We trained a decoder to read the internal activations of an LLM and answer questions about what the model will think about or do next.
We find that this decoder can understand LLM behaviors, even when the model itself is confused! (for instance, if the model has been jailbroken)

(1/🎉) Social structures are built from plausibly deniable interactions, but how do we engineer them into digital systems? Here's TADA: Time-Assured Deniable Authentication! aka my earworm for the past month :) https://t.co/UpSkOQO6pK

Super grateful to have gotten to work with these beautiful souls, and to connect with some visitors and locals in Chiang Mai :)

Hope to continue conversations around understanding local landscapes to create conscious, positive-sum interactions with communities we participate in~

What happens when you ask strangers in Thailand about their lives?

Last month, @aaleksandar, @JanabelXia, and I interviewed some locals in Chiang Mai to better understand their lives, communities, and perspectives

[Janabel Xia @JanabelXia]

for unknown reasons i now find myself listening to the soundtrack of everything everywhere all at once and it’s ruining me

[Janabel Xia @JanabelXia]

i felt like cambridge was beautiful today -- the weather, the live music in central, the sunlight filtered through the trees, the people i met with, everything

[Janabel Xia @JanabelXia]

today i biked to allston w/ a friend and i) realized how terrible the bike lanes are outside of cambridge, and ii) was vv glad that i decided to start wearing a helmet today

[Janabel Xia @JanabelXia]

I used to think I could do math research with a 9-5 schedule

[Janabel Xia @JanabelXia]

@fluorane ooo examples?

[Janabel Xia @JanabelXia]

the improv book I read gave examples of how the exercises can play out both absurdly and well…in practice so far it has only been absurd :p

i cut my hair recently (the shortest it has ever been except at birth I guess) and idk if I can ever go back - less hair product, lighter head, less hair in my face, cooler for the summer, and I love the look :))

[Janabel Xia @JanabelXia]

@_dorwho theatre improv!
