Today we’re going to talk about how neurons in a neural network learn by getting their math adjusted, called backpropagation, and how we can optimize networks by finding the best combinations of weights to minimize error. Then we’ll send...

Do you think you're good at spotting fake videos, where famous people say things they've never said in real life? See how they're made in this astonishing talk and tech demo. Computer scientist Supasorn Suwajanakorn shows how, as a grad...

What if diseases could be treated with a patient's own cells, precisely and on demand? Biotech entrepreneur Nabiha Saklayen explains how we could harness advances in biology, machine learning and lasers to create personalized stem cell...

How smart can our machines make us? Tom Gruber, co-creator of Siri, wants to make "humanistic AI" that augments and collaborates with us instead of competing with (or replacing) us. He shares his vision for a future where AI helps us...

AI is massively transforming our world, but there's one thing it cannot do: love. In a visionary talk, computer scientist Kai-Fu Lee details how the US and China are driving a deep learning revolution -- and shares a blueprint for how...

Machine learning isn't just for simple tasks like assessing credit risk and sorting mail anymore -- today, it's capable of far more complex applications, like grading essays and diagnosing diseases. With these advances comes an uneasy...

We're building an artificial intelligence-powered dystopia, one click at a time, says techno-sociologist Zeynep Tufekci. In an eye-opening talk, she details how the same algorithms companies like Facebook, Google and Amazon use to get...

Is there an equation for intelligence? Yes. It's F = T ∇ Sτ. In a fascinating and informative talk, physicist and computer scientist Alex Wissner-Gross explains what in the world that means.

What happens when we teach a computer how to learn? Technologist Jeremy Howard shares some surprising new developments in the fast-moving field of deep learning, a technique that can give computers the ability to learn Chinese, or to...

An overview of gradient descent in the context of neural networks. This is a method used widely throughout machine learning for optimizing how a computer performs on certain tasks.

Poet and policymaker Aaron Maniam describes how the language we use to explain COVID-19 shapes the way we think about it -- whether it's as a "war," a "journey" or, as he suggests, an "ecology." He encourages us to explore a range of...

The path to skill around the globe has been the same for thousands of years: train under an expert and take on small, easy tasks before progressing to riskier, harder ones. But right now, we're handling AI in a way that blocks that path...

Many of us have longed for cool sci-fi inventions like a holodeck or replicators, but there's one tool we're actually getting pretty darn close to creating: the medical tricorder.

MIT grad student Joy Buolamwini was working with facial analysis software when she noticed a problem: the software didn't detect her face -- because the people who coded the algorithm hadn't taught it to identify a broad range of skin...

Humanity is on its way to creating a "black ball": a technological breakthrough that could destroy us all, says philosopher Nick Bostrom. In this incisive, surprisingly light-hearted conversation with Head of TED Chris Anderson, Bostrom...

The use of deepfake technology to manipulate video and audio for malicious purposes -- whether it's to stoke...

Let’s try to help John Green Bot sound a bit more like the real John Green using Natural Language Processing. Today, we're going to code a program that takes a one word prompt and then completes the sentence that sounds like something...

The math of backpropagation, the algorithm by which neural networks learn.

What if your car could drop you off and then find parking by itself? According to electric vehicle entrepreneur Freeman H. Shen, this technology already exists. He shares his vision for a future where AI-powered electric vehicles will...

In an astonishing talk and tech demo, software researcher Doug Roble debuts "DigiDoug": a real-time, 3-D, digital rendering of his likeness that's accurate down to the scale of pores and wrinkles. Powered by an inertial motion capture...

Brute computing force alone can't solve the world's problems. Data mining innovator Shyam Sankar explains why solving big problems (like catching terrorists or identifying huge hidden trends) is not a question of finding the right...

Secrets, disease and beauty are all written in the human genome, the complete set of genetic instructions needed to build a human being. Now, as scientist and entrepreneur Riccardo Sabatini shows us, we have the power to read this...

The danger of artificial intelligence isn't that it's going to rebel against us, but that it's going to do exactly what we ask it to do, says AI researcher Janelle Shane. Sharing the weird, sometimes alarming antics of AI algorithms as...
