We introduce a new domain expert mixture (DEMix) layer that enables conditioning a language model (LM) on the domain of the input text. A DEMix layer is a collection of expert feedforward networks, each specialized to a domain, that makes the LM modular: experts can be mixed, added or removed after initial training. Extensive experiments with autoregressive transformer LMs (up to 1.3B parameters) show that DEMix layers reduce test-time perplexity, increase training efficiency, and enable rapid adaptation with little overhead. We show that mixing experts during inference, using a parameter-free weighted ensemble, allows the model to better generalize to heterogeneous or unseen domains. We also show that experts can be added to iteratively incorporate new domains without forgetting older ones, and that experts can be removed to restrict access to unwanted domains, without additional training. Overall, these results demonstrate benefits of explicitly conditioning on textual domains during language modeling.

On March 11, 2021, the auction house Christie's sold a work by an American graphic designer, Michael Winkelmann, a.k.a. Beeple, for a colossal $69 million, making it the third most expensive work ever sold by a living artist. The work, Everydays: The First 5000 Days, is a nonfungible token, or NFT. It's a computer file that cannot be exchanged, copied, or destroyed, which gives the purchaser proof of authenticity. It lives online in a virtual space--an immaterial space--in a blockchain, a secure digital public ledger.

In a video interview with Access Hollywood, comedian Kevin Hart endorses Donald Trump for president in 2024. The clip goes viral, and his fans are up in arms. Meanwhile, WKCU in Phoenix leads with a story that a second coronavirus has hit the mainland … and it's time to panic.

But the debates between Facebook and the White House throughout the spring and into summer also gave rise to a broader and still unresolved disagreement over what constitutes misinformation, according to the person familiar with Facebook's thinking. Facebook strongly believes people should have the right to broadly express themselves without censorship on social platforms, and had reviewed research that shows that friends and family can often be more effective at countering misinformation than official sources that people distrust. The Facebook executives thought the Biden camp was going too far, by identifying specific pieces of content as problematic and asking it to potentially suppress valuable conversations where people express fears and skepticism.

With machine learning, researchers can use the abundance of historical climate data and observations to improve predictions of Earth's future climate.

Artificial Intelligence is taking over the music industry. These AI songs are a blend of human and AI technologies like machine learning.

STEMpedia is going to launch a revolutionary AI learning kit that will transform the conventional learning system as we know it. Known as Quarky, the kit allows kids aged seven to 14 years old to enjoy the thrill of emerging technologies by indulging in exciting hands-on learning. Quarky opens a world of possibilities for kids as they learn, innovate and grow. Being much more than just an educational kit, it allows them to explore real-world application-based concepts of AI, robotics, and programming. Kids can learn and unleash their curiosity by building DIY robots based on machine learning, speech recognition, face recognition, and much more, thereby making their own Alexa, self-driving cars, face-unlocks, and whatnot!
