Guaranteed Fast Implementation of the Split Covariance Intersection Filter: Nested Newton Method Thanks to the Fourth-Order Convexity of w-Optimization
arXiv:2606.09505v1 Announce Type: new Abstract: The split covariance intersection filter (Split CIF) is a useful tool for general data fusion and has the potential to be applied in a variety of engineering tasks. The w-optimization problem involved in the Split CIF concerns the performance and implementation efficiency of the Split CIF. It is known that the w-optimization problem enjoys the desirable property of convexity (or more clearly, the second-order convexity in this paper's context).
Several MPs head for Delhi, TMC’s Lok Sabha unit stares at split
After a split in its state legislative wing, Trinamool’s parliamentary party is also headed for a split, with several MPs already in New Delhi or expected to reach there by next week. Anticipating the development during a party National Working Committee meeting at her residence on Friday, Mamata Banerjee clipped national general secretary Abhishek Banerjee’s wings by appointing senior MPs Derek O’Brien and Dola Sen as joint national secretaries. Abhishek’s growing clout and style of...

From split to stitch-up? Shiva Sena factions hint at reunion amid BJP's dominance
Four years after a dramatic split turned the Shiv Sena into two rival camps locked in a bitter political battle, leaders from both sides now appear to be finding common ground on one issue: the BJP. Interestingly, the very factor that contributed to the Sena's split, its relationship with the BJP, is now emerging as a reason for calls to reunite. Senior leaders from the factions led by Uddhav Thackeray and deputy chief minister Eknath Shinde have suggested that the bigger challenge facing...
Information-Theoretic Bounds for Sparse Covariance Estimation in the Vertical-Split Distributed Model
Announce Type: new Abstract: We study the minimax estimation error for distributed covariance matrix estimation in the vertical-split (feature-split) setting, where two agents each observe different coordinates of $m$ i.i.d. and communicate a limited number of bits to a central server. [2025] established nearly tight bounds for dense (unstructured) cross-covariance matrices, we investigate whether imposing elementwise $s$-sparsity on the cross-covariance $C_{21}$ can reduce the required...
Evaluating Multimodal Steganalysis for Split-Payload Audiovisual Steganography
arXiv:2606.08726v1 Announce Type: new Abstract: The aim of steganography is to hide secret information inside ordinary media so that the existence of communication is hidden rather than encrypted. In audiovisual context, the availability of audio and video streams creates an opportunity to split a payload across these two modes thus, reducing the embedding burden on any single carrier. This paper evaluates whether such split-payload audiovisual steganography can help evade unimodal and...
Trump seeks to split Lebanon talks from war on Iran negotiations
Trump seeks to split Lebanon talks from war on Iran negotiations Trump seeks to split Lebanon talks from war on Iran negotiations US President Donald Trump says he wants to keep talks on the conflict in Lebanon separate from negotiations over the war between the US and Iran. Trump has been pressing Israel to halt its attacks on Lebanon, but the bombardment in the south has continued, undermining a potential deal with Iran which insists the two tracks are inseparable.

Federated Learning with Enhanced Privacy via Model Splitting and Random Client Participation
arXiv:2509.25906v2 Announce Type: replace Abstract: Federated Learning (FL) often adopts differential privacy (DP) to protect client data, but the added noise required for privacy guarantees can substantially degrade model accuracy. To resolve this challenge, we propose model-splitting privacy-amplified federated learning (MS-PAFL), a novel framework that combines structural model splitting with statistical privacy amplification. In this framework, each client's model is partitioned into a...
