Christmas Island
Google planning powerful AI data center on tiny Australian outpost
Red crabs walk across a road in Christmas Island, Australia, in October. SYDNEY - Google plans to build a large artificial intelligence data center on Australia's remote Indian Ocean outpost of Christmas Island after signing a cloud deal with the Department of Defence earlier this year, according to documents and interviews with officials. Plans for the data center on the tiny island located 350 kilometers south of Indonesia have not previously been reported, and many details including its projected size, cost and potential uses, remain secret. However, military experts say such a facility would be a valuable asset on the island, which is increasingly seen by defense officials as a critical front line in monitoring Chinese submarine and other naval activity in the Indian Ocean. In a time of both misinformation and too much information, quality journalism is more crucial than ever.
The Download: carbon removal's future, and measuring pain using an app
Plus: Meta's lawyers advised staff to remove parts of their research After years of growth that spawned hundreds of startups, the nascent carbon removal sector appears to be facing a reckoning. Running Tide, a promising aquaculture company, shut down its operations last summer, and a handful of other companies have shuttered, downsized, or pivoted in recent months as well. And the collective industry hasn't made a whole lot more progress toward Running Tide's ambitious plans to sequester a billion tons of carbon dioxide by this year. The hype phase is over and the sector is sliding into the turbulent business trough that follows, experts warn. And the open question is: If the carbon removal sector is heading into a painful if inevitable clearing-out cycle, where will it go from there? This story is part of MIT Technology Review's What's Next series, which looks across industries, trends, and technologies to give you a first look at the future.
Ecological Neural Architecture Search
Winter, Benjamin David, Teahan, William J.
When employing an evolutionary algorithm to optimize a neural networks architecture, developers face the added challenge of tuning the evolutionary algorithm's own hyperparameters - population size, mutation rate, cloning rate, and number of generations. This paper introduces Neuvo Ecological Neural Architecture Search (ENAS), a novel method that incorporates these evolutionary parameters directly into the candidate solutions' phenotypes, allowing them to evolve dynamically alongside architecture specifications. Experimental results across four binary classification datasets demonstrate that ENAS not only eliminates manual tuning of evolutionary parameters but also outperforms competitor NAS methodologies in convergence speed (reducing computational time by 18.3%) and accuracy (improving classification performance in 3 out of 4 datasets). By enabling "greedy individuals" to optimize resource allocation based on fitness, ENAS provides an efficient, self-regulating approach to neural architecture search.
Sunken WWII US destroyer, known as 'Dancing Mouse,' discovered 80 years after battle with Japanese
The wreckage of the USS Edsall, an American warship that was sunk during a battle with Japanese forces in World War II, has been discovered more than 80 years after it was lost at the bottom of the sea, U.S. and Australian officials announced Monday. The final resting place of the USS Edsall, a Clemson-class destroyer, was discovered late last year at the bottom of the Indian Ocean, according to the U.S. Navy and Royal Australian Navy. "Working in collaboration with the U.S. Navy, the Royal Australian Navy used advanced robotic and autonomous systems, normally used for hydrographic survey capabilities, to locate USS Edsall on the sea-bed," Chief of Royal Australian Navy, Vice Admiral Mark Hammond, said in a statement. The warship was sunk on March 1, 1942, three months after the attack on Pearl Harbor, during an encounter with Japanese battleships and dive bombers. The USS Edsall was a Clemson-class destroyer, measuring 314 feet in length and capable of 35 knots.
MIRAI: Evaluating LLM Agents for Event Forecasting
Ye, Chenchen, Hu, Ziniu, Deng, Yihe, Huang, Zijie, Ma, Mingyu Derek, Zhu, Yanqiao, Wang, Wei
Recent advancements in Large Language Models (LLMs) have empowered LLM agents to autonomously collect world information, over which to conduct reasoning to solve complex problems. Given this capability, increasing interests have been put into employing LLM agents for predicting international events, which can influence decision-making and shape policy development on an international scale. Despite such a growing interest, there is a lack of a rigorous benchmark of LLM agents' forecasting capability and reliability. To address this gap, we introduce MIRAI, a novel benchmark designed to systematically evaluate LLM agents as temporal forecasters in the context of international events. Our benchmark features an agentic environment with tools for accessing an extensive database of historical, structured events and textual news articles. We refine the GDELT event database with careful cleaning and parsing to curate a series of relational prediction tasks with varying forecasting horizons, assessing LLM agents' abilities from short-term to long-term forecasting. We further implement APIs to enable LLM agents to utilize different tools via a code-based interface. In summary, MIRAI comprehensively evaluates the agents' capabilities in three dimensions: 1) autonomously source and integrate critical information from large global databases; 2) write codes using domain-specific APIs and libraries for tool-use; and 3) jointly reason over historical knowledge from diverse formats and time to accurately predict future events. Through comprehensive benchmarking, we aim to establish a reliable framework for assessing the capabilities of LLM agents in forecasting international events, thereby contributing to the development of more accurate and trustworthy models for international relation analysis.

Digital Divides in Scene Recognition: Uncovering Socioeconomic Biases in Deep Learning Systems
Greene, Michelle R., Josyula, Mariam, Si, Wentao, Hart, Jennifer A.
Computer-based scene understanding has influenced fields ranging from urban planning to autonomous vehicle performance, yet little is known about how well these technologies work across social differences. We investigate the biases of deep convolutional neural networks (dCNNs) in scene classification, using nearly one million images from global and US sources, including user-submitted home photographs and Airbnb listings. We applied statistical models to quantify the impact of socioeconomic indicators such as family income, Human Development Index (HDI), and demographic factors from public data sources (CIA and US Census) on dCNN performance. Our analyses revealed significant socioeconomic bias, where pretrained dCNNs demonstrated lower classification accuracy, lower classification confidence, and a higher tendency to assign labels that could be offensive when applied to homes (e.g., "ruin", "slum"), especially in images from homes with lower socioeconomic status (SES). This trend is consistent across two datasets of international images and within the diverse economic and racial landscapes of the United States. This research contributes to understanding biases in computer vision, emphasizing the need for more inclusive and representative training datasets. By mitigating the bias in the computer vision pipelines, we can ensure fairer and more equitable outcomes for applied computer vision, including home valuation and smart home security systems. There is urgency in addressing these biases, which can significantly impact critical decisions in urban development and resource allocation. Our findings also motivate the development of AI systems that better understand and serve diverse communities, moving towards technology that equitably benefits all sectors of society.
Detecting agreement in multi-party dialogue: evaluating speaker diarisation versus a procedural baseline to enhance user engagement
Addlesee, Angus, Denley, Daniel, Edmondson, Andy, Gunson, Nancie, Garcia, Daniel Hernández, Kha, Alexandre, Lemon, Oliver, Ndubuisi, James, O'Reilly, Neil, Perochaud, Lia, Valeri, Raphaël, Worika, Miebaka
Conversational agents participating in multi-party interactions face significant challenges in dialogue state tracking, since the identity of the speaker adds significant contextual meaning. It is common to utilise diarisation models to identify the speaker. However, it is not clear if these are accurate enough to correctly identify specific conversational events such as agreement or disagreement during a real-time interaction. This study uses a cooperative quiz, where the conversational agent acts as quiz-show host, to determine whether diarisation or a frequency-and-proximity-based method is more accurate at determining agreement, and whether this translates to feelings of engagement from the players. Experimental results show that our procedural system was more engaging to players, and was more accurate at detecting agreement, reaching an average accuracy of 0.44 compared to 0.28 for the diarised system.

Liu, Fuxiao, Yacoob, Yaser, Shrivastava, Abhinav
We introduce a new benchmark, COVID-VTS, for fact-checking multi-modal information involving short-duration videos with COVID19- focused information from both the real world and machine generation. We propose, TwtrDetective, an effective model incorporating cross-media consistency checking to detect token-level malicious tampering in different modalities, and generate explanations. Due to the scarcity of training data, we also develop an efficient and scalable approach to automatically generate misleading video posts by event manipulation or adversarial matching. We investigate several state-of-the-art models and demonstrate the superiority of TwtrDetective.
