Modern applications often struggle to scale, not because of weak infrastructure, but because decision-making intelligence is added only after systems are already under load. Auto-scaling, DevOps pipelines, and cloud elasticity help, but they are largely reactive by design. As user demand grows, engineering teams are forced to chase latency spikes, error rates, and infrastructure bottlenecks after they appear, turning scalability into a constant firefight. This is where AI-native solutions fundamentally change how scalability is engineered. By embedding intelligence directly into […]

Most AI apps send raw user input straight to OpenAI with zero filtering. I got tired of seeing it and built Sentinel Protocol, an open source local proxy with 81 security engines that scans every LLM request and response. It blocks PII, catches prompt injections, detects hallucinated URLs in model output, and handles MCP poisoning for AI agents. One command to start. Change one line in your SDK. 52,069 lines of code, 9 dependencies, MIT license. No cloud, […]

Public tension between Anthropic and the Pentagon may be strategic signaling, not separation. Ethical positioning protects reputation, while defense integration continues through controlled deployments and negotiation. Public perception, procurement leverage, and backchannel talks all shape how AI becomes embedded in national security infrastructure. Anthropic’s public ethical stance and Pentagon pressure likely reflect negotiation leverage, not disengagement. AI integration continues behind controlled federal deployments.

Cross-domain reinforcement learning (RL) aims to learn transferable policies under dynamics shifts between source and target domains. A key challenge lies in the lack of target-domain environment interaction and reward supervision, which prevents direct policy learning. To address this challenge, we propose Bridging Dynamics Gaps for Cross-Domain Reinforcement Learning (BDGxRL), a novel framework that leverages Diffusion Schrödinger Bridge (DSB) to align source transitions with target-domain dynamics encoded in offline demonstrations. Moreover, we introduce a reward modulation mechanism that […]

The more a thing tends to be permanent, the more it tends to be lifeless. Allan Watts Hey, listen. You’re not lazy. Let’s get that out of the way right now. Lazy people don’t lie awake at night, hearts pounding, staring at the ceiling while mentally screaming at themselves for not sending that email, not starting that proposal, not having that hard conversation. You do. I do. This is the special, advanced-class procrastination reserved for people who are […]

arXiv:2602.19964v2 Announce Type: replace-cross Abstract: Uncertainty quantification is central to safe and efficient deployments of deep learning models, yet many computationally practical methods lack lacking rigorous theoretical motivation. Random network distillation (RND) is a lightweight technique that measures novelty via prediction errors against a fixed random target. While empirically effective, it has remained unclear what uncertainties RND measures and how its estimates relate to other approaches, e.g. Bayesian inference or deep ensembles. This paper establishes these missing theoretical […]

arXiv:2602.08470v2 Announce Type: replace-cross Abstract: Credal predictors are models that are aware of epistemic uncertainty and produce a convex set of probabilistic predictions. They offer a principled way to quantify predictive epistemic uncertainty (EU) and have been shown to improve model robustness in various settings. However, most state-of-the-art methods mainly define EU as disagreement caused by random training initializations, which mostly reflects sensitivity to optimization randomness rather than uncertainty from deeper sources. To address this, we define EU […]

arXiv:2602.00834v3 Announce Type: replace-cross Abstract: Score-based methods are powerful across machine learning, but they face a paradox: theoretically path-independent, yet practically path-dependent. We resolve this by proving that practical training objectives differ from the ideal, ground-truth objective by a crucial, overlooked term: the path variance of the score function. We propose the MVP (**M**imum **V**ariance **P**ath) Principle to minimize this path variance. Our key contribution is deriving a closed-form expression for the variance, making optimization tractable. By parameterizing […]

arXiv:2510.15464v2 Announce Type: replace-cross Abstract: We study the problem of learning to generate an answer (or completion) to a question (or prompt), where there could be multiple correct answers, any one of which is acceptable at test time. Learning is based on demonstrations of some correct answer to each training question, as in Supervised Fine Tuning (SFT). We formalize the problem as imitation learning (i.e., apprenticeship learning) in contextual bandits, with offline demonstrations from some expert (optimal, or […]
