The neural network is trained on massive amounts of bilingual data to learn how to translate effectively. During translation, the input text is first tokenized into individual words or phrases, and each token is assigned a unique identifier. The tokens are then fed into the neural network, which processes them in a series of layers to generate a probability distribution over the possible translations. The output from the network is a sequence of tokens in the target language, which are then converted back into words or phrases for the final translated text. The neural network is trained to optimize for translation accuracy, considering both the meaning and context of the input text.

Natural language processors are extremely efficient at analyzing large datasets to understand human language as it is spoken and written. However, typical NLP models lack the ability to differentiate between useful and useless information when analyzing large text documents. Therefore, startups are applying machine learning algorithms to develop NLP models that summarize lengthy texts into a cohesive and fluent summary that contains all key points.

Stop words are words that relate to the most common words in a language and do not contribute much sense to a statement; thus, they can be removed without changing the sentence. Furthermore, stemming and lemmatization are the last NLP techniques used on the dataset. The two approaches are used to reduce a derived or inflected word to its root, base, or stem form. The distinction between stemming and lemmatization is that lemmatization assures that the root word (also known as a lemma) is part of the language.
