Language Models are Unsupervised Multitask Learners
Language Models are Unsupervised Multitask LearnersAlec Radford*1 Jeffrey Wu*1 Rewon Child1 David Luan1 Dario Amodei**1 Ilya Sutskever**1 AbstractNatural Language processing tasks, such as ques-tion answering, machine translation, reading com-prehension, and summarization, are typicallyapproached with supervised learning on task-specific datasets. We demonstrate that languagemodels begin to learn these tasks without any ex-plicit supervision when trained on a new datasetof millions of webpages called WebText. Whenconditioned on a document plus questions, the an-swers generated by the Language model reach 55F1 on the CoQA dataset - matching or exceedingthe performance of 3 out of 4 baseline systemswithout using the 127,000+ training capacity of the Language model is essentialto the success of zero-shot task transfer and in-creasing it improves performance in a log-linearfashion across tasks.
natural language sequences in order to better predict them, regardless of their method of procurement. If a language model is able to do this it will be, in effect, performing unsupervised multitask learning. We test whether this is the case by analyzing the performance of language models in a zero-shot setting on a wide variety of tasks. 2.1.
