Challenging robo decisions a safeguard humans may need: expert

#artificialintelligence

Colin Gavaghan says there is growing concern about the lack of transparency about decisions made by computer algorithms. Having a human in the loop won't be enough to ensure decisions made using artificial intelligence will always be fair, says an Otago University academic who is helping shaping an emerging international debate on digital rights. Computers have already been used in New Zealand to assist in parole decisions by forecasting the chances of individual prisoners reoffending, and to identify ACC claimants who might be staying on benefits longer than expected. Software has also used by the Social Development Ministry in a brief and controversial experiment to predict children at risk of abuse. But Professor Colin Gavaghan warns an explosion of interest in artificial intelligence (AI) could lead to half-baked software flooding the market which won't be good at what it is supposed to do.


As AI takes over the world, AI analytics benefits the world of business, too

#artificialintelligence

And there is certainly a place for utilizing AI machine learning in the business world. As Richard writes "it's heartening to see a New Zealand startup providing such a useful AI service to businesses. Understanding customers isn't easy since we humans tend to be emotional. Sometimes we need machines to help figure us out."


Military AI, Business VAs, And Peak Hype - Five Unmissable Stories In This Week's AI Digest

#artificialintelligence

Here's what you need to know today: Siri, Cortana, and Alexa could soon have to move over in the office, following the release of Cisco's AI assistant for business. Yesterday saw the first live demo of Cisco's Spark virtual assistant, first announced back in November 2017, at a Cisco Live event in Melbourne, Australia. Cisco senior VP and general manager of applications Rowan Trollope told the event that "existing voice assistants that have traction – none of them were built for business. They were built for the consumer domain. That is a totally different domain space to the one we are interested in."


Fast Cosmic Web Simulations with Generative Adversarial Networks

arXiv.org Machine Learning

Dark matter in the universe evolves through gravity to form a complex network of halos, filaments, sheets and voids, that is known as the cosmic web. Computational models of the underlying physical processes, such as classical N-body simulations, are extremely resource intensive, as they track the action of gravity in an expanding universe using billions of particles as tracers of the cosmic matter distribution. Therefore, upcoming cosmology experiments will face a computational bottleneck that may limit the exploitation of their full scientific potential. To address this challenge, we demonstrate the application of a machine learning technique called Generative Adversarial Networks (GAN) to learn models that can efficiently generate new, physically realistic realizations of the cosmic web. Our training set is a small, representative sample of 2D image snapshots from N-body simulations of size 500 and 100 Mpc. We show that the GAN-produced results are qualitatively and quantitatively very similar to the originals. Generation of a new cosmic web realization with a GAN takes a fraction of a second, compared to the many hours needed by the N-body technique. We anticipate that GANs will therefore play an important role in providing extremely fast and precise simulations of cosmic web in the era of large cosmological surveys, such as Euclid and LSST.


Vic MPs to examine artificial intelligence

"This is something that can provide us with huge opportunities within our industry development. "Yes, people will be fearful of it, but we should be learning to embrace that change." The group, modelled on the UK version, will examine the economic and social effects of artificial intelligence.


A Multi-Objective Deep Reinforcement Learning Framework

arXiv.org Machine Learning

This paper presents a new multi-objective deep reinforcement learning (MODRL) framework based on deep Q-networks. We propose linear and non-linear methods to develop the MODRL framework that includes both single-policy and multi-policy strategies. The experimental results on a deep sea treasure environment indicate that the proposed approach is able to converge to the optimal Pareto solutions. The proposed framework is generic, which allows implementation of different deep reinforcement learning algorithms in various complex environments. Details of the framework implementation can be referred to http://www.deakin.edu.au/~thanhthi/drl.htm.


Rambo and the machine learning models helping Sportsbet up its games

#artificialintelligence

A Netflix-style recommendation engine on steroids, a Google AdWords beater and a souped-up game simulator are among a number of machine learning models at work behind the scenes at online bookmaker Sportsbet, the company has revealed. "Our goal is to improve the customer experience at every customer interaction," said Tony Gruebner, the company's general manager, analytics, insights and modelling. Speaking at the Gartner Data and Analytics Summit in Sydney last week, Gruebner explained: "One of the best ways of doing that is to build great data products utilising the company's wealth of data – which is exponentially growing – and also machine learning and artificial intelligence capabilities." Sportsbet helped make gambling mainstream in Australia, was bought out by Paddy Power in 2010 and quickly became the country's biggest corporate online bookmaker, a title it still holds. It makes around 1.7 billion price updates, offers punters 11 million markets and takes 240 million bets every year.


19 Data Science Tools for people who aren't so good at Programming

@machinelearnbot

This list of Data Science tools for people who aren't so good at Programming was compiled by Aarshay Jain, from Analytics Vidhya. Programming is an integral part of data science. Among other things, it is considered that a mind which understands programming logic, loops, and functions has higher chances of becoming a successful data scientist. So, what about people who never studied programming subject in their school or college? RM covers the entire life-cycle of prediction modeling, starting from data preparation to model building and finally validation and deployment.


How Employees Feel About AI in the Workplace

#artificialintelligence

Four out of five employees see significant opportunity for artificial intelligence (AI) to create a more engaging and empowering workplace experience, yet employees admit a lack of transparency from their employers is a primary driver of fear and concern. This is according to a worldwide survey of nearly 3,000 employees across eight nations conducted by The Workforce Institute at Kronos Incorporated. "The Engaging Opportunity: Working Smarter with AI" survey conducted with Coleman Parkes Research explores how employees – both hourly and salaried from a variety of industries in Australia, Canada, France, Germany, Mexico, New Zealand, the United Kingdom and the U.S. – believe emerging technologies should be used to improve the future of work. Employees around the world say they will embrace AI to make work easier and fairer. A lack of communication leaves employees feeling apprehensive.


Get smart: making our cities great places to live

#artificialintelligence

To remain livable and economically competitive, rapidly growing cities need to embrace high-tech solutions to solve their many practical problems. However, how willing are citizens to sacrifice their privacy for the benefits of smart cities, and can government regulations keep up with new tech? This places a significant burden on vital infrastructure, such as transport, housing, energy supply, health care and waste management. Livability in the megacities of tomorrow will largely be determined by the smart solutions being developed today. The term "smart city" is popular among policymakers worldwide.
