Monitoring Energy Trends through Automatic Information Extraction

arXiv.org Artificial Intelligence

Energy research is of crucial public importance but the use of computer science technologies like automatic text processing and data management for the energy domain is still rare. Employing these technologies in the energy domain will be a significant contribution to the interdisciplinary topic of ``energy informatics", just like the related progress within the interdisciplinary area of ``bioinformatics". In this paper, we present the architecture of a Web-based semantic system called EneMonIE (Energy Monitoring through Information Extraction) for monitoring up-to-date energy trends through the use of automatic, continuous, and guided information extraction from diverse types of media available on the Web. The types of media handled by the system will include online news articles, social media texts, online news videos, and open-access scholarly papers and technical reports as well as various numeric energy data made publicly available by energy organizations. The system will utilize and contribute to the energy-related ontologies and its ultimate form will comprise components for (i) text categorization, (ii) named entity recognition, (iii) temporal expression extraction, (iv) event extraction, (v) social network construction, (vi) sentiment analysis, (vii) information fusion and summarization, (viii) media interlinking, and (ix) Web-based information retrieval and visualization. Wits its diverse data sources, automatic text processing capabilities, and presentation facilities open for public use; EneMonIE will be an important source of distilled and concise information for decision-makers including energy generation, transmission, and distribution system operators, energy research centres, related investors and entrepreneurs as well as for academicians, students, other individuals interested in the pace of energy events and technologies.


Challenges of Artificial Intelligence -- From Machine Learning and Computer Vision to Emotional Intelligence

arXiv.org Artificial Intelligence

Artificial intelligence (AI) has become a part of everyday conversation and our lives. It is considered as the new electricity that is revolutionizing the world. AI is heavily invested in both industry and academy. However, there is also a lot of hype in the current AI debate. AI based on so-called deep learning has achieved impressive results in many problems, but its limits are already visible. AI has been under research since the 1940s, and the industry has seen many ups and downs due to over-expectations and related disappointments that have followed. The purpose of this book is to give a realistic picture of AI, its history, its potential and limitations. We believe that AI is a helper, not a ruler of humans. We begin by describing what AI is and how it has evolved over the decades. After fundamentals, we explain the importance of massive data for the current mainstream of artificial intelligence. The most common representations for AI, methods, and machine learning are covered. In addition, the main application areas are introduced. Computer vision has been central to the development of AI. The book provides a general introduction to computer vision, and includes an exposure to the results and applications of our own research. Emotions are central to human intelligence, but little use has been made in AI. We present the basics of emotional intelligence and our own research on the topic. We discuss super-intelligence that transcends human understanding, explaining why such achievement seems impossible on the basis of present knowledge,and how AI could be improved. Finally, a summary is made of the current state of AI and what to do in the future. In the appendix, we look at the development of AI education, especially from the perspective of contents at our own university.


Hi-tech and eco-friendly 'carcopter' could replace Formula 1 as a sport, say manufacturers

Daily Mail - Science & tech

It looks like a futuristic racing craft from a video game popular more than 25 years ago. But this insect-like flying car should soon be a reality. French company Maca says it plans to test its eco-friendly £665,000 hydrogen-powered'carcopter' on racetracks this year. It will have a top speed of 155mph, meaning a pilot onboard the 23ft craft can give Formula One stars a run for their money. But unlike the gas-guzzling machines driven by Sir Lewis Hamilton and co, this vehicle does not create any CO2 emissions and is fully recyclable.

China's nuclear fusion reactor runs at 126MILLION F for 17 minutes

Daily Mail - Science & tech

China's'artificial sun' nuclear fusion reactor in Hefei has set a new world record after running at 126 million F (70 million C) for 1,056 seconds – more than 17 minutes. This record, set on December 30, marks the longest running duration for an experimental advanced superconducting tokamak (EAST) fusion energy reactor, Xinhua News Agency reports. EAST already set a previous record in May by running for 101 seconds at a higher temperature – 216 million F (120 million C). Nuclear fusion power works by colliding heavy hydrogen atoms to form helium, releasing vast amounts of energy, mimicking the process that occurs naturally in the centre of stars like our sun. How it works: This graphic shows the inside of a nuclear fusion reactor and explains the process by which power is produced.

Daily Mail - Science & tech

The Consumer Electronics Show (CES) 2022 is underway, kicking off with its'Unveiled' vent on Monday evening that provided a sneak peak into what we can expect to be showcased at the tech conference. Attendees saw several new technologies including a Star Wars-like face mask that protects against pollution and the coronavirus, a wearable that stops premature ejaculation and a brain scanning device that can detect early signs of mental conditions. Monday's event also hosted several innovations that were awarded the CES 2022 Innovation Award, which was given to Kura for its AR glasses and solar shingles that can be nailed directly to the roof. CES, which is held in Las Vegas, is expected to host more than 50,000 people and 2,200 exhibitors, but is also closing its doors a day early due to coronavirus cases spiking around the US. Among those showcasing their latest and greatest innovations was Airxom Mask - a mask with a white plastic shell that covers the mouth and nose.


Keeping one step ahead of earthquakes

AIHub

Damaging earthquakes can strike at any time. While we can't prevent them from occurring, we can make sure casualties, economic loss and disruption of essential services are kept to a minimum. Building more resilient cities is key to withstanding earthquake disasters. If we had a better idea of when earthquakes would strike, authorities could initiate local emergency, evacuation and shelter plans. But unfortunately, this is not the case.


Visual Microfossil Identification via Deep Metric Learning

arXiv.org Artificial Intelligence

We apply deep metric learning for the first time to the prob-lem of classifying planktic foraminifer shells on microscopic images. This species recognition task is an important information source and scientific pillar for reconstructing past climates. All foraminifer CNN recognition pipelines in the literature produce black-box classifiers that lack visualisation options for human experts and cannot be applied to open set problems. Here, we benchmark metric learning against these pipelines, produce the first scientific visualisation of the phenotypic planktic foraminifer morphology space, and demonstrate that metric learning can be used to cluster species unseen during training. We show that metric learning out-performs all published CNN-based state-of-the-art benchmarks in this domain. We evaluate our approach on the 34,640 expert-annotated images of the Endless Forams public library of 35 modern planktic foraminifera species. Our results on this data show leading 92% accuracy (at 0.84 F1-score) in reproducing expert labels on withheld test data, and 66.5% accuracy (at 0.70 F1-score) when clustering species never encountered in training. We conclude that metric learning is highly effective for this domain and serves as an important tool towards expert-in-the-loop automation of microfossil identification. Key code, network weights, and data splits are published with this paper for full reproducibility.

Learning Operators with Coupled Attention

arXiv.org Artificial Intelligence

Supervised operator learning is an emerging machine learning paradigm with applications to modeling the evolution of spatio-temporal dynamical systems and approximating general black-box relationships between functional data. We propose a novel operator learning method, LOCA (Learning Operators with Coupled Attention), motivated from the recent success of the attention mechanism. In our architecture, the input functions are mapped to a finite set of features which are then averaged with attention weights that depend on the output query locations. By coupling these attention weights together with an integral transform, LOCA is able to explicitly learn correlations in the target output functions, enabling us to approximate nonlinear operators even when the number of output function in the training set measurements is very small. Our formulation is accompanied by rigorous approximation theoretic guarantees on the universal expressiveness of the proposed model. Empirically, we evaluate the performance of LOCA on several operator learning scenarios involving systems governed by ordinary and partial differential equations, as well as a black-box climate prediction problem. Through these scenarios we demonstrate state of the art accuracy, robustness with respect to noisy input data, and a consistently small spread of errors over testing data sets, even for out-of-distribution prediction tasks.
