100 Best Word Embedding Videos


Notes:

Word embedding is a technique in natural language processing that represents words or phrases in a high-dimensional, continuous vector space. It maps each word or phrase to a fixed-length vector of real numbers, where the vector components capture the semantic meaning of the word or phrase. For example, words and phrases that are semantically similar, such as “cat” and “kitten” or “king” and “queen,” would have similar or close vector representations in the word embedding space.

Word embedding is used for a variety of natural language processing tasks, such as language modeling, text classification, and machine translation. It allows machine learning algorithms to work with words and phrases in a continuous, numerical representation, rather than as discrete, symbolic tokens. This can improve the performance and accuracy of natural language processing systems, by providing a more intuitive and expressive representation of the meaning of words and phrases.

Word embedding is typically learned from large amounts of text data using unsupervised learning algorithms, such as word2vec and GloVe. These algorithms analyze the co-occurrence of words in the training data to learn the relationships between words and their meanings, and to generate the vector representations of words in the embedding space. Once the word embedding has been learned, it can be used as a lookup table to map words and phrases to their corresponding vector representations, and can also be fine-tuned or adjusted for specific tasks or domains.

  • Distributional semantic model is a type of computational model that is used to represent the meanings of words and phrases in a language. It is based on the idea that the meaning of a word can be inferred from the context in which it is used, and it typically involves representing words as vectors in a high-dimensional space.
  • Distributed representation refers to the idea that the meaning of a word or concept can be represented by a distributed pattern of activation across a large number of neurons or dimensions in a neural network or other computational model. This is in contrast to a localist representation, where each word or concept is represented by a single neuron or dimension.
  • Neural word embedding is a technique for representing words as vectors in a high-dimensional space, typically using a neural network. The vectors are learned in a way that reflects the relationships between words in the language, and they can be used as input to other machine learning models to perform tasks such as language translation or text classification.
  • Semantic vector space is a high-dimensional space in which words or phrases are represented as vectors, with the vectors reflecting the meanings of the words or phrases. Semantic vector spaces are often used in natural language processing (NLP) to represent the meanings of words in a way that can be understood by computational models.
  • Vector space model is a mathematical model that represents the relationships between a set of vectors in a high-dimensional space. Vector space models are often used in natural language processing (NLP) to represent the meanings of words and phrases, and to compute similarities between them.
  • Word vectors are numerical representations of words that are used to encode the meanings of words in a high-dimensional space. Word vectors are often learned using techniques such as neural word embedding, and they can be used as input to machine learning models to perform tasks such as language translation or text classification.
