Semantic analysis: Extracting the meaning of the text considering factors like context, synonyms, and antonyms In 2019, Google’s work in this space resulted in Bidirectional Encoder Representations from Transformers (BERT) models that were applied to search. Which led to a significant advancement in...

文本生成也就是由类别生成序列 或者 由序列到序列的预测任务。按照不同的输入划分,文本自动生成可包括文本到文本的生成(text-to-text generation)、意义到文本的生成(meaning-to-text generation)、数据到文本的生成(data-to-text generation)以及图像到文本的生成(image-to-text generation)等。具体应用如机器翻译、...
理论基础: 1954年,Harris提出分布式假说(distributional hypothesis)奠定了这种方法的理论基础:A word’s meaning is given by the words that frequently appear close-by(上下文相似的词,其语义也相似); 1957年,Firth对分布式假说做出进一步的阐述和明确:A word is characterized by the company it keeps(词的语义由...

OpenAI针对AI Alignment采用的主要技术是人在回路(human in the loop),更具体说,是强化学习+人类反馈(reinforcement learning from human feedback (RLHF)),基本思想是模型给出结果后,人类标注者给出评判,这些评判信号用于训练reward model,训练的reward model再用于强化学习更新policy。打一个不太合适的比喻,GPT-3...
Natural language processing (NLP) is a method computer programs can use to interpret human language. NLP is one type ofartificial intelligence (AI). Modern NLP models are mostly built viamachine learning, and also draw on the field of linguistics — the study of the meaning of language. ...
This is the selection of a word meaning for a word with multiple possible meanings. This uses a process of semanticanalysisto examine the word in context. For example, word sense disambiguation helps distinguish the meaning of the verb “make” in “make the grade” (to achieve) versus “ma...
