Q) What is #KnowledgeGraph #Exploration? A) a machine-assisted process of analysis of a KG to: (1) understand its structure (2) identify whether it can satisfy the current information need and (3) locate the portion of the KG pertinent to the current need 1/4

When you put a webserver up on the internet. anywhere, hosting anything, you will see "the background radiation of the internet", and it looks like this:

I've just donated blood. You should do it too if you can.

It turns out the Turing Award is actually a silvery bowl from Tiffanys.

Nice to see a study on this! bukk.it/thisargumentis…

Deep learning training is a mathematical dumpster fire. But it turns out that if you *fix* the math, everything kinda just works…fp8 training, hyperparameter transfer, training stability, and more. [1/n]

This is true. This is sad. We should have done something about it, we should do something about it!

1/ One of most important things I've learned: Severe personality problems find *camouflage.* No one thinks “I’m a sadist” or “I'm a malignant narcissist.” They find a belief system/social group that validates their most hateful, destructive impulses & construes them as virtues.

Great (and unexpected) honor! I am also very thankful for this recognition!

Can you train a performant language models without using unlicensed text? We are thrilled to announce the Common Pile v0.1, an 8TB dataset of openly licensed and public domain text. We train 7B models for 1T and 2T tokens and match the performance similar models like LLaMA 1&2

At this point, I basically treat anything Altman says about AI like a little kid bragging about how strong their imaginary friend is. Eh, scratch that. In both cases, there is nothing backing it up but the little kid thing is generally cuter.
