Adaptive Hard-Soft Physics-Informed Neural Networks for Robust Boundary-Constrained PDE Solving

This study proposes a unified hard--soft physics--informed neural network (HSPINN) with adaptive loss weighting to address the slow convergence and inaccurate boundary enforcement of conventional PINNs. The framework enforces Dirichlet and periodic boundary conditions exactly through analytical lifting or masking, while treating PDE residuals and initial conditions as soft constraints balanced by an inverse-share softmax strategy.

Rethinking Molecular Graph Backdoors under Chemistry-aware Admission

The article introduces ChemGuard, an operational protocol that formalizes the overlooked admission stage of molecular learning pipelines by requiring sanitizable strings and consistent graph reconstruction. This framework reveals that many existing graph-based backdoors lose efficacy because their poisons are chemically invalid or representation-inconsistent.

Litmus: Zero-Label, Code-Driven Metric Specification for Evaluating AI Systems

Litmus is a zero-label system that designs evaluation and monitoring metrics for AI pipelines by eliciting evaluation intent from source code and targeted interrogation. Instead of assuming the evaluation target is known, it identifies what must be measured and why to construct a justified metric portfolio.

LFM2.5 230M Runs In-Browser at 1,400 tok/s via Custom WebGPU Kernels

The LiquidAI LFM2.5-230M model is now running locally in the browser using custom WebGPU kernels. These specialized kernels were originally developed by Fable 5 prior to its shutdown and Opus 4.8. The demonstration was recorded on an M4 Max device, achieving a generation speed of 1,400 tokens per second. All processing occurs entirely within the user's browser environment without external server dependencies. A GGUF version of the model is available for download on Hugging Face alongside the standard checkpoint. Users can interact with the live demo hosted by the webml-community on Hugging Face Spaces.
