Active multi-fidelity surrogate modeling is developed for multi-condition airfoil shape optimization to reduce high-fidelity CFD cost while retaining RANS-level accuracy. The framework couples a low-fidelity-informed Gaussian process regression transfer model with uncertainty-triggered sampling and a synchronized elitism rule embedded in a hybrid genetic algorithm. Low-fidelity XFOIL evaluations provide inexpensive features, while sparse RANS simulations are adaptively allocated when predictive uncertainty exceeds a threshold; elite candidates are mandatorily validated at high fidelity, and the population is re-evaluated to prevent […]

compression-aware intelligence suggests the real problem isn’t just hallucinations, it’s instability under variation. a model can give a correct answer once but if small changes in phrasing cause it to resolve that underlying tension differently, you get contradictions. that’s the signal that the compression hasn’t actually reconciled the underlying patterns. instead of “is this answer correct?” the new question becomes: “does this answer stay consistent when the same meaning is expressed differently?” using compression tension score (CTS) submitted […]

A central question in the LLM debate is whether transformers can infer rules absent from training, or whether apparent generalisation reduces to similarity-based interpolation over observed examples. We test a strong interpolation-only hypothesis in two controlled settings: one where interpolation is ruled out by construction and proof, and one where success requires emitting intermediate symbolic derivations rather than only final answers. In Experiment 1, we use a cellular automaton with a pure XOR transition rule and remove specific […]

I have been trying to install isaaclab on windows for the past few days and i always end up with the same error everytime. conflicting packages while installing and dll load error while running import h5py i followed pip installation https://isaac-sim.github.io/IsaacLab/main/source/setup/installation/pip_installation.html here i installed recommended nvidia driver, installed vc tools C++ dev, added long path, but still end up with the same error over and over again. Please help while executing pip install “isaacsim[all,extscache]==5.1.0” –extra-index-url https://pypi.nvidia.com ERROR: pip’s […]

Federated Learning (FL) is increasingly applied in sectors like healthcare, finance, and IoT, enabling collaborative model training while safeguarding user privacy. However, FL systems are susceptible to Byzantine adversaries that inject malicious updates, which can severely compromise global model performance. Existing defenses tend to focus on specific attack types and fail against untargeted strategies, such as multi-label flipping or combinations of noise and backdoor patterns. To overcome these limitations, we propose FedAOT-a novel defense mechanism that counters multi-label […]

Stochastic resetting, where a dynamical process is intermittently returned to a fixed reference state, has emerged as a powerful mechanism for optimizing first-passage properties. Existing theory largely treats static, non-learning processes. Here we ask how stochastic resetting interacts with reinforcement learning, where the underlying dynamics adapt through experience. In tabular grid environments, we find that resetting accelerates policy convergence even when it does not reduce the search time of a purely diffusive agent, indicating a novel mechanism beyond […]
