Deep learning is probably not the way to sentience.
"Deep learning is greedy, brittle, opaque, and shallow," says Gary Marcus, a professor of cognitive psychology at NYU and briefly director of Uber's AI lab. "The systems are greedy because they demand huge sets of training data. Brittle because when a neural net is given a 'transfer test' -- confronted with scenarios that differ from the examples used in training -- it cannot contextualize the situation and frequently breaks. They are opaque because, unlike traditional programs with their formal, debuggable code, the parameters of neural networks can only be interpreted in terms of their weights within a mathematical geography. Consequently, they are black boxes, whose outputs cannot be explained, raising doubts about their reliability and biases. Finally, they are shallow because they are programmed with little innate knowledge and possess no common sense about the world or human psychology."

Single blood test screens for eight cancer types

Johns Hopkins Kimmel Cancer Center researchers developed a single blood test that screens for eight common cancer types and helps identify the location of the cancer. The test, called CancerSEEK, is a unique noninvasive, multianalyte test that simultaneously evaluates levels of eight cancer proteins and the presence of cancer gene mutations from circulating DNA in the blood. The test is aimed at screening for eight common cancer types that account for more than 60 percent of cancer deaths in the U.S. Five of the cancers covered by the test currently have no screening test. "The use of a combination of selected biomarkers for early detection has the potential to change the way we screen for cancer, and it is based on the same rationale for using combinations of drugs to treat cancers," says Nickolas Papadopoulos, Ph.D., senior author and professor of oncology and pathology.

"Brain technologies can help people learn and practise meditation," said Chris Aimone, founder of Interaxon, a Canadian startup which exhibited its Muse headband aimed at using "neurofeedback" to manage stress and improve athletic performance.

South Korea-based Looxid Labs featured a brainwave-monitoring headset which is now in the research phase but could be used for treatment of ailments like post-traumatic stress syndrome.

"We can use these brain sensors to analyze emotions and stress level," said Looxid's Honggu Lee.

Neurofeedback, which teaches self-control of brain functions, has been around for decades, but the arrival of low-cost sensors has made it easier to produce affordable consumer devices.

"Woebot: AI for mental health." "While a software chatbot will never replace a human therapist, Woebot makes it possible to inexpensively deliver counseling to millions. Woebot delivers a mood management program based on Cognitive Behavior Therapy (CBT). A Stanford University randomized controlled trial showed that Woebot reduced symptoms of depression and anxiety in 2 weeks."
