Incomplete multi-view data, where certain views are entirely missing for some samples, poses significant challenges for traditional multi-view clustering methods. Existing deep incomplete multi-view clustering approaches often rely on static fusion strategies or two-stage pipelines, leading to suboptimal fusion results and error propagation issues. To address these limitations, this paper proposes a novel incomplete multi-view clustering framework based on Hierarchical Semantic Alignment and Cooperative Completion (HSACC). HSACC achieves robust cross-view fusion through a dual-level semantic space design. In the low-level semantic space, consistency alignment is ensured by maximizing mutual information across views. In the high-level semantic space, adaptive view weights are dynamically assigned based on the distributional affinity between individual views and an initial fused representation, followed by weighted fusion to generate a unified global representation. Additionally, HSACC implicitly recovers missing views by projecting aligned latent representations into high-dimensional semantic spaces and jointly optimizes reconstruction and clustering objectives, enabling cooperative learning of completion and clustering. Experimental results demonstrate that HSACC significantly outperforms state-of-the-art methods on five benchmark datasets. Ablation studies validate the effectiveness of the hierarchical alignment and dynamic weighting mechanisms, while parameter analysis confirms the model's robustness to hyperparameter variations.

Who will control Africa's AI infrastructure, and at what cost? In April, African Union ministers gathered in Tangier, Morocco, to discuss artificial intelligence at a moment when governments across the continent are racing to develop AI strategies, attract investment and expand digital infrastructure. Beneath the enthusiasm, however, sits a more fundamental question. As foreign technology companies invest in data centres, cloud services and AI systems across Africa, how much control will African countries ultimately have over the infrastructure on which those technologies depend? The debate reflects a broader shift in how policymakers are thinking about AI.

Anthropic's critics argue it's rapidly accumulating power. The company says that's what responsible AI development looks like. Anthropic has spent the last five years warning the world about how advanced artificial intelligence could enable mass destruction, destabilize society, and cause a litany of other grave harms. But simultaneously, it has become one of the most powerful forces pushing AI capabilities forward. The company is now among the top developers and distributors of cutting-edge AI models and courts customers like the US military.

Apple has dramatically jacked up the price of MacBooks, making the current Prime Day pricing that much more enticing. The company called price increases on its products "inevitable" just a couple of weeks ago. On Thursday afternoon, they became official on Apple's website. Its flashy new MacBook Neo is up $100, now at $699. Meanwhile, the MacBook Air gets a $200 price hike, now starting at $1,299.

Amazon-owned MGM Studios' decision to drop the OpenAI movie is just part of AI and film industries becoming increasingly intertwined. On, we take a look at where this is all headed. This week on Uncanny Valley, our hosts discuss Amazon's controversial decision to drop Luca Guadagnino's film about OpenAI's Sam Altman--which reportedly did not paint him in a favorable light. Alongside Google DeepMind's $75 million brand new partnership with indie film studio A24, how much of a dent is AI actually having in the films we see? They also dive into the recent upheaval of workers--from electricians to software engineers--against data centers. Plus: Meta's program to track employees' data gets paused after a massive leak, and Anthropic is now getting along with the government thanks to CEO Dario Amodei no longer being in the room.

OpenAI will initially only release ChatGPT 5.6 to government-approved customers OpenAI will initially only release ChatGPT 5.6 to government-approved customers You may not be able to use the new ChatGPT 5.6 as soon as it's finished. According to a report in, OpenAI plans to stagger the release of its new AI model, and the first users will only be parties that are approved by the federal government. The publication's sources said that, according to a staff memo from CEO Sam Altman, federal leaders will be approving access customer by customer during this preview period, hopefully followed a couple of weeks later by a more general release of the 5.6 model. We've made clear to the US government that this is not our preferred long term model, and will work with them and others in industry to achieve a more sustainable approach for future releases, Altman reportedly told employees in the memo. Several agencies appear to be involved in directing the change in course from OpenAI.

NSFW uses account for well over half of traffic, a new report says. We've seen that play out in some disastrous ways over the last year, but we're now gaining some insight into why the company has leaned so hard into that strategy despite some veritable PR disasters. It turns out that NSFW activities account for well over half of Grok's traffic, according to a new report in that cites two former employees of the SpaceX-owned company. That includes using Grok to generate actual porn, as well as adult role-play chats and huge volumes of requests for erotica. Grok's users have even apparently discovered that it's cheaper to channel such requests through the company's models intended for writing code because those are cheaper to use.

Graph Neural Networks (GNNs) have achieved great success but are often considered to be challenged by varying levels of homophily in graphs. Recent empirical studies have surprisingly shown that homophilic GNNs can perform well across datasets of different homophily levels with proper hyperparameter tuning, but the underlying theory and effective architectures remain unclear.

I just took a quick break from Prime Day to do a 15-minute workout on the Hydrow Arc rowing machine . Hydrow is the Peloton of rowing machines. The Arc is the top-of-the-line offering from Hydrow, which makes touchscreen-enabled machines that provide real-time stats and gentle coaching via video, and it is sadly not for sale on Amazon or during Amazon's annual event. However, two other machines from Hydrow are included, among them the successor to the original, which we gave an 8/10 review during the late pandemic home-workout boom . The Wave is 11 percent off, while the Origin is discounted by almost 25 percent.
