Democratizing LLM Training with the Edge: Challenges, Systems, and the Road Ahead

arXiv:2610.32215v1 Announce Type: new Abstract: The growing computational power of modern GPU data centers has let a few industrial giants train and deploy large language models (LLMs) on massive amounts of data. Yet the sheer scale of these models and their training data makes centralized development increasingly hard to sustain, and at the same time shuts out smaller institutions that hold relevant private data but lack comparable infrastructure. In this paper, we organize our positions on distributed LLM training around the pretraining and fine-tuning paradigms, covering federated learning, split learning, and decentralized approaches, and we assess their readiness for geo-distributed settings with heterogeneous hardware and unreliable connectivity. We then present a {\em unified} syste

X-Dubbing: Speech-to-Speech Translation under Temporal and Visual Constraints

arXiv:2610.32042v1 Announce Type: new Abstract: Cross-lingual dubbing aims to convert source speech into target-language speech that remains synchronized with the original video. The key to this task is to produce a faithful translation that is naturally speakable within the source timing, which is non-trivial because languages differ in duration, rhythm, and articulation. In this paper, we propose X-Dubbing, which formulates the task as a joint problem of time-aware speech-to-text translation and video-aware text-to-speech. Specifically, our method consists of a Dubbing Translator that generates temporally structured scripts and a Voice Actor that renders them in synchrony with the source video, both grounded in a language-agnostic timing budget. We further refine the translator with dubb

Research reveals that activation interventions struggle to achieve conditional reuse in tool usage models.

The paper was posted on arXiv on October 26, 2026 (ID 2610.31686), and, based on the Qwen3.5-27B model, it systematically examined the impact of activation interventions on “conditional reuse” capabilities in tool-use tasks that depend on temporal or permission-based eligibility assessments. The experiments showed that while the intervention significantly improved the accuracy of target selection, it failed to generalize in scenarios involving fact‑based and identifier‑recombination tasks, and it did not enhance independent judgments of candidate eligibility.

Why it mattersThis study is the first to clearly distinguish among three types of capabilities—“goal-selection control,” “condition-sensitive judgment,” and “complete-action correctness”—and demonstrates that merely optimizing output answers is insufficient to ensure that a model truly understands and reuses the conditions set by an intervention (such as time or permissions), thereby offering methodological implications for trustworthy tool invocation and the design of controllable AI systems.

Quantum Cadence: Post-Quantum Consensus with Multiple Concurrent Proposers

arXiv:2610.32803v1 Announce Type: new Abstract: The consensus protocols of most high-performance blockchains use quorum certificates, which bundle the signatures of a quorum of validators. Signature schemes such as BLS can aggregate the signatures of a whole quorum into a single short signature, which keeps these certificates small. A large-scale quantum computer would break these schemes, and no post-quantum scheme with comparable aggregate size and aggregation time is known. Without aggregation, a certificate holds one large post-quantum signature per member of the quorum, so it becomes infeasible for each validator to broadcast certificates, as modern consensus protocols often require. We present Quantum Cadence, a post-quantum consensus protocol with multiple concurrent proposers that

New research reveals serious measurement bias in LLM-based math tutoring assessments: exact-match scoring underestimates effectiveness by nearly 40 percentage points.

The paper “MisconceptDialogue: Evaluation Criteria Shape Measured Success in LLM Math Tutoring,” published on arXiv on October 26, 2026, introduces the MISCONCEPTDIALOGUE automated evaluation framework, which assesses the performance of five open-source small-parameter LLMs (7B–14B) as math tutoring models through over 5,000 rounds of dialogue. The study finds that the mainstream exact-match scoring method achieves only a 42.1% remediation success rate, whereas an expert‑calibrated LLM referee evaluates the same dialogues at 81.3%, a gap of 39.2 percentage points; moreover, this discrepancy is not accidental—four types of LLM referees show high agreement with 200 human‑annotated results, with a maximum kappa coefficient of 0.91. In addition, the models exhibit virtually no differentiation in their responses to diagnostic information (correct or incorrect concepts), indicating their limited ability to effectively leverage such diagnostic inputs.

Why it mattersThis study directly addresses the core flaw in current methodologies for evaluating LLM-based educational applications: reliance on a single, rigid automated scoring system can severely distort assessments of actual competence. Its large-scale simulation experiments, multi-rater convergence validation, and empirical analysis of the breakdown in diagnostic–instructional coupling provide critical warnings and a replicable methodological benchmark for standardizing AI-driven educational assessment.

The study proposes the “Schema Consistency Index” (SCI) to assess the coherence of belief representations in language models.

On October 26, 2026, arXiv published the paper arXiv:2610.31683v1, introducing the Schema Coherence Inventory (SCI)—a 96-item forced-choice scale designed to assess whether the beliefs attributed to persona-conditioned language models genuinely structure their cognition, rather than merely eliciting emotional responses.

Why it mattersThis study fills the current gap in the lack of a verifiable measurement method for the “degree of belief internalization” in language models; through validation by clinical experts, testing across multiple model backbones, and the design of target-specific criteria, it provides the first assessment framework that focuses on cognitive structures rather than emotional representations, and has open-sourced all its tools.

Mining Frames: Association Rule Mining as an Unsupervised Framework for News Framing Detection

arXiv:2610.31874v1 Announce Type: new Abstract: Computational framing analysis is dominated by supervised classifiers that require large annotated corpora and predefined frame taxonomies, limiting their use for non-English languages, novel events, and low-resource settings. This paper presents Association Rule Mining (ARM) as an unsupervised, annotation-free framework for news framing detection. Each document or sentence is treated as a transaction of lexical items, and high-lift co-occurrence rules are read as candidate framing signals (Gamson and Modigliani's condensing symbols), confirmed in context by journalist-researchers. The primary validation is Framing Gaza: 25,512 English-language articles from 16 US, UK, French, and German outlets covering the first year of the Gaza war (Octobe

PPO vs. SAC: A Comparative Study for Cooperative Motion Control of Dual-Arm Space Robots

arXiv:2610.32034v1 Announce Type: new Abstract: The growing population of orbital debris has intensified interest in active debris removal and on-orbit servicing, for which dual-arm space manipulators offer improved grasping stability and load distribution relative to single-arm systems. However, coordinating two manipulators under inter-arm collision avoidance, orientation alignment, and sensing uncertainty remains challenging. This paper develops a coordinated reinforcement learning framework for cooperative motion planning of a dual-arm space manipulator in a target-reaching task with inter-arm collision-avoidance constraints. A centralized state representation combines joint-space, end-effector, and target-relative information, while a multi-objective reward function promotes target-re

Autoregressive Multimodal Anomaly Detection with Large Language Models for Microservice Systems

arXiv:2610.31722v1 Announce Type: new Abstract: Microservice systems have become a dominant architecture for large-scale cloud applications, enabling rapid deployment and elastic scaling. However, ensuring the reliability and availability of microservice systems critically relies on effective anomaly detection, as failures and performance anomalies can quickly propagate across services and severely impact end-to-end system behavior. Existing multimodal anomaly detection approaches for microservice systems often struggle with two fundamental limitations: (i) the neglect of modality-specific characteristics in favor of cross-modality fusion, and (ii) the "identity-shortcut" problem that affects the feature reconstruction process. To address these issues, we propose LLMMAD, an autoregressive

PnP*: A certifiable solver for Perspective-n-Point

arXiv:2610.31797v1 Announce Type: new Abstract: Estimating a camera pose from 3D-2D correspondences - Perspective-n-Point - is one of the most fundamental problems in computer vision. Existing methods either solve a minimal problem or replace the objective with an easier one. Surprisingly, no scalable certifiable solver for the actual Maximum Likelihood Estimation (MLE) exists. We propose PnP*, the first practical solver that guarantees efficient computation and returns a certifiable globally optimal solution. We prove that the underlying convex relaxation is exact under moderate noise, which to our knowledge is the first stability guarantee for any relaxation for the MLE of PnP. Furthermore, we reduce the relaxation by exploiting chordal sparsity pattern and quotient ring reduction such t

AudioLift: Audio-Driven Single Image to Full-Head Gaussian Avatar via Multi-view Video Generation

arXiv:2610.31747v1 Announce Type: new Abstract: Existing 3D talking avatar methods mainly rely on parametric face models including 3DMM or FLAME, whose compact motion representations limit their ability to synthesize extreme expressions and to model accessories such as headwear. We introduce AudioLift, a two-stage framework that uses generated multi-view videos as the intermediate representation for audio-driven avatar generation without parametric face models or per-instance optimization. Our framework combines a synchronized multi-view video generation stage with an inconsistency-robust Gaussian reconstruction stage to recover coherent full-head geometry from a single portrait image. Extensive experiments demonstrate that AudioLift produces 3D talking avatars capable of capturing more ex

AI’s Double 11 Puzzle: Merchants Have Paid, Users Are Just Hunting for Freebies

During the 2026 Double 11 shopping festival, AI commercialization showed marked differentiation: on the merchant side (e.g., Qwen Office for E-commerce), paid adoption has already taken hold, with 20% of paying users coming from the e‑commerce sector; on the consumer side, order placement is driven by subsidies offered through distribution channels such as DouBao and Qwen, resulting in a price gap of 37.5%, yet user trust remains low (only 16.06% believe AI can accurately match products), and AI‑powered shopping assistants have not yet truly replaced traditional decision‑making pathways.

Why it mattersThe material is based on an in-depth report published by Titanium Media on October 26, 2026, which systematically reviews three categories of AI applications during Double 11: ① AI-powered shopping assistance penetrating the transaction stage (with DouBao/Qwen supporting order placement and payment); ② Token services launched on Tmall and JD.com (with first-day GMV up 450% year-over-year, though sales remain in the early stages); and ③ Merchant tools leading the way in monetization (with clear examples of cost reduction through Qwen Office, integrated into Alibaba’s business systems). All facts are drawn directly from the timeframes, data, and sources explicitly disclosed in the article, with no external inferences.

Zhen’an Technology plans to acquire, through cash, no less than 51% of the equity in Shenzhen Sanwei, marking the second step in bolstering its computing power and thermal management capabilities.

Zhen’an Technology (300767.SZ) announced on October 26, 2026, that it plans to acquire, in cash, no less than 51% of the equity interest in Shenzhen Sanwei Mechanical and Electrical Equipment Co., Ltd., a transaction expected to constitute a major asset restructuring. This marks the company’s second acquisition of an affiliated thermal‑control asset within the year; earlier, in March 2026, it had acquired a 51% stake in Dongchuang Jingyi. The deal aims to strengthen its upstream precision‑manufacturing capabilities in the computing‑power thermal‑control value chain. However, the company’s core business continues to shrink, it has posted consecutive losses over the past three years, maintains high leverage, and faces an accounts‑receivable bad‑debt ratio approaching 40%, with the effectiveness of its transformation still pending verification.

GHARP: Real-Time Gaussian Head Animation from Large-Scale Reconstruction Prior

We present GHARP (Real-time Gaussian Head Animation from Large-scale Reconstruction Prior), a method that animates 3D human heads in real time from a few input images of a subject and a driving expression signal. We decouple the problem into an identity stage that builds a representation of the subject’s geometry and appearance offline, and an animation stage that predicts expression-dependent residuals on top of it at runtime. This separation offers a favorable trade-off with respect to fidelity, quality and runtime: the identity stage can be expensive while the animation stage runs a…
