Alibaba’s Long-Awaited China Stock Link May Provide Timely Boost

Chinese investors finally being able to buy shares of Alibaba Group Holding Ltd. may provide a much-needed boost for the e-commerce firm’s stock, with an inflow of up to about $20 billion into next year.The company first hatched the plan for an upgrade to a primary listing in Hong Kong two years ago amid heightened tensions with the US. It may at last be realized by the end of the month, paving the way for it to join a program that connects the Shanghai and Shenzhen bourses to the Hong Kong exchange. Source link lol

Joint Graph Rewiring and Feature Denoising via Spectral Resonance

Joint Graph Rewiring and Feature Denoising via Spectral Resonance

[Submitted on 13 Aug 2024] View a PDF of the paper titled Joint Graph Rewiring and Feature Denoising via Spectral Resonance, by Jonas Linkerh"agner and 2 other authors View PDF HTML (experimental) Abstract:Graph neural networks (GNNs) take as input the graph structure and the feature vectors associated with the nodes. Both contain noisy information about the labels. Here we propose joint denoising and rewiring (JDR)--an algorithm to jointly denoise the graph structure and features, which can improve the performance of any downstream algorithm. We do this by defining and maximizing the alignment between the leading eigenspaces of graph and feature…

Robust Semi-supervised Multimodal Medical Image Segmentation via Cross Modality Collaboration

Robust Semi-supervised Multimodal Medical Image Segmentation via Cross Modality Collaboration

arXiv:2408.07341v1 Announce Type: new Abstract: Multimodal learning leverages complementary information derived from different modalities, thereby enhancing performance in medical image segmentation. However, prevailing multimodal learning methods heavily rely on extensive well-annotated data from various modalities to achieve accurate segmentation performance. This dependence often poses a challenge in clinical settings due to limited availability of such data. Moreover, the inherent anatomical misalignment between different imaging modalities further complicates the endeavor to enhance segmentation performance. To address this problem, we propose a novel semi-supervised multimodal segmentation framework that is robust to scarce labeled data and misaligned modalities. Our framework employs a novel…

From Brazilian Portuguese to European Portuguese

From Brazilian Portuguese to European Portuguese

arXiv:2408.07457v1 Announce Type: new Abstract: Brazilian Portuguese and European Portuguese are two varieties of the same language and, despite their close similarities, they exhibit several differences. However, there is a significant disproportion in the availability of resources between the two variants, with Brazilian Portuguese having more abundant resources. This inequity can impact the quality of translation services accessible to European Portuguese speakers. To address this issue, we propose the development of a Brazilian Portuguese to European Portuguese translation system, leveraging recent advancements in neural architectures and models. To evaluate the performance of such systems, we manually curated a gold test…

Congress asks Mark Zuckerberg to explain why drug dealers are advertising on Facebook and Instagram

Congress asks Mark Zuckerberg to explain why drug dealers are advertising on Facebook and Instagram

Nineteen members of Congress Mark Zuckerberg to explain why Meta has allowed ads for cocaine, ecstasy and other drugs to be shown on Facebook and Instagram. The letter comes after the Tech Transparency Project (TTP) uncovered hundreds of such ads on the company’s platform.The letter points to the TTP’s report , which used Meta’s ad library to find 450 Instagram and Facebook ads “selling an array of pharmaceutical and other drugs.” Many of those ads included “photos of prescription drug bottles, piles of pills and powders, or bricks of cocaine,” and directed viewers to outside apps like Telegram. Since then,…

An exploding star is due to show up in our skies for the first time in almost 80 years — here’s how to spot this ‘once-in-a-lifetime event’

An exploding star is due to show up in our skies for the first time in almost 80 years — here’s how to spot this ‘once-in-a-lifetime event’

Astronomers anticipate that a nearby exploding star could appear in the night skies across the Northern Hemisphere.The star is part of an eruptive two-star system called T Coronae Borealis, located 3,000 light years away.Every 80 years or so, one of the stars emits a powerful cosmic burst of energy called a nova. One expert told The New York Times these novae are "basically hydrogen bombs."No need to worry — T Coronae Borealis is much too far for that energy to harm us on Earth. But it will appear as a new star in our night sky for a few days.Don't…

The right-wing side of Silicon Valley is railing against Harris’ economic speech before it even happens

The right-wing side of Silicon Valley is railing against Harris’ economic speech before it even happens

After the Harris campaign shared details of what to expect from the candidate's economic policy speech on Friday, some big-wigs in Silicon Valley lost no time in bashing the yet unspoken proposals. In particular, they slammed her plan to impose the first federal ban on corporate price-gouging and high grocery costs.According to the campaign, Harris intends to enact the ban within the first 100 days of her presidency, as well as empower the FTC and state attorneys general to investigate and punish corporations that break the rules. She will also instruct her administration to look into proposed mergers between large…

A POD-TANN approach for the multiscale modeling of materials and macroelement derivation in geomechanics

A POD-TANN approach for the multiscale modeling of materials and macroelement derivation in geomechanics

arXiv:2408.07165v1 Announce Type: new Abstract: This paper introduces a novel approach that combines Proper Orthogonal Decomposition (POD) with Thermodynamics-based Artificial Neural Networks (TANN) to capture the macroscopic behavior of complex inelastic systems and derive macroelements in geomechanics. The methodology leverages POD to extract macroscopic Internal State Variables (ISVs) from microscopic state information, thereby enriching the macroscopic state description used to train an energy potential network within the TANN framework. The thermodynamic consistency provided by TANN, combined with the hierarchical nature of POD, allows for accurate modeling of complex, non-linear material behavior and reliable macroscopic geomechanical systems responses. The effectiveness of…

KIND: Knowledge Integration and Diversion in Diffusion Models

KIND: Knowledge Integration and Diversion in Diffusion Models

arXiv:2408.07337v1 Announce Type: new Abstract: Pre-trained models have become the preferred backbone due to the expansion of model parameters, with techniques like Parameter-Efficient Fine-Tuning (PEFTs) typically fixing the parameters of these models. However, pre-trained models may not always be optimal, especially when there are discrepancies between training tasks and target tasks, potentially resulting in negative transfer. To address this, we introduce textbf{KIND}, which performs textbf{K}nowledge textbf{IN}tegration and textbf{D}iversion in diffusion models. KIND first integrates knowledge by decomposing parameter matrices of models using $U$, $Sigma$, and $V$ matrices, formally inspired by singular value decomposition (SVD). Then it explicitly partitions the components…
