A recent example of such work is the ICLR 2016 paper "Learning to Diagnose with LSTM Recurrent Neural Networks" (of which Mr. Kale is a joint first author in his capacity as a PhD candidate at the USC Information Science Institute). In it, the authors trained a LSTM RNN or LSTM, to classify acute care diseases such as respiratory distress in critically ill children. The RNN (and the more complex LSTM RNN) is a neural net architecture with recurrent connections between hidden states, giving it a form of persistent state (or "memory") across sequential inputs. These connections enable RNNs to detect relationships not only between inputs, e.g., heart rate and blood pressure, but also over time, e.g., between a patient's state at time of admission and later in an ICU stay. This makes it especially well-suited to health problems, which often involve modeling changes over time.


How Disabled Students Benefit From Assistive Technology In Classrooms

International Business Times

Technology has modernized the system of education for students with various disabilities, making it easier for them to keep up with academic curriculums and even compete with their peers in classrooms. According to Open Colleges, most of the common disabilities can be categorized into any of the following classification -- Physical (students using wheelchairs, prosthetic limbs, or dealing with diseases such as muscular dystrophy, Lou Gehrig's disease, multiple sclerosis, etc), Sensory (students lacking in normal visual, hearing or speaking abilities), Cognitive (students with weaknesses when it comes to memory, self-expression, information processing, and other learning disabilities), Psychiatric (students may suffer from an array of challenges, ranging from social phobias, bipolar and/or other personality disorders), Health-related (students who have chronic illnesses like cancer, diabetes or epilepsy) A Palestinian child reads braille during a class at Al-Nour, which translates'we have seen,' Rehabilitation Center for the Visually Impaired, in Gaza City, Gaza Strip, May 7, 2006. Students who suffer from any form of disability might find it difficult to attend classes regularly, keep up with everything that is being taught and compete at the same level with children who are not plagued by the same impairments that they have. These students often need some extra assistance when it comes to performing academically. One of the best forms of assistance in today's times is the gift of technology.


A statistical fix for the replication crisis in science

#artificialintelligence

In a trial of a new drug to cure cancer, 44 percent of 50 patients achieved remission after treatment. Without the drug, only 32 percent of previous patients did the same. The new treatment sounds promising, but is it better than the standard? That question is difficult, so statisticians tend to answer a different question. They look at their results and compute something called a p-value.


3 Industries That Will Be Transformed By AI, Machine Learning And Big Data In The Next Decade

@machinelearnbot

Historically, when new technologies become easier to use, they transform industries. That's what's happening with artificial intelligence and big data; as the barriers to implementation disappear (cost, computing power, etc.), more and more industries will put the technologies into use, and more and more startups will appear with new ideas of how to disrupt the status quo with these technologies. By my predictions, the AI revolution isn't coming, it's already here, and we'll see it first in a few key sectors. Most people agree that healthcare is broken, and many startups believe that the biggest answer is putting the power back in the hands of the patient. We're all carrying the equivalent of Star Trek's tricorder around in our pockets (or an early version, at any rate) and smartphones and other smart devices will continue to advance and integrate with AI and big data to allow individuals to self-diagnose.


The Troubled Marriage of Brains and Computers

Wall Street Journal

That moment was the culmination of two decades of work in brain-machine interface technology, a research field I pioneered with my colleagues at Duke University. Early experiments involved rats and monkeys moving levers, robots and avatar bodies using their thoughts. My colleagues and I believe that we can apply what we've learned about neuroplasticity--the ability of the brain to change over time--to a range of neurological diseases, including Parkinson's disease, epilepsy, stroke, cerebral palsy and even autism. Scientists from university labs to Silicon Valley are working on two additional ideas conceived in my lab: connecting brains to form a network, or brainet, and developing a communication method that lets people message one another directly brain-to-brain. Once brains are connected they could become a hackable system in which the thoughts and actions of connected individuals can be accessed and manipulated.


What Does It Mean to Be Intelligent?

#artificialintelligence

The Singularity is a term you'll find in science and in science fiction. It was coined by mathematician John von Neumann to define a theoretical moment when the artificial intelligence of computers surpasses the capacity of the human brain. The term is borrowed from physics and quantum mechanics, where the term gravitational singularity is used in the study of black holes. These events are all considered singular because we are unable to predict what happens next; the disruptive degree of change associated with the event is simply too great for our current body of knowledge. While we are far from attaining the goal of artificial intelligence, there was a brief flurry of excitement recently when a computer passed the Turing Test, to mixed reviews.


The Better World Tour comes home to Boston

MIT News

On Sept. 28, the Better World tour was back in MIT's own neighborhood, at the Boch Center Wang Theatre in downtown Boston. More than 1,000 MIT alumni and friends were in attendance to celebrate the MIT Campaign for a Better World, a galvanizing effort that has gathered momentum and participation since the its public launch in May 2016, at events around the world. Guests who might have thought that listening would be their only role in the program were in for a pleasant surprise. Eran Egozy '95, MNG '95, MIT professor of the practice in music technology, a cofounder of Harmonix Music Systems, and the creator of "Guitar Hero," kicked off the evening by inviting the audience to join him in a classic MIT experiment. Using a new music application called "Tutti" (Italian for "together") and audience members' cell phones, Egozy transformed the audience into an orchestra for a rendition of "Engineered Engineers," a composition created for the event by Evan Ziporyn, the Kenan Sahin Distinguished Professor and Music and Theater Arts chair.


AI-powered pathology is transforming cancer care

#artificialintelligence

In May, Sundar Pichai, CEO of Google, discussed AI applications for digital pathology in his keynote speech to an audience of millions at Google's annual I/O event. Five weeks earlier, the FDA announced it had approved the first whole slide imaging system for primary diagnostic use in pathology. Both events point to the future of pathology and laboratory medicine: Software will soon dominate. Over the past 20 years, software has taken over the world. Retail was dominated by Amazon, Netflix put Blockbuster out of business, and Uber used software to take over the taxi industry.


Can We Still Rely On Science Done By Sexual Harassers?

WIRED

The pandemic of sexual harassment and abuse--you saw its prevalence in the hashtag #metoo on social media in the past weeks--isn't confined to Harvey Weinstein's casting couches. Decades of harassment by a big shot producer put famous faces on the problem, but whisper networks in every field have grappled with it forever. Last summer, the story was women in Silicon Valley. Earthquakes of this magnitude are never any fun for people atop shifting tectonic plates. But the new world they create can be a better one.


Our 'selfish brain' wins when competing with muscle power

Daily Mail

Human brains take a lot of energy to run, and keeping our sophisticated grey matter going comes at an evolutionary cost. Researchers found a trade-off occurs when we have to think fast and work hard at the same time - and our'selfish brain' is always prioritised over the rest of our body. Our ability to allocate more glucose to the brain could have helped our species survive and thrive by becoming quick thinkers, researchers found. Researchers found a trade-off occurs when we have to think fast and work hard at the same time - and our'selfish brain' is less affected than our physical capacity (stock image) The rowers performed two separate tasks: one memory, a three minute word recall test; and one physical, a three minute power test on a rowing machine. They then performed both tasks at once, with individual scores compared to those from previous tests.
