Demystifying artificial intelligence, machine learning and deep learning

Artificial intelligence (AI), machine learning (ML), and deep learning (DL) – these buzzwords are used so interchangeably that they become fluid in interpretation. But while these emerging technologies are intertwined, they provide different levels of application.

DL is a subset of ML, and ML is a subset of AI, the umbrella term that is common to all three. In a diagram, AI is the biggest circle encapsulating ML and DL. But the progression toward smaller circles takes us to more sophisticated and brain-like systems of analyzing data and learning from it for new applications.

“Human intelligence exhibited by machines, that’s the formal definition of AI,” said Jason Mayes, senior creative engineer of Google. “Now, there are two types of AI: artificial general intelligence (AGI) and narrow AI.”

Hollywood movies such as “The Terminator” revel in the idea of AGI, where machines can successfully perform any intellectual task a human being can. While human beings might automate products and services in the future with AGI, we are now still in a phase called narrow AI.

Break down silos to make Chicago an electric transit leader

As vehicle automation and electrification gain traction, they create a new mobility ecosystem for Chicago to tap into. Yet the city’s traditional residential infrastructure and limited connectivity could hinder Chicago and other metropolises in their ability to innovate.

Waymo, Google’s autonomous car subsidiary, announced last year they would purchase over 60,000 vehicles from Fiat Chrysler and 20,000 electric vehicles from Jaguar for the self-driving car fleet.

“According to Morgan Stanley’s estimate, the potential market cap of Waymo is $175 billion if they launch an initial public offering,” said Gary A. Silberg, the Americas head of automotive innovation at the audit firm KPMG. Continue reading

5G rollout brings to life the smart hospital

Chicago-based Rush University Medical Center partnered with AT&T to deploy a fifth-generation cellular network in hospital settings, capitalizing on 5G’s fast speeds to enhance access to care and improve efficiency.

5G is expected to operate in the millimeter wave band, which has a much higher frequency than current bands of spectrum, said Randall Berry, professor of electrical engineering and computer science at Northwestern University.

“The millimeter wave communication is going to be over shorter distances,” Berry said. “Instead of having a big base station that serves a large area, you might have what are called small cells, or smaller base stations that spread out over different areas.”

By tapping into the millimeter waves, 5G could bring better capacity and ultra-high speeds to wireless networks, while offering lower latency or delays, as low as 10 milliseconds round-trip, said Rod Cruz, AT&T’s general manager of healthcare industry solutions.
