✨New paper✨ We find script (e.g. Cyrillic, Latin) to be a linear direction in the activation space of Whisper, enabling transliteration at test-time by adding such script directions to the activations — producing e.g. Cyrillic Japanese transcriptions.

www.nature.com/articles/350... Ted Chiang. Catching crumbs from the table. Nature 405, 517 (2000). My favorite sci-fi short, which surprisingly well-summarizes what I actually do nowadays. I bet self-supervised speech models contain undiscovered theories on phonetics and phonology.

More from inside NIH: Per a source with knowledge, for all internal research (of which there is like $10 billion worth or so), ALL purchasing shut down as of yesterday. That means gloves, reagents, anything involved with lab work, which means a lot of that work will stop.
