WebThinker: Empowering Large Reasoning Models with Deep Research Capability

Neural Information Processing Systems

Large reasoning models (LRMs), such as OpenAI-o1 and DeepSeek-R1, demonstrate impressive long-horizon reasoning capabilities. However, their reliance on static internal knowledge limits their performance on complex, knowledge-intensive tasks and hinders their ability to produce comprehensive research reports requiring synthesis of diverse web information. To address this, we propose WebThinker, a deep research agent that empowers LRMs to autonomously search the web, navigate among web pages, and draft reports during the reasoning process. WebThinker integrates a Deep Web Explorer module, enabling LRMs to dynamically search, navigate, and extract information from the web when encountering knowledge gaps. It also employs an Autonomous Think-Search-and-Draft strategy, allowing the model to seamlessly interleave reasoning, information gathering, and report writing in real time. To further enhance research tool utilization, we introduce an RL-based training strategy via iterative online Direct Preference Optimization (DPO). Extensive experiments on complex reasoning benchmarks (GPQA, GAIA, WebWalkerQA, HLE) and scientific report generation tasks (Glaive) demonstrate that WebThinker significantly outperforms existing methods and strong proprietary systems. Our approach enhances LRM reliability and applicability in complex scenarios, paving the way for more capable and versatile deep research systems.


TopER: Topological Embeddings in Graph Representation Learning

Neural Information Processing Systems

Graph embeddings play a critical role in graph representation learning, allowing machine learning models to explore and interpret graph-structured data. However, existing methods often rely on opaque, high-dimensional embeddings, limiting interpretability and practical visualization. In this work, we introduce Topological Evolution Rate (TopER), a novel, lowdimensional embedding approach grounded in topological data analysis.


Trump Mocked Mark Zuckerberg and Jeff Bezos by Showing Off Fawning Texts

WIRED

"You would not believe the texts I got from these tech guys," NYT reporters Maggie Haberman and Jonathan Swan quote Donald Trump as telling associates in an upcoming book. Meta CEO Mark Zuckerberg and Amazon founder Jeff Bezos sought to ingratiate themselves with President Donald Trump after he won the 2024 election, and in return he mocked their efforts behind their backs, according to a new book by The New York Times reporters Maggie Haberman and Jonathan Swan. Zuckerberg once texted Trump a photo of a letter written by one of his grade-school-age children, who wrote that they "looked forward to the golden age of America," a slogan Trump had repeated at rallies during the presidential campaign. And over dinner at Trump's Mar-a-Lago club, Bezos denigrated The Washington Post to Trump and essentially described the newspaper as one of his worst financial investments, months before he unsuccessfully sought a business favor from the president. These episodes are detailed in the book, a copy of which WIRED obtained ahead of its release on June 23.

GAMMA: Gated Multi-hop Message Passing for Homophily-Agnostic Node Representation in GNNs

Neural Information Processing Systems

The success of Graph Neural Networks (GNNs) leverages the homophily principle, where connected nodes share similar features and labels. However, this assumption breaks down in heterophilic graphs, where same-class nodes are often distributed across distant neighborhoods rather than immediate connections. Recent attempts expand the receptive field through multi-hop aggregation schemes that explicitly preserve intermediate representations from each hop distance. While effective at capturing heterophilic patterns, these methods require separate weight matrices per hop and feature concatenation, causing parameters to scale linearly with hop count. This leads to high computational complexity and GPU memory consumption. We propose Gated Multi-hop Message Passing (GAMMA), where nodes assess how relevant the aggregated information is from their k-hop neighbors. This assessment occurs through multiple refinement steps where the node compares each hop's embedding with its current representation, allowing it to focus on the most informative hops. During the forward pass, GAMMA finds the optimal mix of multi-hop information local to each node using a single feature vector without needing separate representations for each hop, thereby maintaining dimensionality comparable to single hop GNNs. In addition, we propose a weight sharing scheme that leverages a unified transformation for aggregated features from multiple hops so the global heterophilic patterns specific to each hop are learned during training.


Florida lawsuit alleges wrongful arrest after AI facial recognition error

The Guardian

A Florida man is suing several law enforcement agencies for his arrest and prosecution for allegedly luring a child after he was wrongly identified using faulty AI facial recognition software. According to the Jacksonville Beach police department, an algorithm returned a 93% probability that Robert Dillon was the man caught on security cameras at a McDonald's in the town attempting to persuade an unaccompanied girl, aged younger than 12, to leave with him. Dillon, however, lives in Fort Myers, more than 300 miles and a five-hour drive away, and told detectives he had never been to Jacksonville Beach in his life. The case was dismissed and charges dropped last year over the August 2024 incident. Now the 52-year-old has filed a lawsuit against the police department, the Jacksonville sheriff's office, and Bob Gualtieri, the sheriff of Pinellas county, whose agency maintains and operates the Faces (Face Analysis Comparison and Examination) system and leases it to other law enforcement.


Wrongful Arrest Exposes Failures in One of the Oldest Police Face-Recognition Tools in the US

WIRED

The ACLU is suing two Florida police departments over the arrest of a Fort Myers man in a child-abduction case, saying officers treated a flawed face recognition match as a near-certain ID. A Florida man was wrongfully arrested for attempting to illegally lure a child after police relied on a face recognition match that was inaccurate, according to a lawsuit filed on Wednesday, even though he lived more than 300 miles from the scene and says he had never set foot in the city where the crime took place. Robert Dillon, a 52-year-old commercial crabber from Fort Myers, was arrested after FACES--a face recognition system operated by Florida's Pinellas County Sheriff's Office--matched his face against a photo of a man on a computer screen taken with a cellphone. The system returned a "93 percent match on facial features," according to police investigatory notes. The scores it emits represent how much two images look alike to the algorithm.


Alex Vindman Survived Trump's Retaliation Machine. Now He's Running for Senate

WIRED

Alex Vindman Survived Trump's Retaliation Machine. In 2019, Alex Vindman testified during President Trump's first impeachment trial--a decision that ended his military career. Now he wants to challenge the president from the halls of Congress. Alex Vindman knows a thing or two about pissing off President Donald Trump . In 2019, Vindman rose to national prominence when he served as a witness during Trump's first impeachment trial. If you've lost track of that particular scandal, it's the one involving Trump, Ukrainian president Volodymyr Zelensky, the Biden family and Vindman listening in on a troubling phone call in his capacity as the director for European affairs on the National Security Council. Vindman's congressional testimony describing that pivotal call was widely lauded, even as it ended his storied military career: After being ousted from the NSC, Vindman retired from the Army in 2020. Six years later, he's got his eye on another governmental gig. In January, Vindman announced plans to challenge Republican incumbent Ashley Moody for the Florida seat in the US Senate previously held by Marco Rubio. Vindman, who tells me he moved to Florida in 2023 because his wife wanted to politics, is the latest candidate I'm chatting with ahead of the November midterms. He's particularly interesting to me, and WIRED, for a few reasons: Vindman has lived through--and emerged from--the Trump retaliation machine, and I wanted to hear more about that journey; he's been vocal about his opposition to both the war in Iran and ICE, two topics we cover frequently; and I wanted his view, as a longtime service member, on AI through the lens of national security. Then there's the fact that Vindman, running in what's ostensibly a Republican stronghold, has a decent shot at winning the damn thing: Though Senator Moody still leads in most polls, Vindman is often within spitting distance--no small feat for a first-time candidate whose campaign started around five months ago. KATIE DRUMMOND: Welcome to the Big Interview, Alex. Good to be here with you, Katie. So glad to have you here. You are maybe best known on a national level as a whistleblower, but you were also an Army veteran of more than 20 years. You were honored with a Purple Heart after being wounded in Iraq, and you were on the National Security Council.

Support-aware offline policy selection for advertising marketplaces

arXiv.org Machine Learning

Logged advertising auctions make offline reserve-price evaluation attractive but risky. Replay tables can identify policies with large apparent yield gains, yet they can also hide weak threshold support, multiple-comparison effects, subgroup harm, and bidder-response uncertainty. Existing replay and off-policy evaluation methods estimate or rank policy values, but they do not directly answer the operational question of whether the available evidence is strong enough to justify validation. This paper develops a support-aware offline decision framework for reserve-policy selection. Rather than outputting a single point-estimate winner, the framework converts logged evidence into a conservative decision object consisting of certified policies, statistically dominated alternatives, and unresolved candidates requiring further validation. The main theoretical result gives a unified finite-catalog guarantee showing that, under simultaneous uncertainty control and conservative support gates, the framework preserves the best gate-passing policy while eliminating only policies with certified regret. Supporting results characterize support-localized replay generalization, establish information-theoretic threshold-resolution limits, and quantify when heterogeneous bidder response can overturn localized replay rankings. Experiments on iPinYou real-time-bidding logs show that the leading reserve rule achieves a 47.66% replay lift in season two, a 40.71% simultaneous lower-bound lift, and a 43.87% frozen out-of-time replay lift in season three. The framework reduces a 19-policy catalog to a two-policy validation shortlist while certifying non-harm across 44 advertiser, exchange, and region segments. The results support the central claim that offline reserve-policy evaluation should produce certified validation decisions rather than point-estimate rankings alone.
