Word2vec was developed by Tomáš Mikolov and colleagues at Google and published in 2013. Word2vec represents a word as a high-dimension vector of numbers which capture relationships between words. In particular, words which appear in similar contexts are mapped to vectors which are nearby as measured by cosine similarity .
In natural language processing, a word embedding is a representation of a word. The embedding is used in text analysis.Typically, the representation is a real-valued vector that encodes the meaning of the word in such a way that the words that are closer in the vector space are expected to be similar in meaning.

Mikolov obtained his PhD in Computer Science from Brno University of Technology for his work on recurrent neural network-based language models. [1] [2] He is the lead author of the 2013 paper that introduced the Word2vec technique in natural language processing [3] and is an author on the FastText architecture.
On October 25, 2019, Google announced that they had started applying BERT models for English language search queries within the US. [27] On December 9, 2019, it was reported that BERT had been adopted by Google Search for over 70 languages. [28] [29] In October 2020, almost every single English-based query was processed by a BERT model. [30]

A large language model (LLM) is a type of machine learning model designed for natural language processing tasks such as language generation.LLMs are language models with many parameters, and are trained with self-supervised learning on a vast amount of text.
Alphabet, Apple, Nvidia, Microsoft, and Tesla are all down year to date, with an average drop of 3% based on Yahoo Finance's calculations. Tesla is the worst performer, off by 17% this year .
Deeplearning4j includes implementations of term frequency–inverse document frequency , deep learning, and Mikolov's word2vec algorithm, [20] doc2vec, and GloVe, reimplemented and optimized in Java. It relies on t-distributed stochastic neighbor embedding (t-SNE) for word-cloud visualizations.
