Beágyazásoknak

Beágyazásoknak is a Hungarian term that translates to "embeddings" in English. In the context of natural language processing and machine learning, embeddings refer to a type of representation for text or other data where discrete variables, such as words, are mapped to vectors of real numbers. This process transforms high-dimensional, sparse data into a lower-dimensional, dense space, capturing semantic relationships between the original items.

The core idea behind embeddings is that items with similar meanings or contexts should have similar vector representations. For instance, in a word embedding space, words like "king" and "queen" might be positioned relatively close to each other, and the vector difference between "king" and "man" might be similar to the vector difference between "queen" and "woman." This semantic understanding allows machine learning models to process and understand language more effectively.

Common methods for generating embeddings include Word2Vec, GloVe, and FastText. These techniques learn embeddings by analyzing large corpora of text, typically by predicting surrounding words given a target word or vice versa. Beyond words, embeddings can also be generated for sentences, paragraphs, documents, and even non-textual data like images or users in a recommendation system.

The applications of embeddings are widespread. They are crucial components in tasks such as machine translation, sentiment analysis, text classification, question answering, and information retrieval. By providing a meaningful numerical representation, embeddings enable machine learning algorithms to perform complex language-related tasks with greater accuracy and efficiency.
