Language models
A language model is a statistical model in NLP that is designed to learn and understand the structure of human language. More specifically, it is a probabilistic model that is trained to estimate the likelihood of words when provided with a given word scenario. For instance, a language model could be trained to predict the next word in a sentence, given the previous words.
Language models are fundamental to many NLP tasks. They are used in machine translation, speech recognition, part-of-speech tagging, and named entity recognition, among other things. More recently, they have been used to create conversational AI models such as chatbots and personal assistants and to generate human-like text.
Traditional language models were often based on explicitly statistical methods, such as n-gram models, which consider only the previous n words when predicting the next word, or hidden Markov models (HMMs).
More recently, neural networks have become popular for creating...
