From Text to Knowledge: A Smarter Way to Classify Data

14.12.2025 by qfx

The pipeline transforms textual documents into a graph structure, initially extracting representations and defining relationships between nodes, then leverages a large language model to label a selection of these nodes before propagating those labels across the entire graph using a graph neural network.

A new approach combines the power of language models with graph networks to achieve accurate text classification, even when labeled data is limited.

Fast and Accurate Aerodynamic Prediction with Kernelized Neural Surrogates

14.12.2025 by qfx

For a range of airfoil geometries and angles of attack, a standalone neural network model demonstrably underpredicts the leading-edge suction peak; however, a multi-fidelity correction leveraging the KHRONOS framework partially recovers this peak and improves pressure recovery, bringing predictions closer to high-fidelity data and demonstrating an enhancement in accuracy for these specific aerodynamic conditions.

A new approach combines the strengths of kernel methods and neural networks to dramatically accelerate aerodynamic simulations while maintaining high accuracy.
