Human or Not? A Gamified Approach to the Turing Test

no code implementations31 May 2023 Daniel Jannai, Amos Meron, Barak Lenz, Yoav Levine, Yoav Shoham

Over the course of a month, the game was played by over 1. 5 million users who engaged in anonymous two-minute chat sessions with either another human or an AI language model which was prompted to behave like humans.

Standing on the Shoulders of Giant Frozen Language Models

no code implementations21 Apr 2022 Yoav Levine, Itay Dalmedigos, Ori Ram, Yoel Zeldes, Daniel Jannai, Dor Muhlgay, Yoni Osin, Opher Lieber, Barak Lenz, Shai Shalev-Shwartz, Amnon Shashua, Kevin Leyton-Brown, Yoav Shoham

To demonstrate this, we introduce three novel methods for leveraging frozen models: input-dependent prompt tuning, frozen readers, and recursive LMs, each of which vastly improves on current frozen-model approaches.

Exemplar Guided Active Learning

no code implementations NeurIPS 2020 Jason Hartford, Kevin Leyton-Brown, Hadas Raviv, Dan Padnos, Shahar Lev, Barak Lenz

The challenge is that we are not informed which labels are common and which are rare, and the true label distribution may exhibit extreme skew.

PMI-Masking: Principled masking of correlated spans

1 code implementation ICLR 2021 Yoav Levine, Barak Lenz, Opher Lieber, Omri Abend, Kevin Leyton-Brown, Moshe Tennenholtz, Yoav Shoham

Specifically, we show experimentally that PMI-Masking reaches the performance of prior masking approaches in half the training time, and consistently improves performance at the end of training.
