SemEval-2013 Task 4: Free Paraphrases of Noun Compounds

arXiv.org Artificial Intelligence

In this paper, we describe SemEval-2013 Task 4: the definition, the data, the evaluation and the results. The task is to capture some of the meaning of English noun compounds via paraphrasing. Given a two-word noun compound, the participating system is asked to produce an explicitly ranked list of its free-form paraphrases. The list is automatically compared and evaluated against a similarly ranked list of paraphrases proposed by human annotators, recruited and managed through Amazon's Mechanical Turk. The comparison of raw paraphrases is sensitive to syntactic and morphological variation. The "gold" ranking is based on the relative popularity of paraphrases among annotators. To make the ranking more reliable, highly similar paraphrases are grouped, so as to downplay superficial differences in syntax and morphology. Three systems participated in the task. They all beat a simple baseline on one of the two evaluation measures, but not on both measures. This shows that the task is difficult.


Meta Adaptation using Importance Weighted Demonstrations

arXiv.org Artificial Intelligence

Imitation learning has gained immense popularity because of its high sample-efficiency. However, in real-world scenarios, where the trajectory distribution of most of the tasks dynamically shifts, model fitting on continuously aggregated data alone would be futile. In some cases, the distribution shifts, so much, that it is difficult for an agent to infer the new task. We propose a novel algorithm to generalize on any related task by leveraging prior knowledge on a set of specific tasks, which involves assigning importance weights to each past demonstration. We show experiments where the robot is trained from a diversity of environmental tasks and is also able to adapt to an unseen environment, using few-shot learning. We also developed a prototype robot system to test our approach on the task of visual navigation, and experimental results obtained were able to confirm these suppositions.


Gamma-Nets: Generalizing Value Estimation over Timescale

arXiv.org Artificial Intelligence

We present $\Gamma$-nets, a method for generalizing value function estimation over timescale. By using the timescale as one of the estimator's inputs we can estimate value for arbitrary timescales. As a result, the prediction target for any timescale is available and we are free to train on multiple timescales at each timestep. Here we empirically evaluate $\Gamma$-nets in the policy evaluation setting. We first demonstrate the approach on a square wave and then on a robot arm using linear function approximation. Next, we consider the deep reinforcement learning setting using several Atari video games. Our results show that $\Gamma$-nets can be effective for predicting arbitrary timescales, with only a small cost in accuracy as compared to learning estimators for fixed timescales. $\Gamma$-nets provide a method for compactly making predictions at many timescales without requiring a priori knowledge of the task, making it a valuable contribution to ongoing work on model-based planning, representation learning, and lifelong learning algorithms.


The Collapse of Civilization May Have Already Begun

#artificialintelligence

"It is now too late to stop a future collapse of our societies because of climate change." These are not the words of a tinfoil hat-donning survivalist. This is from a paper delivered by a senior sustainability academic at a leading business school to the European Commission in Brussels, earlier this year. Before that, he delivered a similar message to a UN conference: "Climate change is now a planetary emergency posing an existential threat to humanity." In the age of climate chaos, the collapse of civilization has moved from being a fringe, taboo issue to a more mainstream concern. As the world reels under each new outbreak of crisis--record heatwaves across the Western hemisphere, devastating fires across the Amazon rainforest, the slow-moving Hurricane Dorian, severe ice melting at the poles--the question of how bad things might get, and how soon, has become increasingly urgent. The fear of collapse is evident in the framing of movements such as'Extinction Rebellion' and in resounding warnings that business-as-usual means heading toward an uninhabitable planet. But a growing number of experts not only point at the looming possibility that human civilization itself is at risk; some believe that the science shows it is already too late to prevent collapse. The outcome of the debate on this is obviously critical: it throws light on whether and how societies should adjust to this uncertain landscape. Yet this is not just a scientific debate. It also raises difficult moral questions about what kind of action is warranted to prepare for, or attempt to avoid, the worst. Scientists may disagree about the timeline of collapse, but many argue that this is entirely beside the point. While scientists and politicians quibble over timelines and half measures, or how bad it'll all be, we are losing precious time.


Within 10 Years, We'll Travel by Hyperloop, Rockets, and Avatars

#artificialintelligence

Try Hyperloop, rocket travel, and robotic avatars. Hyperloop is currently working towards 670 mph (1080 kph) passenger pods, capable of zipping us from Los Angeles to downtown Las Vegas in under 30 minutes. Rocket Travel (think SpaceX's Starship) promises to deliver you almost anywhere on the planet in under an hour. Think New York to Shanghai in 39 minutes. As 5G connectivity, hyper-realistic virtual reality, and next-gen robotics continue their exponential progress, the emergence of "robotic avatars" will all but nullify the concept of distance, replacing human travel with immediate remote telepresence.

Microsoft adds Māori to translator as New Zealand pushes to revitalize the language – TechCrunch

#artificialintelligence

The benefits of machine translation are easy to see and experience for ourselves, but those practical applications are only one part of what makes the technology valuable. Microsoft and the government of New Zealand are demonstrating the potential of translation tech to help preserve and hopefully breathe new life into the Māori language. Te reo Māori, as it is called in full, is of course the language of New Zealand's largest indigenous community. But as is common elsewhere as well, the tongue has fallen into obscurity as generations of Māori have assimilated into the dominant culture of their colonizers. Māori people make up about 15 percent of the population, and only a quarter of them speak the language, making for a grand total of 3 percent that speak te reo Māori.


5 Ways Artificial Intelligence Is Transforming Digital Pathology -

#artificialintelligence

Thanks to approvals from the Food and Drug Administration (FDA) for applications such as primary disease diagnosis, digital pathology is rapidly becoming the new standard of care. However, this advancement creates challenges that artificial intelligence could help solve. Digital pathology enables capturing pathology information, such as whole slide images (WSI), and working with it digitally using a specialized scanner. Acquiring, studying and managing data in this way allows sharing between parties on a computer or mobile device. According to experts, the global digital pathology market was worth $689.2 million in 2018.


From blue tea to avocado coffee: AI tool to help firms launch new products 'ahead of trend'

#artificialintelligence

According to Kerry Vice President Marketing & Strategy APMEA Parth Patel, Trendspotter was developed in order to both launch F&B products ahead of trend as well as to reduce the lead time for innovation by up to seven months. "Imagine, if as a branded food and beverage player you are able to launch a new product ahead of its trend. Basically, you are creating a runway for yourself and most probably you are going to be the only player, hence chances of success are high," he told FoodNavigator-Asia . "We aim to reduce the lead time for innovation and the chances of failure of new product launches, while increasing the probability of success by focusing on those trends which are emerging and not yet mainstream." The need here comes from high rates of recorded failures – a recent Nielsen study found that 85% of new product launches fail within 18 to 24 months, driving high burdens in terms of cost, time, and effort for all major F&B companies.


UK Department for Work and Pensions accelerates use of robots – Government & civil service news

#artificialintelligence

The UK's Department for Work and Pensions (DWP) is accelerating its use of automated systems to handle claims for benefits, in a move some fear will disadvantage welfare recipients. The DWP has hired nearly 1,000 new IT staff in the last 18 months, and increased spending to about £8m (US$10.3m) This new'virtual workforce' is to take over some of the jobs of humans. According to an investigation by The Guardian, which has unearthed further detail on the DWP's plans, one recent tender document requested help to build "systems that… can automatically carry out tasks without human intervention". As well as contracts with a number of multinationals, the department is working with UiPath, a New York-based firm co-founded by Daniel Dines, the world's first "bot billionaire", whose machine learning software is being deployed by the DWP to check benefit claims and detect fraud.
