arXiv:2307.03587v3 Announce Type: replace-cross Abstract: We study non-stationary linear contextual bandits through the lens of sequential Bayesian inference. Whereas existing algorithms typically rely on the Weighted Regularized Least-Squares (WRLS) objective, we study Weighted Sequential Bayesian (WSB), which maintains a posterior…
arXiv:2510.01969v1 Announce Type: cross Abstract: We consider adversarially robust classification in a multiclass setting under arbitrary loss functions and derive dual and barycentric reformulations of the corresponding learner-agnostic robust risk minimization problem. We provide explicit characterizations for important cases such…
arXiv:2410.14054v4 Announce Type: replace-cross Abstract: Recent studies have shown that many nonconvex machine learning problems satisfy a generalized-smooth condition that extends beyond traditional smooth nonconvex optimization. However, the existing algorithms are not fully adapted to such generalized-smooth nonconvex geometry and…
arXiv:2510.02056v1 Announce Type: cross Abstract: Normalising-flow variational inference (VI) can approximate complex posteriors, yet single-flow models often behave inconsistently across qualitatively different distributions. We propose Adaptive Mixture Flow Variational Inference (AMF-VI), a heterogeneous mixture of complementary flows (MAF, RealNVP, RBIG)…
Apple has removed the “Waze but for ICE sightings” app ICEBlock from its App Store, as reported previously by Business Insider. A post from its developer relayed Apple’s App Review message about the ban, saying, “We just received a message…
“Radical Left” and “Democrat Senators” come in for attack.
On Thursday afternoon, after agreeing to a short extension while they continued negotiations, NBCUniversal and YouTube announced a new carriage deal to keep the network’s channels live on the streaming TV service. If the process sounds familiar, it’s because the…
IBM just released Granite 4.0, an open-source LLM family that swaps monolithic Transformers for a hybrid Mamba-2/Transformer stack to cut serving memory while keeping quality. Sizes span a 3B dense “Micro,” a 3B hybrid “H-Micro,” a 7B hybrid MoE “H-Tiny”…
“We fully intend to recover the New Glenn first stage on this next launch.”
In this post, we demonstrate how organizations can enhance their employee productivity by integrating Kore.ai’s AI for Work platform with Amazon Q Business. We show how to configure AI for Work as a data accessor for Amazon Q index for…
