I. The Wars of The Roses (2020–22) “understanding wars”• GPT-3• “a field in crisis”As transformer models approached (and surpassed) “human baselines” on various NLP benchmarks, arguments were already brewing about how to interpret their capabilities. In 2020, those arguments — especially about “meaning” and “understanding” — came to a head in a paper imagining an LLM as an octopus. EMILY M.
What the Most Essential Terms in AI Really Mean

Artificial intelligence moves fast, so the first step in understanding it — and its role in science — is to know the lingo. From basic concepts like “neural networks” and “pretraining” to more contested terms like “hallucinations” and “reasoning,” here are 19 key ideas from the world of modern AI. Starting with …Artificial Intelligence / “The science and engineering of making intelligent machines,” according to John McCarthy, who coined the phrase in 1955.
How public key cryptography really works, using only simple math

For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You'd scramble the message using a special rule, known only to you and your intended audience. This rule acted like the key to a lock. If you had the key, you could unscramble the message; otherwise, you'd need to pick the lock. Some locks are so effective they can never be picked, even with infinite time and resources.

Physics dazzled Miles Cranmer from an early age. His grandfather, a physics professor at the University of Toronto, gave him books on the subject, and his parents took him to open houses at universities near their home in southern Ontario, Canada. The Perimeter Institute for Theoretical Physics was a favorite. “I remember someone talking about infinity when I was super young, and it was so cool to me,” Cranmer said.

Quantum Computers Cross Critical Error Threshold

Dec 9, 2024 | quantamagazine.org | Ben Brubaker |Susan D'Agostino |Max G. Levy |John Pavlus

Introduction How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called qubits, are exceedingly sensitive to disturbance from the outside world. Today’s prototype quantum computers are too error-prone to do anything useful. In the 1990s, researchers worked out the theoretical foundations for a way to overcome these errors, called quantum error correction.
