Scientists turn ALBATROSSES into surveillance drones to help track illegal fishing boats

Daily Mail - Science & tech

A team of researchers from the University of La Rochelle in France have converted albatrosses into de facto surveillance drones as part of a project to gather data on illegal fishing boats in the South Pacific and Indian Ocean. The team traveled to popular albatross nesting locations at Amsterdam Island and Kerguelen Island in the Indian Ocean north of Antarctica, and attached small sensors to 169 albatrosses in a procedure that took about 10 minutes per bird. The sensors weigh 65 grams, or around a seventh of a pound, and were equipped with a GPS receiver, a radar antenna, and a satellite communications monitor to track various boat communication systems. The devices were each powered by a small lithium battery that maintains a charge through a small solar panel, according to a report from ArsTechnica. The albatrosses covered more than 18 million square miles between East Africa and New Zealand, gathering data from more than 600,000 GPS locations.


An Implicit Attention Mechanism for Deep Learning Pedestrian Re-identification Frameworks

arXiv.org Machine Learning

Attention is defined as the preparedness for the mental selection of certain aspects in a physical environment. In the computer vision domain, this mechanism is of most interest, as it helps to define the segments of an image/video that are critical for obtaining a specific decision. This paper introduces one 'implicit' attentional mechanism for deep learning frameworks, that provides simultaneously: 1) masks-free; and 2) foreground-focused samples for the inference phase. The main idea is to generate synthetic data composed of interleaved segments from the original learning set, while using class information only from specific segments. During the learning phase, the newly generated samples feed the network, keeping their label exclusively consistent with the identity from where the region-of-interest was cropped. Hence, as the model receives images of each identity with inconsistent unwanted areas, it naturally pays the most attention to the label consistent consistent regions, which we observed to be equivalent to learn an effective receptive field. During the test phase, samples are provided without any mask, and the network naturally disregards the detrimental information, which is the insight for the observed improvements in performance. As a proof-of-concept, we consider the challenging problem of pedestrian re-identification and compare the effectiveness of our solution to the state-of-the-art techniques in the well known Richly Annotated Pedestrian (RAP) dataset.

Improving the Detection of Burnt Areas in Remote Sensing using Hyper-features Evolved by M3GP

arXiv.org Machine Learning

--One problem found when working with satellite images is the radiometric variations across the image and different images. Intending to improve remote sensing models for the classification of burnt areas, we set two objectives. The first is to understand the relationship between feature spaces and the predictive ability of the models, allowing us to explain the differences between learning and generalization when training and testing in different datasets. We find that training on datasets built from more than one image provides models that generalize better . These results are explained by visualizing the dispersion of values on the feature space. The second objective is to evolve hyper-features that improve the performance of different classifiers on a variety of test sets. We find the hyper-features to be beneficial, and obtain the best models with XGBoost, even if the hyper-features are optimized for a different method. Deforestation has serious implications on biodiversity, on rural communities that depend on forests for survival, and on greenhouse gas emissions that drive the global climate. The machine learning (ML) community can help by providing predictive models that, after learning from a small sample of an image, can automatically classify the whole image. Although previous ML work in forest monitoring has shown good results, the predictive models are often applied on the same location where they were learnt, i.e., the models are trained and tested in samples from the same dataset (e.g., [1]) or time series from the same area (e.g., [2]).


A Review of Personality in Human Robot Interactions

arXiv.org Artificial Intelligence

Personality has been identified as a vital factor in understanding the quality of human robot interactions. Despite this the research in this area remains fragmented and lacks a coherent framework. This makes it difficult to understand what we know and identify what we do not. As a result our knowledge of personality in human robot interactions has not kept pace with the deployment of robots in organizations or in our broader society. To address this shortcoming, this paper reviews 83 articles and 84 separate studies to assess the current state of human robot personality research. This review: (1) highlights major thematic research areas, (2) identifies gaps in the literature, (3) derives and presents major conclusions from the literature and (4) offers guidance for future research.


Robot kayaks found the basin of an Alaskan glacier is melting 100 TIMES faster than models showed

Daily Mail - Science & tech

Seaborne robots have made a startling discovery beneath a 20-mile glacier in Alaska. The technology found the massive rivers of ice may be melting under the LeConte Glacier much faster than previously thought. Scientists programmed autonomous kayaks to swim near the icy cliffs of the glacier to measure the'ambient meltwater intrusions', which shows how much fresh water is flowing into the ocean from underneath the glacier. The study found ambient melting was 100 times higher than models had estimated. This is the first time experts have been able to analyze plumes of meltwater - the water released when snow or ice melts, where glaciers meet the ocean- because the feat is far too dangerous for ships due to falling ice of slabs from the glacier.


Silicon Valley's cocaine problem shaped our racist tech

The Guardian

If ever there was a white paradise, it was Silicon Valley in the 1980s. We called them geniuses and wizards. Industry titans, and even a few free-thinking hippies who believed they were gods, powerful enough to shape technology to their will. This white cast of characters populated the world's largest high tech hub at a rate of nearly 75%. Absorbed 80% of the area's generated income.

2020 will be the year of delivering digital transformation with AI: Ramco CEO

#artificialintelligence

What are the key technology areas Ramco Systems will be focusing on in 2020? With this, Ramco focused on utilizing AI and ML-based algorithms to help organisations match the needs of changing business landscape. Our focus was on moving from Passive ERP (enterprise resource planning) to an Active ERP era, where systems could alert users on anomalies in data; reduce data entry by defaulting values or even pre-populating fields based on historical data through Smart Fill phrases, and so on. We have been leveraging behavioural analysis and prediction to reduce data entry and train the model to arrive at quick predictions. Also, with voice and chatbots becoming mainstream for customer/ employee engagement, UIs (user interfaces) have become passé, as we are witnessing users carry out transactions by chatting with the bot.

Entrepreneur and investor Peter Diamandis predicts that the future of shopping will be "always on", thanks to ubiquitous augmented reality. Artificial intelligence is in position to streamline and personalise the process, while virtual reality shopping can be successful if it creates a more social experience. Brands should prepare for far more data collection by asking the right questions and using AI to correlate more details. SAN FRANCISCO-- Here's the future of shopping, as Silicon Valley entrepreneur and investor Peter Diamandis sees it: augmented reality glasses will present an "always-on" shopping mode, artificially intelligent digital assistants will know your taste better than you and clothing will be made exactly to your measurements. And it could happen faster than one might think, he says.


Black-Box Saliency Map Generation Using Bayesian Optimisation

arXiv.org Artificial Intelligence

Anna Sergeevna Bosman Department of Computer Science University of Pretoria Pretoria, South Africa anna.bosman@up.ac.za Abstract --Saliency maps are often used in computer vision to provide intuitive interpretations of what input regions a model has used to produce a specific prediction. A number of approaches to saliency map generation are available, but most require access to model parameters. This work proposes an approach for saliency map generation for black-box models, where no access to model parameters is available, using a Bayesian optimisation sampling method. The approach aims to find the global salient image region responsible for a particular (black-box) model's prediction. This is achieved by a sampling-based approach to model perturbations that seeks to localise salient regions of an image to the black-box model. Results show that the proposed approach to saliency map generation outperforms grid-based perturbation approaches, and performs similarly to gradient-based approaches which require access to model parameters. I NTRODUCTION Deep learning (DL) techniques have become a standard approach in computer vision. Specifically, the convolutional neural network (CNN) architecture has shown exceptional performance, achieving results comparable to human performance on image recognition tasks [1]-[3]. As a result, the CNN models are often deployed in real life as efficient black-box tools.
