📢New conference where AI is the primary author and reviewer! Current venues don't allow AI-written papers, so it's hard to assess the +/- of such works🤔 #Agents4Science solicits papers where AI is the main author w/ human advisors. 💡Initial reviews by

One of my favorite recent papers (and Konstantin is really great)! .When designing negotiation agents by combining #LLM with strategic information revelation, cheap talk is more natural than persuasion for guiding strategic language generation.
Bayesian persuasion is an amazing model, but what if the sender can’t commit to a persuasion scheme (think: LLM chatbot)?.Enter the cheap talk model. Konstantin Zabarnyi’s final PhD project (he’s now a @Yale postdoc!) proposes algorithmic cheap talk:.@haifengxu0 @Yang_Cai

Excited to share that our paper is named the Best Paper at this year's @TheWebConf #TheWebConf24. TL;DR: we designed an incentive-compatible mechanism for aggregating token preferences from multiple self-interested #LLM agents!. @UChicagoCS @DSI_UChicago
Sharing our new #TheWebConf2024 paper on aggregating self-interested #LLM agents. Citing meta reviewer, "the review team unanimously finds the paper novel, well-executed, and has potential to be a landmark paper sparking a new line of research linking LLMs and mechanism design".
