Introducing
#MeenaBot, a 2.6B-param open-domain chatbot with near-human quality. Remarkably, we show strong correlation between perplexity & humanlikeness!

I chatted with
#MeenaBot about the#coronavirus and her advice is to see a doctor sooner rather than later. I guess it's not a bad one & hope everyone is well! On the other hand, Meena is also excited about technology, especially VR!pic.twitter.com/pKRxfFxp38

Highly recommend watching this 8-minute video https://youtu.be/STrrlLG15OY on
#MeenaBot & the paper, with details not included the blog such as SSA vs humanlikeness correlation, sample-and-rank, removing cross-turn repetition. (Blog: https://ai.googleblog.com/2020/01/towards-conversational-agent-that-can.html …)https://twitter.com/CShorten30/status/1222655686980644864 … -
Google claims its new chatbot Meena is better than OpenAI's GPT-2

Implications from the
#MeenaBot project: 1. Perplexity might be "the" automatic metric that the field's been looking for. 2. Bots trained on large-scale social conversations & pushed hard for low perplexity will be good. 3. Safety layer is needed for respectful conversations! pic.twitter.com/WHrcstcgltPrikaži ovu nit -
We design a new human evaluation metric, Sensibleness & Specificity Average (SSA), which captures key elements of natural conversations. SSA is also shown to correlate with humanlikeness while being easier to measure. Human scores 86% SSA,
#MeenaBot 79%, other best chatbots 56%. pic.twitter.com/I7NKl2b9Tl

#MeenaBot is based on the Evolved Transformer (ET, an improved Transformer) & trained to minimize perplexity, the uncertainty of predicting the next word in a conversation. We built a novel "shallow-deep" seq2seq architecture: 1 ET block for encoder & 13 ET blocks for decoder. pic.twitter.com/Mv2d4Los3k
