biggest gains in compact basis tests of the hydrogen molecular ion, H2 and restricted C2, with smaller differences at higher order.
