This paper describes wav2vec-U, short for wav2vec Unsupervised, a method to train speech recognition models without any labeled data.

Our method jointly optimizes a latent-space model and policy to be self-consistent, such that the policy avoids states where the model is inaccurate.

"I don't feel particularly unhappy about my work being used to train AI," says Japanese novelist Rie Qudan. "Even if it is copied, I feel confident there's a part of me that will remain, which nobody can copy." The 34-year old author is talking to me via Zoom from her home near Tokyo, ahead of the publication of the English-language translation of her fourth novel, Sympathy Tower Tokyo. The book attracted controversy in Japan when it won a prestigious prize, despite being partly written by ChatGPT. At the heart of Sympathy Tower Tokyo is a Japanese architect, Sara Machina, who has been commissioned to build a new tower to house convicted criminals. It will be a representation of what one character – not without irony – calls "the extraordinary broadmindedness of the Japanese people", in that the tower will house offenders in compassionate comfort.

We run our experiments using PyTorch's distributed training on an Azure ML Nvidia DGX-2 In this section we present all the hyper-parameters used for training our models. We fix the gradient norm to be 1 and set the batch size as 1024 in all experiments based on [ 75, 34 ]. Structured pruning can be done by pruning attention heads, pruning encoder units, or pruning the embedding layer. KD is quite different from ours.

As a concrete example, consider a language model that is deployed for sentence completion task in text editors.

Ask an adult what they think about kids and AI, and expect to hear a strong opinion. Parents, politicians, experts--everyone has a take on whether young people should use AI, how to moderate their exposure, and how it's changing the ways they think and communicate. Many of these opinions revolve around education. Adults fret that kids will turn ChatGPT into a research bot, paper writer, or math problem solver. Teachers, specifically, struggle to know how to deal with policing student use, and how to include it in their own pedagogy.
