Is cosine similarity a doog measure in speaker recognition? 


Best insight from top research papers

Cosine similarity is a commonly used measure in speaker recognition systems. While it offers computational efficiency, recent research suggests that alternative distance metrics can outperform cosine similarity in certain scenarios. For instance, Mahalanobis distance scoring with metric learning algorithms has shown improved performance over cosine similarity in speaker verification tasks. Additionally, techniques like cosine similarity learning frameworks have been developed to enhance equal-error-rate (EER) performance by minimizing overlap regions and controlling variance. Moreover, studies have explored optimizing cosine similarity through orthogonal and diagonal matrices to reduce equal error rates significantly. Therefore, while cosine similarity remains a widely used measure, advancements in distance metrics like Mahalanobis distance and cosine similarity learning frameworks have demonstrated superior performance in speaker recognition tasks.

What are the advantages and disadvantages of using cosine as a metric to measure similarity?5 answersCosine similarity has several advantages as a metric to measure similarity. It is widely used in various fields such as large-scale image retrieval and language modeling. It offers low storage cost, high computational efficiency, and good retrieval performance.
