N-grams remain a fundamental statistical tool for many language modeling tasks. 3.2. Exponential Models Exponential models, such as maximum-entropy models, enhance traditional N-gram approaches by incorporating features beyond simple frequency counts. In NLP, maximum-entropy models use features such ...
NLP-Lecture 2: Language Modeling 雪豪 知乎真是个好地方 Task: 如何计算一个句子的概率/ the probability of a sequence of words, p(w1,w2,...,wn)? 这个问题等价于:在序列 w1,w2,...,wn−1 已经发生的前提下,计算下一个字是 wn 的概率, p(wn|w1,w2,...,wn−1) 一个vocabulary 的有...

NLP | 自然语言处理 - 语言模型(Language Modeling) 转:http://blog.csdn.net/lanxu_yy/article/details/29918015 为什么需要语言模型? 想象“语音识别”这样的场景,机器通过一定的算法将语音转换为文字,显然这个过程是及其容易出错的。例如,用户发音“Recognize Speech”,机器可能会正确地识别文字为“Recognize speech...
Masked language modeling (MLM) pre-training methods such as BERT corrupt the input by replacing some tokens with [MASK] and then train a model to reconstruct the original tokens. While they produce good results when transferred to downstream NLP tasks, they generally require large amounts of com...
Language models in NLP are statistically generated computational models that capture relations between words and phrases to generate new text. Essentially, they can find the probability of the next word in a given sequence of words and also the probability of a entire sequence of words. ...
