Why AI is still terrible at spotting violence online

#artificialintelligence

But with a huge volume of posts popping up on these sites each day, it's difficult for even this combination of people and machines to keep up. AI still has a long way to go before it can reliably detect hate speech or violence online. Machine learning, the AI technique tech companies depend on to find unsavory content, figures out how to spot patterns in reams of data; it can identify offensive language, videos, or pictures in specific contexts. That's because these kinds of posts follow patterns on which AI can be trained. For example, if you give a machine-learning algorithm plenty of images of guns or written religious slurs, it can learn to spot those things in other images and text.


New Zealand farmers have a new tool for herding sheep: drones that bark like dogs

#artificialintelligence

You have probably read about robots replacing human labor as a new era of automation takes root in one industry after another. But a new report suggests humans are not the only ones who might lose their jobs. In New Zealand, farmers are using drones to herd and monitor livestock, assuming a job that highly intelligent dogs have held for more than a century. The robots have not replaced the dogs entirely, Radio New Zealand reports, but they have appropriated one of the animal's most potent tools: barking. The DJI Mavic Enterprise, a $3,500 drone favored by farmers, has a feature that lets the machine record sounds and play them over a loud speaker, giving the machine the ability to mimic its canine counterparts.


Why AI is still terrible at spotting violence online

#artificialintelligence

Artificial intelligence can identify people in pictures, find the next TV series you should binge watch on Netflix, and even drive a car. But on Friday, when a suspected terrorist in New Zealand streamed live video to Facebook of a mass murder, the technology was of no help. The gruesome broadcast went on for at least 17 minutes until New Zealand police reported it to the social network. Recordings of the video and related posts about it rocketed across social media while companies tried to keep up. Why can't AI, which is already used by major social networks to help moderate the status updates, photos, and videos users upload, simply be deployed in greater measures to remove such violence as swiftly as it appears? A big reason is that whether it's hateful written posts, pornography, or violent images or videos, artificial intelligence still isn't great at spotting objectional content online.


Do new technologies take ethics out of healthcare?

#artificialintelligence

As such, even though these technologies bring huge potential and opportunities, they still need to be closely monitored. The University of New South Wales Research Ethics and Compliance Support Director Dr Ted Rohr told HITNA that issues around ethics arise when healthcare access data from medical records for research, for example. "Ethics is all about deciding whether the use of technology is appropriate and is used for public good. For example, AI has its positives, but it can be misused. So, having an ethical framework allows the proper use of medical databases for research and experiments with patients using devices," he said.


Toby Walsh Discusses AI and the Future of Work โ€“ Trust This Robot

The discussion took place today at the Conference of Major Superannuation Funds put on by the Australian Institute of Superannuation Trustees. Walsh covers everything from myths about AI to Ethics and Artificial Intelligence.


The rise of machine learning in astronomy

#artificialintelligence

When mapping the universe, it pays to have some smart programming. Experts share how machine learning is changing the future of astronomy. Astronomy is one of the oldest sciences and the first science to incorporate maths and geometry. It sits at the centre of humankind's search for its place in the universe. As we delve deeper into the space surrounding our planet, the tools we use become more complex.


Artificial intelligence is going to control on-demand bus services in Japan

#artificialintelligence

The Mitsubishi Corporation has set up a joint venture company that will use artificial intelligence (AI) to control on-demand bus services in Japan. The new company, called Next Mobility, has been established by Mitsubishi and the Nishi-Nippon Railroad Company, a major Japanese bus operator. The joint venture will start a one-year trial in April at Island City, in the Higashi-ward of Fukuoka City. In a statement Wednesday, Mitsubishi said that the AI would be used to automatically generate routes, in real time, based on passenger requests that are made through a smartphone app. Deep learning will be used to collate "operational data" on both traffic conditions and passenger destinations.


Teaching with IMPACT

arXiv.org Machine Learning

Like many problems in AI in their general form, supervised learning is computationally intractable. We hypothesize that an important reason humans can learn highly complex and varied concepts, in spite of the computational difficulty, is that they benefit tremendously from experienced and insightful teachers. This paper proposes a new learning framework that provides a role for a knowledgeable, benevolent teacher to guide the process of learning a target concept in a series of "curricular" phases or rounds. In each round, the teacher's role is to act as a moderator, exposing the learner to a subset of the available training data to move it closer to mastering the target concept. Via both theoretical and empirical evidence, we argue that this framework enables simple, efficient learners to acquire very complex concepts from examples. In particular, we provide multiple examples of concept classes that are known to be unlearnable in the standard PAC setting along with provably efficient algorithms for learning them in our extended setting. A key focus of our work is the ability to learn complex concepts on top of simpler, previously learned, concepts---a direction with the potential of creating more competent artificial agents.


Incremental Learning of Discrete Planning Domains from Continuous Perceptions

arXiv.org Artificial Intelligence

We propose a framework for learning discrete deterministic planning domains. In this framework, an agent learns the domain by observing the action effects through continuous features that describe the state of the environment after the execution of each action. Besides, the agent learns its perception function, i.e., a probabilistic mapping between state variables and sensor data represented as a vector of continuous random variables called perception variables. We define an algorithm that updates the planning domain and the perception function by (i) introducing new states, either by extending the possible values of state variables, or by weakening their constraints; (ii) adapts the perception function to fit the observed data (iii) adapts the transition function on the basis of the executed actions and the effects observed via the perception function. The framework is able to deal with exogenous events that happen in the environment.


'Too complex to fly'? Trump riff on planes shows aversion to technological change and science

Los Angeles Times

He has demanded "goddamned steam" to power the Navy's aircraft carriers and prefers a wall to drones and other technology to secure the country's southern border. He has rejected the scientific consensus on climate change and repeatedly, wrongly, pointed to occasional wintry weather as proof that he's right. And this week, amid a safety scare involving Boeing's 737 MAX 8 and MAX 9 airplanes, President Trump complained that modern jets are "too complex to fly." He added: "I see it all the time in many products. Always seeking to go one unnecessary step further, when often old and simpler is far better."
