PiDR: Physics-Informed Inertial Dead Reckoning for Autonomous Platforms

Researchers propose PiDR, a physics-informed neural network framework for autonomous navigation using only inertial sensors, achieving 29% positioning improvement over conventional approaches. The system addresses critical limitations of traditional deep learning by embedding physical principles directly into the model, enabling accurate dead reckoning in GPS-denied environments without requiring extensive training data.

Adaptive Data Harvesting for Efficient Neural Network Learning with Universal Constraints

Researchers propose an adaptive data harvesting approach using reinforcement learning to dynamically select training samples for neural networks constrained by universal conditions. The method improves upon fixed heuristics for training Lyapunov Neural Networks and Physics-Informed Neural Networks, demonstrating faster convergence and better solution quality across test problems.

Geometric Kolmogorov--Arnold Network (GeoKAN)

Researchers introduce Geometric Kolmogorov-Arnold Networks (GeoKANs), an advancement in KAN-type neural networks that learn geometry-adapted coordinate systems rather than relying on fixed Euclidean inputs. By adapting a diagonal Riemannian metric during training, GeoKAN redistributes computational capacity toward regions of rapid variation, making it particularly effective for physics-informed learning and differential equation problems.

Bifurcation Models: Learning Set-Valued Solution Maps with Weight-Tied Dynamics

Researchers present bifurcation models, a machine learning approach that uses weight-tied dynamical systems to learn multiple valid solutions for problems with set-valued outputs. Rather than forcing a single target label, the model represents an attractor landscape where different initializations converge to different stable equilibria, enabling discovery of diverse valid solutions without explicit branch labels.

Accelerated and data-efficient flow prediction in stirred tanks via physics-informed learning

Researchers demonstrate that physics-informed machine learning can predict fluid flows in industrial stirred tanks with significantly less training data than purely data-driven approaches. The study reveals diminishing returns in accuracy beyond moderate dataset sizes, with physics-based constraints proving most valuable in low-data regimes.
