As the complexity and the number of medical disorders increases, both human and digital accuracies decrease.\u00a0 In fact, according to a study in the May 2020 AMIA Joint Summits on Translational Science proceedings, an increase in 10 diseases considered can cause an approximately 1% drop in top-3 accuracy.<\/p>\n<p style=\"text-align: justify;\">What if you wanted to test the accuracy of thousands of diseases?\u00a0 Do digital symptom checkers have a chance vs a human doctor?\u00a0 Preliminary results from backtests by the WellAI data scientists have shown that for significant cross-section of diseases, not only the accuracy of the WellAI\u2019s digital health assistant is higher than that for the most widely used commercial symptom checkers, it is likely higher than that for humans, in a fair comparison \u2013 i.e. when testing for thousands of diseases, not just dozens most common ones.<\/p>\n<p style=\"text-align: justify;\">What if the WellAI\u2019s digital health assistant provides more accurate diagnoses than human doctors, on average?\u00a0 Does that mean we would not need (as many) doctors?\u00a0 This is an absolutely false statement, in my opinion.\u00a0 The use of the WellAI\u2019s digital health assistant is supposed to be complementary to a doctor\u2019s knowledge.\u00a0 There is a famous joke among statisticians.\u00a0 A statistician who put his head in an oven and his feet in a freezer, noticed: \u201cOn average, I feel fine.\u201d\u00a0 There will always be situations, at least in the near future, where the human knowledge and the human experience in medicine would be hard to replicate by the machines.\u00a0 <strong>We believe in collective knowledge: Human doctors and digital health assistants are working side by side helping patients.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\">We are weeks away from launching our one-of-a-kind WellAI health and wellness platform and are excited to announce that we are offering the WellAI Founding Member discount to our first 100 paid customers.\u00a0 To get on the Waiting List, please sign up at <a href=\"https:\/\/wellai.health\/\">https:\/\/wellai.health<\/a>.<\/p>\n<p style=\"text-align: justify;\">In other WellAI news,<\/p>\n<ul style=\"text-align: justify;\">\n<li>Online event \u201cReading 25 Million Studies in Seconds\u201d will be presented by Sergei and Daniel on August 25, 2020.\u00a0 This webinar is jointly organized with the Society of Quantitative Analysts (SQA).\u00a0 Press release is available <a href=\"https:\/\/www.prnewswire.com\/news-releases\/wellai-data-scientists-to-present-latest-research-on-machine-learning-in-healthcare-and-finance-301090617.html\">here<\/a>.<\/li>\n<li>An educational show Advancements with Ted Danson to air on CNBC in September 2020.\u00a0 This episode of the show will discuss how WellAI is changing healthcare through innovations in machine learning.\u00a0 Press release is available\u00a0<a href=\"https:\/\/www.prweb.com\/releases\/advancements_with_ted_danson_to_explore_how_machine_learning_is_improving_healthcare\/prweb17205928.htm\">here<\/a>.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\">Please follow WellAI on\u00a0<a href=\"https:\/\/www.linkedin.com\/company\/wellaillc\/\">LinkedIn<\/a>,\u00a0 <a href=\"https:\/\/twitter.com\/RealWellAI\/\">Twitter<\/a>,\u00a0 <a href=\"https:\/\/www.facebook.com\/RealWellAI\/\">Facebook<\/a>,\u00a0 <a href=\"https:\/\/www.instagram.com\/realwellai\/\">Instagram<\/a>\u00a0 and <a href=\"https:\/\/t.me\/WellAI_LLC\">Telegram<\/a>\u00a0 for news and updates!<\/p>\n<p style=\"text-align: justify;\">Stay healthy!\u00a0 Be knowledgeable about your health!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; We continue sharing thoughts on my new venture, WellAI, and how it will bring revolutionary changes to healthcare.
