Limits To Computing: A Computer Scientist Explains Why Even In The Age Of AI, Some Problems Are Just Too Difficult

Computers are growing more powerful and more capable, but everything has limits. Jie Wang, UMass Lowell Empowered by artificial intelligence technologies, computers today can engage in convincing conversations with people, compose songs, paint paintings, play chess and go, and diagnose diseases, to name just a few examples of their technological prowess. These successes could be taken to indicate that computation has no limits. To see if that’s the case, it’s important to understand what makes a computer powerful. There are two aspects to a computer’s power: the number of operations its hardware can execute per second and the efficiency of…

Flexible AI Computer Chips Promise Wearable Health Monitors That Protect Privacy

The Research Brief is a short take about interesting academic work. The big idea My colleagues and I have developed a flexible, stretchable electronic device that runs machine-learning algorithms to continuously collect and analyze health data directly on the body. The skinlike sticker, developed in my lab at the University of Chicago’s Pritzker School of Molecular Engineering, includes a soft, stretchable computing chip that mimics the human brain. To create this type of device, we turned to electrically conductive polymers that have been used to build semiconductors and transistors. These polymers are made to be stretchable, like a rubber band.…

Machine Learning Helps Scientists Peer (a second) Into The Future

The past may be a fixed and immutable point, but with the help of machine learning, the future can at times be more easily divined. Using a new type of machine learning method called next generation reservoir computing, researchers at The Ohio State University have recently found a new way to predict the behavior of spatiotemporal chaotic systems — such as changes in Earth’s weather — that are particularly complex for scientists to forecast. The study, published today in the journal Chaos: An Interdisciplinary Journal of Nonlinear Science, utilizes a new and highly efficient algorithm that, when combined with next generation…

How AI Can Worsen Health Care Disparities?

Data sources that “teach” artificial intelligence could amplify and worsen disparities in health care, says law professor Nicholson Price. Those data sources are not representative and/or are based on data from current unequal care, says Price, a member of the University of Michigan’s Institute for Healthcare Policy & Innovation. In a recent article in Science, Price and colleagues Ana Bracic of Michigan State University and Shawneequa Callier of George Washington University say these disparities are happening despite efforts in medicine by physicians and health systems trying strategies focused on diverse workforce recruitment or implicit bias training. Here, Price answers questions about bias and AI in healthcare: Q What is an example of anti-minority culture? A…

AI Predictions For 2022 And Beyond

We have all been down the same train of thought regarding artificial intelligence, thanks to sci-fi films peppered throughout the history of Hollywood: Artificial intelligence is too dangerous. However, as time has proven over and over again, humankind is unable to duplicate the same kind of AI that we see in the movies..yet. Any attempt at creating artificial intelligence is garnered towards machine learning and semantic similarity. We’re still a long way from sentient A.I, but here’s what’s going on in the industry and what we can expect moving forward. Forbes and Their Predictions for the Future The prestigious business magazine…

Accelerating The Discovery Of New Materials For 3D Printing

The growing popularity of 3D printing for manufacturing all sorts of items, from customized medical devices to affordable homes, has created more demand for new 3D printing materials designed for very specific uses. To cut down on the time it takes to discover these new materials, researchers at MIT have developed a data-driven process that uses machine learning to optimize new 3D printing materials with multiple characteristics, like toughness and compression strength. By streamlining materials development, the system lowers costs and lessens the environmental impact by reducing the amount of chemical waste. The machine learning algorithm could also spur innovation…

Artificial Intelligence Is Now Part Of Our Everyday Lives – And Its Growing Power Is A Double-Edged Sword

A major new report on the state of artificial intelligence (AI) has just been released. Think of it as the AI equivalent of an Intergovernmental Panel on Climate Change report, in that it identifies where AI is at today, and the promise and perils in view. From language generation and molecular medicine to disinformation and algorithmic bias, Artificial Intelligence has begun to permeate every aspect of our lives. The report argues that we are at an inflection point where researchers and governments must think and act carefully to contain the risks AI presents and make the most of its benefits.…

Recommender Engines: AI On Steroids For E-commerce

When I open any website offering services or goods, I always check how well a recommender system works. It’s my personal marketing thing, tic, and oddity. Whatever you call it. Big business also adores recommender engines as much as I do, so I am in good company. “Recommender engines or recommenders, as they are sometimes called, are the most useful applications of Machine Learning Algorithms.” – Harvard Business Review. No matter whether I am choosing Netflix movies or ordering delivery from a local grocery, I want personal recommendations: Recommender engines help me to choose among millions of tracks on Spotify: And they help me to…

How Humans And Machines Can Enhance Each Other’s Strengths With Collaborative Intelligence

“Artificial intelligence is transforming all sectors of the economy, but there’s no reason to fear that robots will replace all human employees. In fact, companies that automate their operations mainly to cut their workforces will see only short-term productivity gains, say the authors. Their research, involving 1,500 firms in a range of industries, shows that the biggest performance improvements come when humans and smart machines work together, enhancing each other’s strengths. People need to train AI agents, explain their outputs, and make sure they are used responsibly. AI agents, in turn, can assist people with information gathering, data crunching, routine…

7 Sneaky Ways Hackers Are Using Machine Learning to Steal Your Data

Machine learning is famous for its ability to analyze large data sets and identify patterns. It is basically a subset of artificial intelligence. Machine learning uses algorithms that leverages previous data-sets and statistical analysis to make assumptions and pass on judgments about behavior. The best part, software or computers powered by machine learning algorithms can perform functions that they have not been programmed to perform. Despite the machine learning challenges, this makes it an ideal choice for identifying cybersecurity threats and mitigating the risk. Microsoft did just that with its Windows Defender in 2018. Equipped with multiple layers of machine learning,…
