Dosis Survey: Large Majority of Patients Confident About Personalized Medicine
Research from health technology pioneer Dosis (@dosisinc) suggests that a large majority (85%) of people believe personalized medicine can enhance care delivery. Dosis, a personalized dosing platform focused on chronic disease management, surveyed more than 1,000 people, and found that nearly 80% of respondents think personalized medicine should become the standard of care for everyone.

RSIP Vision Announces New Tool for Sports Medicine Applications, Enabling Automated Assessment of Cartilage Damage
RSIP Vision (@RSIPvision), a clinically proven company in real-world AI solutions for medical image analysis, announced a new articular cartilage segmentation tool that delivers accurate, non-invasive and automatic assessment of chondral lesions in MRI scans. This new software module enables quick, precise, deep learning-based segmentation of joint cartilage from MRI scans of hips, knees, and ankles. RSIP Vision’s advanced medical imaging algorithms provide accurate measurement of the location, geometry and boundaries of osteochondral lesions in MRI images, which enable the physician to easily evaluate the extent of the damage, select the appropriate treatment and assess its efficacy.

Screening for Dementia with Artificial Intelligence
With the support of a new grant worth $3.9 million, Michigan State University (@MSUnews) researchers are developing technology that scans speech and vocabulary patterns to catch early signs of Alzheimer’s disease, the most common cause of dementia. Jiayu Zhou, an associate professor in MSU’s College of Engineering, is leading the effort that’s powered by artificial intelligence, or AI, and funded by the National Institutes of Health. In collaboration with Oregon Health & Science University and Weill Cornell Medicine, the goal is to code an easy-to-use smart phone app to help assess whether a follow-up medical diagnosis is needed.

WHO Issues First Global Report on Artificial Intelligence (AI) in Health and Six Guiding Principles for Its Design and Use
Artificial Intelligence (AI) holds great promise for improving the delivery of healthcare and medicine worldwide, but only if ethics and human rights are put at the heart of its design, deployment, and use, according to new WHO guidance published in June. The report, Ethics and governance of artificial intelligence for health, is the result of 2 years of consultations held by a panel of international experts appointed by WHO.

New VA Tool Uses Artificial Intelligence to Predict COVID-19 Patient Mortality – By Mike Richman, VA Research Communications (@DeptVetAffairs) – Tim Strebel is no stranger to the spirit of innovation. Currently a computer programmer focusing on health informatics at the Washington DC VA Medical Center, Strebel has been recognized by VA for his ingenuity. He’s a two-time winner of the VA “Shark Tank” Award, which honors innovative practices, for developing two software packages to automate the jobs of those who work in prosthetics. The software expedites the billing process for home oxygen users and the ordering of eyeglasses. Both products are used at many VA medical centers. For the eyeglass tool, he also won VA’s Gears of Government Award, which recognizes federal employees and teams whose dedication supports exceptional delivery of key outcomes for the American people.

The Basics and Resources

From the leading text book around the world, Artificial Intelligence: A Modern Approach.

Artificial Intelligence is composed of six different disciplines:

  1. Natural Language Processing to enable it to communicate successfully in English
  2. Knowledge Representation to store what it knows or hears
  3. Automated Reasoning to use the stored information to answer questions and to draw new conclusions
  4. Machine Learning to adapt to new circumstances and to detect and extrapolate patterns
  5. Computer Vision to perceive objects
  6. Robotics to manipulate objects and move about

To build a generally intelligent agent, you need machine learning in addition to the other aspects mentioned above.

Machine Learning is roughly the science of prediction. Given certain knowns (features), you wish to predict some unknowns (targets). The unknown could be structured (e.g. numeric) or unstructured (e.g. a string response).

Deep Learning is a sub field of machine learning where concepts are learned hierarchically. The simplest concepts emerge first, followed by more complicated concepts that build on the simpler ones. Usually, this leads to a simple layered hierarchy of concepts.

Natural Language Processing: AI with an ROI
Health care providers need to see a return on any analytic investment they make. Natural language processing (NLP) is one way AI can help providers convert the potential within their health data into quality improvement and cost savings. Natural language processing is an AI technology that actually makes sense for health care.
