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.

How Chatbots Are About To Change Communication

#artificialintelligence

At Borisov's company Progress, he uses the example of chatbots they built for hospitals, which "automate the process for patients to book doctor appointments by talking to a chatbot." These chatbots are powered by Artificial Intelligence and Natural Language Understanding, he says, meaning that "It is trained to understand different intents or conversations. "The reduction of staff for repetitive processes requiring customer support employees is the biggest promise of chatbots in the long-term," says Borisov. Many basic chatbots are built using "functional programming," Borisov explains: "Developers today can use Natural Language Processing (NLP) algorithms to extract structured data from natural language, and use this information to create more intelligent chatbots.


MIT Created an AI That Knows the Ingredients in Your Food

#artificialintelligence

Researchers gathered 1,029,720 recipes and 887,706 meal images from popular cooking websites such as All Recipes and Food.com and manually removed duplicate images as well as unwanted characters such as exclamation points or question marks. When the Pic2Recipe AI was asked to view an image of a meal, it was able to use the database to identify the correct ingredients 65 percent of the time. This is an 80 percent improvement from the 2014 Food-101 study in which Swiss researchers created an algorithm that could correctly identify a meal's ingredients from an image 50.76 percent of the time. The CSAIL research team hopes to refine Pic2Recipe so that it can not only parse more complicated meals, but also provide preparation methods for the meals.


Future Of IoT, Machine Learning, And Artificial Intelligence

#artificialintelligence

As the Internet of Things (IoT) and Artificial Intelligence (AI) grow and expand, the way companies and industries doing business and the way customer responds to the market have been changing swiftly. The way industries and customer-oriented companies are doing business using Internet of Things (IoT) and Artificial Intelligence (AI), they have come to the conclusion that AI and IoT will design and define the future and will create a trend of success or failure. According to some estimates, spending on the Healthcare IoT solutions will reach $1 trillion within one decade and will reach the stage for highly personalized, accessible, and on-time Healthcare services for everyone. The companies have access to massive customer data from their various interactions with online apps and websites are in a stage of earning millions of dollars for what they have in hand, the data.


The UK desperately needs a Radiology AI Incubator – Hugh Harvey – Medium

#artificialintelligence

In the UK academic circuit there are dozens of medical imaging researchers building algorithms on small datasets, but they lack the resources to test them on millions of images, let alone get their product into the market. What is needed is the alignment of big technology companies, the RCR and the NHS governing bodies to drive a fully collaborative vision in the field of radiology AI. We should be capitalising on the NHS as a national system, by pooling imaging data and building a nationalised imaging warehouse and technology incubator (I'd like to call this BRAIN -- British Radiology Artificial Intelligence Network). This would create a national institute for radiology in AI, capable of attracting industry partners, funding for researchers and equipment.


Must-Have Skills In The New World Of Automation and AI

International Business Times

Artificial intelligence is steadily taking up activities and jobs performed by humans these days. Unlike previous industrial ages, which forced humans to use their brains more instead of performing physical labor, the AI-based industrial age that is slowly but definitely gaining momentum might actually ease the pressure on the human brain. According to the World Bank Group, human skill sets such as ones socio-emotional interactions, higher-order cognition, basic cognition skills and technical ones might put employees in high demand. Are we looking into investing more into skills like teaching and nursing and shaping emotional intelligence better?


How Drinking Affects Your Memory

International Business Times

The study found that individuals who drank alcohol after completing a word-learning task were able to remember more of what they learned than those who did not drink alcohol. "Our research not only showed that those who drank alcohol did better when repeating the word-learning task, but that this effect was stronger among those who drank more," said Professor Celia Morgan, Medical Xpress reported. For the small study, researchers from the University of Exeter in England had 88 social drinkers complete a word-learning task. "The causes of this effect are not fully understood, but the leading explanation is that alcohol blocks the learning of new information and therefore the brain has more resources available to lay down other recently learned information into long-term memory," explained Morgan, Medical Xpress reported.


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

#artificialintelligence

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).


Artificial Intelligence in Healthcare: Medical Ethics and the Machine Revolution

#artificialintelligence

While this theme may be premature, the concern of teaching ethics and valuing human life is a relevant question for machine learning, especially in the realm of healthcare. Creating "laws" or "rules" for ethics in artificial intelligence as Elon Musk calls for is difficult in that ethical bounds are difficult to teach machines. Many companies have done extensive work in training systems that will be working with patients to learn what words mean and common patterns within patient care. When a patient asks about their symptoms they get clinically relevant information paired with their symptoms even if that patient uses non-medical language in describing their chief complaint.
