Using Time-Aware Graph Neural Networks to Predict Temporal Centralities in Dynamic Graphs

Neural Information Processing Systems

Node centralities play a pivotal role in network science, social network analysis, and recommender systems.In temporal data, static path-based centralities like closeness or betweenness can give misleading results about the true importance of nodes in a temporal graph. To address this issue, temporal generalizations of betweenness and closeness have been defined that are based on the shortest time-respecting paths between pairs of nodes. However, a major issue of those generalizations is that the calculation of such paths is computationally expensive.Addressing this issue, we study the application of De Bruijn Graph Neural Networks (DBGNN), a time-aware graph neural network architecture, to predict temporal path-based centralities in time series data. We experimentally evaluate our approach in 13 temporal graphs from biological and social systems and show that it considerably improves the prediction of betweenness and closeness centrality compared to (i) a static Graph Convolutional Neural Network, (ii) an efficient sampling-based approximation technique for temporal betweenness, and (iii) two state-of-the-art time-aware graph learning techniques for dynamic graphs.


Re-assembling the past: The RePAIR dataset and benchmark for real world 2D and 3D puzzle solving

Neural Information Processing Systems

This paper proposes the RePAIR dataset that represents a challenging benchmark to test modern computational and data driven methods for puzzle-solving and reassembly tasks. Our dataset has unique properties that are uncommon to current benchmarks for 2D and 3D puzzle solving. The fragments and fractures are realistic, caused by a collapse of a fresco during a World War II bombing at the Pompeii archaeological park. The fragments are also eroded and have missing pieces with irregular shapes and different dimensions, challenging further the reassembly algorithms. The dataset is multi-modal providing high resolution images with characteristic pictorial elements, detailed 3D scans of the fragments and meta-data annotated by the archaeologists. Ground truth has been generated through several years of unceasing fieldwork, including the excavation and cleaning of each fragment, followed by manual puzzle solving by archaeologists of a subset of approx.

Inventor Beulah Louise Henry's unstoppable rise to becoming 'Lady Edison'

Popular Science

With 49 patents and over 100 inventions, Henry built an empire catering to women and children. Beulah Louise Henry invented everything from ice cream makers to radio dolls--despite a world that didn't take her seriously. Breakthroughs, discoveries, and DIY tips sent six days a week. Beulah Louise Henry was just nine years old when she came up with her first invention in 1896, a device that allowed a man to tip his hat without ever putting down his newspaper. By her death in 1973, at the age of 85, she'd come up with so many more--a doll with eyes that changed color with the press of a button, a sewing machine without a bobbin (a threaded spool that slowed down work because it had to be frequently refilled), a clock designed to help kids learn to tell time, and others--that the press even dubbed Henry "Lady Edison."


Afroman wins legal battle over songs mocking US police

BBC News

US rapper Afroman has defeated seven sheriff's deputies in a court case after they sued him for releasing songs and videos that mocked them and a raid they carried out on his home. The officers broke down the musician's door in 2022 as part of a drug and kidnapping investigation, but the raid didn't lead to any charges. Afroman, best known for his 2000 hit Because I Got High, responded by using home security footage in viral videos that ridiculed the deputies. His video for the song Lemon Pound Cake was inspired by a deputy apparently eyeing a cake in his kitchen, while another video attributed personal and sexual transgressions to the officers. They sued him for defamation, but a jury has sided with the colourful rapper after a three-day trial. Afroman yelled outside the Ohio court, surrounded by supporters, in a clip posted on social media after the verdict.


The Download: Quantum computing for health, and why the world doesn't recycle more nuclear waste

MIT Technology Review

The Download: Quantum computing for health, and why the world doesn't recycle more nuclear waste Plus: The FBI has admitted it's buying Americans' location data. In a laboratory on the outskirts of Oxford, a quantum computer built from atoms and light awaits its moment. The device is small but powerful--and also very valuable. Infleqtion, the company that owns it, is hoping its abilities will win $5 million at a competition next week. The prize will go to the quantum computer that can solve real health care problems that conventional "classical" computers are unable to solve. But there can be only one big winner--if there is a winner at all.

The Men Obsessed With 'High T'

WIRED

Fueled by the manosphere, men are boosting their testosterone levels through natural and synthetic means, with some competitively swapping test results on a regular basis. Mark Holman was skinny and depressed when he was working a 9-to-5 job as an air quality engineering consultant in 2018. "I felt weak, like a boy," says the 33-year-old New Orleans native. Determined to turn things around, he spent the next few years becoming a health coach and getting chiseled abs. But in 2021, after becoming perplexed as to why he was disinterested in sex with his partner at the time, he decided to test his testosterone levels.


Can quantum computers now solve health care problems? We'll soon find out.

MIT Technology Review

I'm standing in front of a quantum computer built out of atoms and light at the UK's National Quantum Computing Centre on the outskirts of Oxford. On a laboratory table, a complex matrix of mirrors and lenses surrounds a Rubik's Cube-size cell where 100 cesium atoms are suspended in grid formation by a carefully manipulated laser beam. The cesium atom setup is so compact that I could pick it up, carry it out of the lab, and put it on the backseat of my car to take home. I'd be unlikely to get very far, though.
