An algorithm customizes exoskeletons to fit a person's needs

Engadget

After all, a powered exoskeleton could change the lives of people who have mobility issues, whether due to age, injury or disease. Adapting them to individual humans is a difficult and time-consuming process. Rather than calibrate the device once and use it on all the participants, though, the researchers had the participants walk on a treadmill while the powered exoskeleton helped. Not only is this genetic algorithm important for creating exoskeletons that can fit a wider number of people, but it also hints that we may be able to create more complex assistive devices.


Take 5: How Humans Benefit as Machines Get Smarter

#artificialintelligence

In a recent study, Kellogg's Eli Finkel and colleagues had participants share a difficult personal story to a robot named Travis. When Travis reacted by moving and displaying supportive text, participants rated it as more social and competent. In a recent podcast, Ferrucci describes a future where humans and computers grow up together. The team found that traders made less lucrative trades when they were in a highly emotional state or a low emotional state.


In the General AI Challenge, Teams Compete for $5 Million

IEEE Spectrum Robotics Channel

Rosa recently took steps to scale up the research on general AI by founding the AI Roadmap Institute and launching the General AI Challenge. In some rounds, participants will be tasked with designing algorithms and programming AI agents. The Challenge kicked off on 15 February with a six-month "warm-up" round dedicated to building gradually learning AI agents. The tasks were specifically designed to test gradual learning potential, so they can serve as guidance for the developers.


31 Must Know Stats About Mobile Voice Usage Trends

We included in the survey a block of 10 questions focused on understanding how perceived social pressure impacts people's willingness to use voice commands with their smartphones. It is also interesting to see the impact of the respondent's age on their propensity to use voice commands: In most venues, there doesn't appear to be much difference, but when you get to more public areas, such as at a restaurant with friends, at the gym, in a public restroom, or in a theater, there is a definite tendency for those under 24 to use voice commands quite a bit more than the other age groups (51.6% vs. 38.6% The willingness of those with an income over $100K to use voice commands with their devices in public places, as compared to other income categories is startling! Single males also skew high for using voice commands to play music at 54% vs. 38.6% Those with high income are more likely to get annoyed by people using voice commands with their phone in public (50.8% vs. 41.8% for all responses), but in stark contrast they're also far more likely to do it (42.5% vs. 26.9% Note that 65.9% of women use spoken commands to text, where 54.6% of men do so. Most people agree or strongly agree that voice commands make their smartphone easier to use, with men coming in at 63.8% and women at 56%.


AI could predict how much time people have left to live by analyzing body scans

#artificialintelligence

For the study, researchers used a machine learning algorithm to analyze routine chest CT scans from 48 adults, all of whom were over 60 years of age. The most immediate application of this AI technology is that it could theoretically analyze more routine chest CT scan data and provide risk calculations without a human expert taking the time to go through each scan. "Our research opens new avenues for the application of artificial intelligence technology in medical image analysis, and could offer new hope for the early detection of serious illness, requiring specific medical interventions." The basic idea behind precision medicine is that large quantities of health data can be analyzed to determine how small differences between people affect their health outcomes.


Study will ask 10,000 New Yorkers to share life's data

Daily Mail

The study leaders aim to recruit 10,000 New Yorkers interested in advancing science by sharing a range of personal information, from cellphone locations and credit-card swipes to blood samples and life-changing events. Researchers hope the results will illuminate the interplay between health, behavior and circumstances, potentially shedding new light on conditions ranging from asthma to Alzheimer's disease.

Facebook's Just Revealed That Its Chatbots Can Negotiate as Well as Humans

#artificialintelligence

Over time, the bots learned to go beyond simply mimicking humans and instead became more unpredictable with their responses. To test the model's effectiveness, Facebook created scenarios with a hypothetical set of objects. Facebook used an "end-to-end" training model, which means the process could be altered to give the algorithm other goals similar to the one in the study. In an email, Dhruv Batra, a Facebook visiting researcher who worked on the project and also teaches computer science at the Georgia Institute of Technology, told Inc. that Facebook doesn't have any plans to implement the technology into its product yet.


Open Innovation and Crowdsourcing in Machine Learning – Getting premium value out of data

#artificialintelligence

In fact, this is not the first time we observed this kind of results: every time we ran a data challenge using RAMP (rapid analytics and model prototyping) platform, major improvements have been made over the initial solution. And model development in data science is a textbook problem solving (search & optimisation) task in an infinite solution space. Thus, RAMP is perfectly suited to business contexts where prediction errors immediately incur value loss.

Can A Chatbot Solve USA's Physical Inactivity Problem?

#artificialintelligence

Unfortunately, not many have the headspace to stay engaged with apps and consistently put in personal fitness information, diets or design workout plans. The chatbot did not only help participants to stay consistent with their workout routine but participants were also able to use the bot for a variety of other physical activities (e.g. Motivation is dramatically increased with a consistent accountability partner who reminds the user of their personal goal. Motivational content helps the user feel inspired and creates an urgency to stay persistent with personal workout goals.


Kaggle Master (IT Best Kept Secret Is Optimization)

#artificialintelligence

I entered that competition to learn about natural language processing (NLP), a domain entirely unknown to me at the start of the competition. The test set is split into a public test set, and a private test set. Then the test set error of the final chosen model will underestimate the true test error, sometimes substantially. Kaggle public test set plays the role of the validation set, while the Kaggle private test set plays the role of the test set.
