You will hear a university professor talking about Artificial Intelligence and making predictions about how AI might make us smarter in the future.

Write NO MORE THAN TWO WORDS for each answer.

Recognizing patterns

Deep learning

  • identifying objects in images
  • recognising speech
  • processing text

Goals of deep learning

  • represent complexity
  • generalize from previous experience

Methods for deep learning

  • Like the brain:
    • Different kinds of data handled simultaneously
    • Neurons become stronger when used, weaker when not

Successes to date

  • 1960s research into the visual cortex
  • learning algorithms invented in the nineteen eighties
  • convergence of artificial and biological intelligence

Examples of deep learning in real life

  • Google translate
  • Reading X-rays and photographs used by doctors
  • Amazon’s Alexa

AI advancing learning

When reinforcement learning is coupled with deep learning, computers become good at:

  • playing games like Go
  • making aircraft fly like birds in turbulent thermals


  • We don’t know how the brain solves problems
  • We don’t know how the brain organizes interactions between brain areas

But in the future..

  • Autonomous systems like computers may become living creatures

AI will make you smarter

Technologies modeled on how human brains work are already augmenting people’s abilities, and will only get more influential as society gets used to these increasingly capable machines. Some people fear AI might eventually make human beings obsolete. However, people are not very good at imagining the future. I would like to suggest that AI will make you smarter, but in ways that might surprise you.

Recognizing patterns

Deep learning is the part of AI that has made the most progress in solving complex problems like identifying objects in images, recognizing speech from multiple speakers and processing text the way people speak or write it. Deep learning has also proven useful for identifying patterns in the increasingly large data sets that are being generated from sensors, medical devices and scientific instruments.

The goal of this approach is to find ways a computer can represent the complexity of the world and generalize from previous experience – even if what’s happening next isn’t exactly the same as what happened before. Just as a person can identify that a specific animal she has never seen before is in fact a cat, deep learning algorithms can identify aspects of what might be called “cat-ness” and extract those attributes from new images of cats.

The methods for deep learning are based on the same principles that power the human brain. For instance, the brain handles lots of data of various kinds in many processing units at the same time. Neurons have many connections to each other, and those links strengthen or weaken depending on how much they’re used, establishing associations between sensory inputs and conceptual outputs.

The most successful deep learning network is based on 1960s research into the architecture of the visual cortex, a part of the brain that we use to see, and learning algorithms that were invented in the 1980s. Back then, computers were not yet fast enough to solve real-world problems. Now, though, they are.

In addition, learning networks have been layered on top of each other, creating webs of connections more closely resembling the hierarchy of layers found in visual cortex. This is part of a convergence taking place between artificial and biological intelligence.

Deep learning in real life

Deep learning is already adding to human capabilities. If you use Google services to search the web, or use its apps to translate from one language to another or turn speech into text, technology has made you smarter, or more effective.

These and many other systems are already at work, helping you in your daily life even if you’re not aware of them. For instance, deep learning is beginning to take over the reading of X-ray images and photographs of skin lesions for cancer detection. Your local doctor will soon be able to spot problems that are evident today only to the best experts.

Even when you do know there’s a machine involved, you might not understand the complexity of what they’re actually doing: Behind Amazon’s Alexa is a bevy of deep learning networks that recognize your request, sift through data to answer your questions and take actions on your behalf.

Advancing learning

Deep learning has been highly effective at solving pattern recognition problems, but to go beyond this requires other brain systems. When an animal is rewarded for an action, it is more likely to take similar actions in the future. Dopamine neurons in the basal ganglia of the brain report the difference between expected and received rewards, called reward prediction error, which is used to change the strengths of connections in the brain that predict future rewards.

Coupling this approach, called reinforcement learning, with deep learning can give computers the power to identify unexpected possibilities. By recognizing a pattern and then responding to it in a way that yields rewards, machines might approach behaviors along the lines of what might be called human creativity. This coupled approach is how DeepMind developed a program called AlphaGo, which in 2016 defeated grandmaster Lee Sedol and the following year beat the world Go champion, Ke Jie.

Games are not as messy as the real world, which is filled with shifting uncertainties. One researcher at the University of California, recently used reinforcement learning to teach a glider in the field how to soar like a bird in turbulent thermals.

Despite these successes, researchers do not yet fully understand how deep learning solves these problems. Of course, we don’t know how the brain solves them either.

But while the brain’s inner workings may remain elusive, it is only a matter of time before researchers develop a theory of deep learning. The difference is that when studying computers, researchers have access to every connection and pattern of activity in the network. The pace of progress is rapid, with research papers appearing daily.

There is a long way to go before computers achieve general human intelligence. The largest deep learning network today has only the power of a piece of human neural cortex the size of a rice grain. And we don’t yet know how the brain dynamically organizes interactions between larger brain areas.

Nature already has that level of integration, creating large-scale brain systems capable of operating all aspects of the human body while pondering deep questions and completing complex tasks. Ultimately, autonomous systems may become as complex, joining the myriad living creatures on our planet.
