It has made enormous development in recent years, allowing machines to not only comprehend language but also utilize it creatively and appropriately.
In this article, we will check out the different NLP language models. So, follow along, and let’s learn about these models!
1. BERT
BERT (Bidirectional Encoder Representations from Transformers) is a cutting-edge Natural Language Processing (NLP) language model. It was created in 2018 by g and is based on the Transformer architecture, a neural network built to interpret sequential input.
BERT is a pre-trained language model, which means it has been trained on massive volumes of text data to recognize natural language patterns and structure.
BERT is a bidirectional model, which means that it can grasp the context and meaning of words depending on both their previous and following phrases, making it more successful at understanding the meaning of complicated sentences.
How does It work?
Unsupervised learning is used to train BERT on massive amounts of text data. BERT gains the ability to detect missing words in a sentence or to categorize sentences during training.
With the help of this training, BERT can produce high-quality embeddings that can be applied to a variety of NLP tasks, including sentiment analysis, text categorization, question-answering, and more.
Additionally, BERT can be improved on a specific project by utilizing a smaller dataset to focus on that task specifically.

How does It work?
XLNet was created using an auto-regressive language modeling approach, which includes predicting the next word in a text sequence based on the preceding ones.
XLNet, on the other hand, adopts a bidirectional method that evaluates all potential permutations of the words in a phrase, as opposed to other language models that use a left-to-right or right-to-left approach. This enables it to catch long-term word relationships and make more accurate predictions.
XLNet combines sophisticated techniques such as relative positional encoding and a segment-level recurrence mechanism in addition to its revolutionary pre-training strategy.
