5 Beginner Friendly Steps to Learn Machine Learning and Data Science with Python

Posted by in categories: robotics/AI, science

Thinking of #Upskilling? Check this out: If you want to learn machine learning and artificial intelligence, start here:

Two years ago, I started learning machine learning online on my own. I shared my journey through YouTube and my blog. I had no idea what I was doing. I’d never coded before but decided I wanted to learn machine learning.

Even the AI Behind Deepfakes Can’t Save Us From Being Duped

Posted by in categories: information science, robotics/AI

Google and Facebook are releasing troves of deepfakes to teach algorithms how to detect them. But the human eye will be needed for a long time.

We need robots to have morals. Could Shakespeare and Austen help?

Posted by in categories: employment, ethics, law, robotics/AI

John Mullan, professor of English literature at University College London, wrote an article on The Guardian titled “We need robots to have morals. Could Shakespeare and Austen help?”.

Using great literature to teach ethics to machines is a dangerous game. The classics are a moral minefield.

When he wrote the stories in I, Robot in the 1940s, Isaac Asimov imagined a world in which robots do all humanity’s tedious or unpleasant jobs for them, but where their powers have to be restrained. They are programmed to obey three laws. A robot may not injure another human being, even through inaction; a robot must obey a human being (except to contradict the previous law); a robot must protect itself (unless this contradicts either of the previous laws).

DNA Nanomachines Are Opening Medicine to the World of Physics

Posted by in categories: biotech/medical, chemistry, nanotechnology, robotics/AI

When I imagine the inner workings of a robot, I think hard, cold mechanics running on physics: shafts, wheels, gears. Human bodies, in contrast, are more of a contained molecular soup operating on the principles of biochemistry.

Yet similar to robots, our cells are also attuned to mechanical forces—just at a much smaller scale. Tiny pushes and pulls, for example, can urge stem cells to continue dividing, or nudge them into maturity to replace broken tissues. Chemistry isn’t king when it comes to governing our bodies; physical forces are similarly powerful. The problem is how to tap into them.

In a new perspectives article in Science, Dr. Khalid Salaita and graduate student Aaron Blanchard from Emory University in Atlanta point to DNA as the solution. The team painted a futuristic picture of DNA mechanotechnology, in which we use DNA machines to control our biology. Rather than a toxic chemotherapy drip, for example, a cancer patient may one day be injected with DNA nanodevices that help their immune cells better grab onto—and snuff out—cancerous ones.

Squid-inspired robots might have environmental, propulsion applications

Posted by in categories: military, physics, robotics/AI

Inspired by the unique and efficient swimming strategy of cephalopods, scientists developed an aquatic robot that mimics their form of propulsion.

These , squidlike robots are made of , which make them hard to detect—an advantage that has potential military reconnaissance and scientific applications—while maintaining a low environmental footprint.

Physicists Xiaobo Bi and Qiang Zhu used to illustrate the physical mechanisms and fluid mechanics of a squid’s swimming method, which uses intermittent bursts through pulsed jet propulsion. By using this form of locomotion, the new can achieve impressive speeds, just like its animal inspiration. Bi and Zhu discuss their work in this week’s Physics of Fluids.

Secretive Seattle startup Picnic unveils pizza-making robot — here’s how it delivers 300 pies/hour

Posted by in categories: food, robotics/AI

After three years of quietly toiling away on a robotic food system, Seattle startup Picnic has emerged from stealth mode with a system that assembles custom pizzas with little human intervention.

Picnic — previously known as Otto Robotics and Vivid Robotics — is the latest entrant in a cohort of startups and industry giants trying to find ways to automate restaurant kitchens in the face of slim margins and labor shortages. And its journey here wasn’t easy.

“Food is hard. It’s highly variable,” said Picnic CEO Clayton Wood. “We learned a lot about food science in the process of developing the system.”

AI Can Diagnose Like Doctors. But for Continued Progress, Research Standards Must Improve

Posted by in categories: biotech/medical, health, robotics/AI

The trawl found 20,500 articles tackling the topic, but shockingly, less than 1 percent of them were scientifically robust enough to be confident in their claims, say the authors. Of those, only 25 tested their deep learning models on unseen data, and only 14 actually compared performance with health professionals on the same test sample.

Nonetheless, when the researchers pooled the data from the 14 most rigorous studies, they found the deep learning systems correctly detected disease in 87 percent of cases, compared to 86 percent for healthcare professionals. They also did well on the equally important metric of excluding patients who don’t have a particular disease, getting it right 93 percent of the time compared to 91 percent for humans.

Ultimately, then, the results of the review are broadly positive for AI, but damning of the hype that has built up around the technology and the research practices of most of those trying to apply it to medical diagnosis.
