Mental health chatbot Woebot can help fight depression

Daily Mail

It runs through Facebook Messenger, and acts as a personal therapist to help address users' mental health challenges, including depression and anxiety. Within the chat, Woebot uses artificial intelligence to create natural, personalised and human-like conversations and offer emotional support to users.

Soft Robotic Exosuit Can Help Stroke Patients

IEEE Spectrum Robotics Channel

Soft wearable robotic exosuits can help patients walk after strokes, a new study finds. However, while the rigid nature of most exoskeletons can help them provide large amounts of assistance for patients who could not otherwise walk, they may not be suitable for people who have some capacity to walk on their own, as they can restrict natural movement, Walsh says. "By providing a small amount of assistance, our soft exosuit could provide significant benefits for people who retain some ability to walk, such as most stroke survivors, and allow them to move more naturally than they could with a more rigid system," Walsh says. The scientists are now planning to see whether continued use of this soft exosuit can help stroke patients learn how to walk better without the device, Walsh says.

2017 Data Science Bowl, Predicting Lung Cancer: 2nd Place Solution Write-up, Daniel Hammack and Julian de Wit


Julian and I independently wrote summaries of our solution to the 2017 Data Science Bowl. A tricky detail that I found reading the LUNA competition is that different CT machines will produce scans with different sampling rates in the 3rd dimension. Here's an example of a malignant nodule (highlighted in blue): Anyway, the LUNA16 dataset had some very crucial information - the locations in the LUNA CT scans of 1200 nodules. It's the reason that I am able to build models on only 1200 samples (nodules) and have them work very well (normal computer vision datasets have 10,000 - 10,000,000 images).

IIT researchers turn to Artificial Intelligence for identifying cancer


A team of experts from IIT-Kharagpur (IIT-Kgp) and Tata Medical Centre (TMC), Kolkata, has devised a computer-assisted model they say can automatically grade breast cancer aggressiveness, even in remote settings, providing fresh impetus to Artificial Intelligence-based medical technology in India. It seeks to reduce human error in identifying breast cancer of various levels of aggressiveness to assist in distinguishing normal and low and higher risk malignant tumours. The team has tapped into deep learning, a form of AI concerned with algorithms inspired by the structure and function of the brain called artificial neural networks. The application revolves around a protein (or marker) called Ki-67 which is used to calculate an index that groups cancers in the "low" or "high" aggressiveness groups.

How Artificial Intelligence is Transforming Modern Healthcare


To illustrate, consider Face2Gene phenotyping applications that use face recognition and machine learning to help healthcare providers in identifying rare genetic disorders. The technology innovator recently launched an AI powered Autism Test which allows providers to use eye tracking technology to identify early stages of ASD (Autism Spectrum Disorder) in children aged from 12 to 40 months. The data helps physicians identify key information in patient records and explore treatment options to create more informed treatment plans for patients. We also custom designed an algorithm with the help of Emory's Medical Researchers & Doctors for a cloud based research web application, that mimics early stage AI bots, for Emory University.

28 Best Quotes About Artificial Intelligence


When it comes to the possibilities and possible perils of artificial intelligence (AI), learning and reasoning by machines without the intervention of humans, there are lots of opinions out there. "Anything that could give rise to smarter-than-human intelligence--in the form of Artificial Intelligence, brain-computer interfaces, or neuroscience-based human intelligence enhancement - wins hands down beyond contest as doing the most to change the world. Follow that out further to, say, 2045, we will have multiplied the intelligence, the human biological machine intelligence of our civilization a billion-fold." It's really an attempt to understand human intelligence and human cognition."

This is for you, Elon Musk: 5 threats to humanity greater than artificial intelligence


Sea levels are already rising, and if nations around the world continue on emitting greenhouse gases without greatly cutting emissions, that sea level rise could be devastating. Nuclear war could kill millions and alter the Earth's climate, making parts of our planet uninhabitable. According to a 2016 report, outbreaks of infectious diseases in the future pose a major risk to human life and world economies. The largest refugee crisis since World War II is currently taking place because of rampant inequality, religious strife, armed conflict, discrimination, and the search for better lives in the West.

Analytics Unwound: A Guide For The Rest Of Us


Knowing the historical statistical performance, the manager may choose to replace the current pitcher with someone who has better historical performance against the batter. A study recently published in the journal Nature documents how Stanford researchers developed a machine learning algorithm to detect potential cases of skin cancer. Put simply, good predictive analytics require a large sampling of data to work well. Analyzing historic data to predict future outcomes only works if the past is truly representative of the future.

Artificial intelligence helps stroke patients walk again


The research comes from the Center for Neuroprosthetics and Brain Mind Institute, School of Life Sciences, Swiss Federal Institute of Technology Lausanne (EPFL), Lausanne, Switzerland. The regathers behind the development are hopeful it will lead to better outcomes for patients undergoing rehabilitation following incidences like a stroke or a spinal cord injury or strokes. READ MORE: Mayo Clinic's new startup to tackle diseases using AI Recovery plans for spinal cord injuries and strokes typically require usually many hours of supported walking, using devices like treadmills, with the walking aid pre-programmed by a medic to provide a steady pace. The new development has been described in the journal Science Translational Medicine, with the research paper headed "A multidirectional gravity-assist algorithm that enhances locomotor control in patients with stroke or spinal cord injury."

Lasers reactivate 'lost' memories in mice with Alzheimer's

New Scientist

They genetically engineered mice with neurons that glow yellow when activated during memory storage, and red when activated during memory recall. But in the Alzheimer's mice, different cells glowed red during recall, suggesting that they were calling up the wrong memories. Using a genetic engineering technique called optogenetics, Denny's team went on to reactivate the lemon-shock memory in the Alzheimer's mice. The next step will be to confirm that the same memory storage and retrieval mechanisms exist in people with Alzheimer's disease, because mouse models do not perfectly reflect the condition in humans, says Martins.
