How to prepare your business to benefit from AI IOL Business Report
JOHANNESBURG – If data is the new oil, artificial intelligence (AI) can arguably be its best drill, able to uncover insights and mine real business value from the huge and complex data sets that typify modern organisations. Enterprises are not blind to the massive opportunities that can be extracted: according to the latest Gartner data, enterprise adoption of AI has grown 270% over the past four years. In the last year alone, AI adoption has essentially tripled within enterprises of all sizes. That's not surprising considering 85% of global CEOs believe AI will fundamentally change the way they conduct business within the next five years. Until recently, the majority of business decision-making was predominantly driven by human centric capabilities.
Flood Prediction Using Machine Learning Models: Literature Review
Mosavi, Amir, Ozturk, Pinar, Chau, Kwok-wing
Floods are among the most destructive natural disasters, which are highly complex to model. The research on the advancement of flood prediction models contributed to risk reduction, policy suggestion, minimization of the loss of human life, and reduction the property damage associated with floods. To mimic the complex mathematical expressions of physical processes of floods, during the past two decades, machine learning (ML) methods contributed highly in the advancement of prediction systems providing better performance and cost-effective solutions. Due to the vast benefits and potential of ML, its popularity dramatically increased among hydrologists. Researchers through introducing novel ML methods and hybridizing of the existing ones aim at discovering more accurate and efficient prediction models. The main contribution of this paper is to demonstrate the state of the art of ML models in flood prediction and to give insight into the most suitable models. In this paper, the literature where ML models were benchmarked through a qualitative analysis of robustness, accuracy, effectiveness, and speed are particularly investigated to provide an extensive overview on the various ML algorithms used in the field. The performance comparison of ML models presents an in-depth understanding of the different techniques within the framework of a comprehensive evaluation and discussion. As a result, this paper introduces the most promising prediction methods for both long-term and short-term floods. Furthermore, the major trends in improving the quality of the flood prediction models are investigated. Among them, hybridization, data decomposition, algorithm ensemble, and model optimization are reported as the most effective strategies for the improvement of ML methods.
Agglomerative Fast Super-Paramagnetic Clustering
Concretely, that the proposed algorithm does in fact recover the correct super-paramagnetic cluster configurations that are near the entropy maxima. Previous cases studies include data clustering of stocks [15] and gene data in [4], temporal states of financial markets [8], and state-detection for adaptive machine learning in trading [5]. There is an endless variety of potential use-cases for this type of fast big-data clustering technology. Building on prior work we propose and demonstrate an alternative to fast Super-Paramagnetic Clustering (f-SPC) [15] using a modern and streamlined implementation of the "Merging Algorithm" first suggested by Gi-ada [4], one that can recover the same cluster configurations for a variety of test-cases, but with significantly reduced compute times. We again use the Noh Ansatz [11] and the Maximum Likelihood Estimation approach introduced by Giada and Marsili [4]. We call the new algorithm Agglomerative Super-Paramagnetic Clustering (ASPC) and it has the benefit of being less computationally expensive than the PGAs implemented in [5, 6, 15].
Animal Wildlife Population Estimation Using Social Media Images Collections
Foglio, Matteo, Semeria, Lorenzo, Muscioni, Guido, Pressiani, Riccardo, Berger-Wolf, Tanya
We are losing biodiversity at an unprecedented scale and in many cases, we do not even know the basic data for the species. Traditional methods for wildlife monitoring are inadequate. Development of new computer vision tools enables the use of images as the source of information about wildlife. Social media is the rich source of wildlife images, which come with a huge bias, thus thwarting traditional population size estimate approaches. Here, we present a new framework to take into account the social media bias when using this data source to provide wildlife population size estimates. We show that, surprisingly, this is a learnable and potentially solvable problem.
Drone strike by Khalifa Hifter's forces on south Libyan town kills at least 43, official says
TRIPOLI – A drone airstrike by eastern Libyan forces on the southern Libyan town of Murzuq has killed at least 43 people, a local official said on Monday. The attack is the second major airstrike blamed on the eastern Libyan National Army (LNA) forces loyal to Khalifa Hifter after at least 44 migrants were killed in June when a detention center in a suburb of the capital Tripoli was hit. The LNA confirmed a strike late on Sunday on Murzuq, but denied it had targeted any civilians. The LNA had also denied it had hit the detention center but acknowledged increased air strikes on the capital. The internationally recognized government based in Tripoli opposing Hifter said dozens were killed and wounded in Murzuq. Reached by telephone, Murzuq municipal council member Mohamed Omar told Reuters: "The airstrike resulted in 43 killed and 51 wounded.
Fully-automated patient-level malaria assessment on field-prepared thin blood film microscopy images, including Supplementary Information

--Malaria is a life-threatening disease affecting millions. Microscopy-based assessment of thin blood films is a standard method to (i) determine malaria species and (ii) quanti-tate high-parasitemia infections. Full automation of malaria microscopy by machine learning (ML) is a challenging task because field-prepared slides vary widely in quality and presentation, and artifacts often heavily outnumber relatively rare parasites. In this work, we describe a complete, fully-automated framework for thin film malaria analysis that applies ML methods, including convolutional neural nets (CNNs), trained on a large and diverse dataset of field-prepared thin blood films. Quanti-tation and species identification results are close to sufficiently accurate for the concrete needs of drug resistance monitoring and clinical use-cases on field-prepared samples. We focus our methods and our performance metrics on the field use-case requirements. We discuss key issues and important metrics for the application of ML methods to malaria microscopy. Index T erms --malaria, automated microscopy, deep neural networks, gradient boosted trees I. I NTRODUCTION Malaria is a mosquito-borne disease caused by Plasmodium species ( P . Manual microscopy examination of Giemsa-stained blood films is a widespread malaria diagnosis method. Key use-cases include diagnosis; species identification (ID) to guide treatment [2]; and quantitation of parasites for drug resistance studies, to track how fast a drug clears parasites from the blood. However, a lack of training, high inter-sample variability in preparation and presentation, and difficult field conditions can result in poor accuracy [3], [4]. Also, lack of trained personnel limits the number of drug resistance sentinel sites. Malaria microscopy is a difficult task for automated image-processing and machine learning (ML) systems for two reasons: Field-prepared blood films vary widely in quality and presentation; and parasites are small (with feature size close to optical limits of resolution), rare, highly variable, and easily confused with non-parasite objects (artifacts). But it is also a high-value target, due to the potential benefit for so many people, and also because automated systems have some concrete advantages: They can be widely deployed, solving the expert-training bottleneck; they can examine more blood volume per patient, reducing variability in quantitation caused by Poisson statistics; and their results are reproducible.
Intelligent Process Automation: The next wave of RPA - Suyati Technologies
We know of the impact that Robotic Process Automation (RPA) has made on multiple industries. However, RPA in itself is undergoing a transformation that is set to bring a wave of unprecedented change. This transformation is known as Intelligent Process Automation (IPA). Intelligent Process Automation is the coming together of Artificial Intelligence with new age technologies such as Natural Language Processing, Machine Learning, Computer Vision, Robotic Process Automation, Cognitive Automation and more. IPA is set to become the core of next generation operating models.
How do we build trust between humans and AI?
When she calls me, she can immediately tell if something is wrong, simply from the way I say "Hello" or "I'm fine". Like many relationships with those we hold close, my mom and I have built a level of trust to the point that she knows how I'm feeling from a simple word or phrase. But unfortunately, I, like many others in the world today, spend as much (if not more) time interacting with technology as I do with the people close to me. Yet unlike talking to my mom or a friend, the way we interact with devices is completely transactional. My cell phone can't read between the lines and understand what's really going on with me.
Innovation rush aims to help farmers, rich and poor, beat climate change
LONDON - In decades to come, African farmers may pool their money to buy small robot vehicles to weed their fields or drones that can hover to squirt a few drops of pesticide only where needed. Smartphones already allow farmers in remote areas to snap photos of sick plants, upload them and get a quick diagnosis, plus advice on treatment. Researchers also are trying to train crops like maize and wheat to produce their own nitrogen fertilizer from the air -- a trick soybeans and other legumes use -- and exploring how to make wheat and rice better at photosynthesis in very hot conditions. As warmer, wilder weather linked to climate change brings growing challenges for farmers across the globe -- and as they try to curb their own heat-trapping emissions -- a rush of innovation aimed at helping both rich and poor farmers is now converging in ways that could benefit them all, scientists say. In a hotter world, farmers share "the same problems, the same issues," said Svend Christensen, head of plant and environmental sciences at the University of Copenhagen.
Classi-Fly: Inferring Aircraft Categories from Open Data
Strohmeier, Martin, Smith, Matthew, Lenders, Vincent, Martinovic, Ivan
In recent years, air traffic communication data has become easy to access, enabling novel research in many fields. Exploiting this new data source, a wide range of applications have emerged, from weather forecasting to stock market prediction, or the collection of intelligence about military and government movements. Typically these applications require knowledge about the metadata of the aircraft, specifically its operator and the aircraft category. armasuisse Science + Technology, the R&D agency for the Swiss Armed Forces, has been developing Classi-Fly, a novel approach to obtain metadata about aircraft based on their movement patterns. We validate Classi-Fly using several hundred thousand flights collected through open source means, in conjunction with ground truth from publicly available aircraft registries containing more than two million aircraft. We show that we can obtain the correct aircraft category with an accuracy of over 88%. In cases, where no metadata is available, this approach can be used to create the data necessary for applications working with air traffic communication. Finally, we show that it is feasible to automatically detect sensitive aircraft such as police and surveillance aircraft using this method.
