Introduction to Embeddings in Large Language Models
Evaluating embeddings is an important task to determine the quality of the embeddings. There are several methods to evaluate embeddings, and each method serves a different purpose. The most common methods are intrinsic and extrinsic evaluation.
Intrinsic evaluation is used to assess the quality of embeddings based on their performance in a specific task, such as word similarity or word analogy. For example, the word similarity task evaluates how similar two words are based on their embeddings. The word analogy task evaluates how well the embeddings capture the relationship between words, such as the relationship between 'king' and 'queen'. Intrinsic evaluation is useful to compare different embeddings for a specific task.
Extrinsic evaluation is used to evaluate the quality of embeddings based on their performance in a downstream task, such as sentiment analysis or machine translation. For example, the quality of embeddings can be evaluated by measuring their impact on the accuracy of a sentiment analysis model. Extrinsic evaluation is useful to assess the practical utility of embeddings in real-world applications.
It is important to note that the choice of evaluation method depends on the intended use of the embeddings. For example, if the embeddings will be used for sentiment analysis, extrinsic evaluation would be more appropriate. If the embeddings will be used for word similarity, intrinsic evaluation would be more appropriate.
