Which word begins with "y" and looks like an axe in this picture? (2021)
Summary: A user on Stack Exchange asked about an image of an axe next to the letter "Y" on a children's alphabet ball. The community investigated and found that the manufacturer likely mixed in a Swedish word, "Yxa," which means axe. The ball was not an official product from the original manufacturer, Hedstrom, but a knock-off version with some differences, possibly influenced by Swedish sources.

Linear Transformers Are Faster After All
Summary: Researchers Buckman and Gelada demonstrate that linear transformers can be faster than traditional transformers, contrary to previous beliefs. They present several implementation methods for linear transformers, showcasing significant speed-ups. Their chunked formulation combines the best of both attention and state algorithms, providing optimal performance. Linear transformers also offer faster inference speeds at large contexts. However, they face learning performance challenges as context size increases, resulting in instability. The authors plan to address these issues in future work.
