The Obtain: GPT-4o’s polluted Chinese language coaching information, and astronomy’s AI problem

That is at present’s version of The Obtain, our weekday publication that gives a each day dose of what’s happening on the planet of expertise.

GPT-4o’s Chinese language token-training information is polluted by spam and porn web sites

Quickly after OpenAI launched GPT-4o final Monday, some Chinese language audio system began to note that one thing appeared off about this latest model of the chatbot: the tokens it makes use of to parse textual content have been stuffed with spam and porn phrases.

People learn in phrases, however LLMs learn in tokens, that are distinct items in a sentence which have constant and important meanings. GPT-4o is meant to be higher than its predecessors at dealing with multi-language duties, and lots of the advances have been achieved by way of a brand new tokenization device that does a greater job compressing texts in non-English languages.

However, at the very least relating to the Chinese language language, the brand new tokenizer utilized by GPT-4o has launched a disproportionate variety of meaningless phrases—and specialists say that’s probably because of inadequate information cleansing and filtering earlier than the tokenizer was skilled. If left unresolved, it might result in hallucinations, poor efficiency, and misuse. Learn the total story.

Astronomers are enlisting AI to arrange for a knowledge downpour

In deserts throughout Australia and South Africa, astronomers are planting forests of metallic detectors that may collectively scour the cosmos for radio indicators. When it boots up in 5 years or so, the Sq. Kilometer Array Observatory will search for new details about the universe’s first stars and the totally different phases of galactic evolution. 

However after synching tons of of hundreds of dishes and antennas, astronomers will shortly face a brand new problem: combing by way of some 300 petabytes of cosmological information a yr—sufficient to fill 1,000,000 laptops. So in preparation for the knowledge deluge, astronomers are turning to AI for help. Learn the total story.
