Can AI Weather Models Weather the Storm? Testing Forecast Resilience

08.12.2025 by qfx

Despite the inherent uncertainty introduced by increasingly substantial Gaussian noise applied to initial conditions-ranging from 0% to 50%-the FCNv2 model consistently predicted the trajectory of Hurricane Florence (September 13-17, 2018), with each prediction representing the median cumulative positional error across thirty independent simulations, demonstrating a remarkable robustness even as real-world conditions inevitably deviate from perfect data.

A new study assesses the robustness of NVIDIA’s FourCastNetv2 AI model when predicting Hurricane Florence, finding generally reliable track forecasts even with imperfect data.

The Hidden Geometry of Neural Networks

07.12.2025 by qfx

Despite variations in architecture, data, and training objectives, deep neural networks-including Mistral-7B LoRAs, Vision Transformers, and LLaMA-8B models-consistently exhibit a shared, low-dimensional representational subspace within their weight matrices, evidenced by rapid spectral decay and suggesting the potential for compression into a universal model trained with lightweight coefficient tuning, though this convergence also prompts questions regarding the recovery of a truly representative subspace and the limitations it may impose on model diversity.

New research reveals that deep learning models consistently operate within surprisingly constrained spaces, offering pathways to more efficient AI.
