How Do You Actually Test an AI System? A Layered Strategy From Five Tools I Built
18+ min ago (500+ words) Every engineer who has shipped an LLM feature eventually hits the same wall. Your unit tests are green. Nothing throws. And yet the thing is quietly, obviously worse than it was last week. Someone swapped a model, someone tweaked a…...

OpenAI maths bombshell sparks debate about who gets credit in age of AI
19+ min ago (701+ words) Mathematicians give credit for insights gleaned through discussion but AI tools are not set up to do this. Credit: Hill Street Studios/Getty The widespread use of AI models across most fields of research, and the difficulty of tracing the…...

Applied Sciences, Vol. 16, Pages 9223: VMD-Assisted DGCM-Net: A Dual-Representation Cross-Interaction Network with Multi-SNR Training for Transformer Core Looseness Diagnosis
37+ min ago (391+ words) Vibration-based diagnosis can identify transformer core looseness non-intrusively, but subtle vibration differences and noise-disturbed Gramian angular field (GAF) textures reduce diagnostic accuracy at low signal-to-noise ratios (SNRs). This paper proposes a variational mode decomposition (VMD)-assisted dual-representation cross-interaction network (DGCM-Net) with…...
Your Agent Burns LLM Money on Switch Statements. Jev Claims 444x Less
1+ hour, 2+ min ago (1025+ words) In TypeSafe's own evals, Jev ties Claude Sonnet 5 at 67.8% for about 1/294th the cost per case. Move your agent's decisions off the LLM, in TypeScript. Tagged with ai, agents, typescript, llm....
Applied Sciences, Vol. 16, Pages 9218: An Improved DeepLabV3+ Network for Bare Rock Segmentation in Remote Sensing Images
1+ hour, 5+ min ago (616+ words) To improve the binary semantic segmentation of bare rock and background in complex urban environments, this study developed an improved DeepLabV3+ model for red–green–blue (RGB) imagery derived from Gaofen-1 (GF-1) data. Four backbone networks—Xception, ResNet50, MobileNetV2, and MobileNetV3—were first evaluated....
Applied Sciences, Vol. 16, Pages 9222: Evidence-Weighted Multi-Criteria Decision Support for Subjective Quality Assessment Under Sparse and Unbalanced Information
1+ hour, 17+ min ago (439+ words) Decision making for complex products often depends on subjective user experience, while competing alternatives may be supported by strongly unequal numbers of observations. This study develops an evidence-weighted multi-criteria decision-making methodology for such sparse and unbalanced information. A seven-category rating…...
RoboTech Frontier Hub founder explains why AI needs blockchain based verification
1+ hour, 33+ min ago (1558+ words) In an interview with crypto.news, Selva Ozelli speaks with RoboTech Frontier Hub founder Denis “Dan” Saklakov about the intersection of artificial intelligence, blockchain and finance, and how his AI assisted investment tool Meijin uses an investor’s risk profile to…...
Applied Sciences, Vol. 16, Pages 9217: Extrapolation-Aware Gaussian Process Configuration for Small-Sample Complex-Equipment Cost Estimation
1+ hour, 41+ min ago (423+ words) Complex-equipment cost estimation often relies on very small historical datasets, and new targets may fall partly outside the feature ranges represented by those data. This study examines whether two observable data-state indicators can provide a transparent basis for configuring Gaussian…...
