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…

Tweaking AI Software To Function Like A Human Brain Improves Computer’s Learning Ability

Computer-based artificial intelligence can function more like human intelligence when programmed to use a much faster technique for learning new objects, say two neuroscientists who designed such a model that was designed to mirror human visual learning. In the journal Frontiers in Computational Neuroscience, Maximilian Riesenhuber, PhD, professor of neuroscience, at Georgetown University Medical Center, and Joshua Rule, PhD, a postdoctoral scholar at UC Berkeley, explain how the new approach vastly improves the ability of AI software to quickly learn new visual concepts. “Our model provides a biologically plausible way for artificial neural networks to learn new visual concepts from a…

To Make Sense Of AI Decisions, ‘Peek Under The Hood’

Now that humans have programmed computers to learn, we want to know exactly what they’ve learned and how they make decisions after their learning process is complete. The answers to such questions could shed light on our own decision-making processes. Kate Saenko, an associate professor of computer science at Boston University, asked humans to look at dozens of pictures depicting steps that the computer may have taken on its road to a decision, and identify its most likely path. The humans gave answers that made sense, but there was a problem: they made sense to humans, and humans, Saenko knew,…

How Computers Help Biologists Crack Life’s Secrets

Once the three-billion-letter-long human genome was sequenced, we rushed into a new “omics” era of biological research. Scientists are now racing to sequence the genomes (all the genes) or proteomes (all the proteins) of various organisms – and in the process are compiling massive amounts of data. For instance, a scientist can use “omics” tools such as DNA sequencing to tease out which human genes are affected in a viral flu infection. But because the human genome has at least 25,000 genes in total, the number of genes altered even under such a simple scenario could potentially be in the…

Artificial Intelligence: Computer Says YES (But Is It Right?)

Computers that learn for themselves are with us now. As they become more common in ‘high-stakes’ applications like robotic surgery, terrorism detection and driverless cars, researchers ask what can be done to make sure we can  trust them. There would always be a first death in a driverless car and it happened in May 2016. Joshua Brown had engaged the autopilot system in his Tesla when a tractor-trailer drove across the road in front of him. It seems that neither he nor the sensors in the autopilot noticed the white-sided truck against a brightly lit sky, with tragic results. As…

Neven’s Law: Why It Might Be Too Soon For A Moore’s Law For Quantum Computers

A new disruptive technology is on the horizon and it promises to take computing power to unprecedented and unimaginable heights. And to predict the speed of progress of this new “quantum computing” technology, the director of Google’s Quantum AI Labs, Hartmut Neven, has proposed a new rule similar to the Moore’s Law that has measured the progress of computers for more than 50 years. But can we trust “Neven’s Law” as a true representation of what is happening in quantum computing and, most importantly, what is to come in the future? Or is it simply too early on in the…

Light, A Possible Solution For A Sustainable Artificial Intelligence

We are currently witnessing a rapidly growing adoption of artificial intelligence (AI) in our everyday lives, which has the potential to translate into a variety of societal changes, including improvements to economy, better living conditions, easier access to education, well-being, and entertainment. Such a much anticipated future, however, is tainted with issues related to privacy, explainability, accountability, to name a few, that constitute a threat to the smooth adoption of AI, and which are at the center of various debates in the media. A perhaps more worrying aspect is related to the fact that current AI technologies are completely unsustainable,…
