Representation and Metric Learning Advances for Deep Neural Network Face and Speaker Biometric Systems (2022)
Abstract / truncated to 115 words
The increasing use of technological devices and biometric recognition systems in people daily lives has motivated a great deal of research interest in the development of effective and robust systems. However, there are still some challenges to be solved in these systems when Deep Neural Networks (DNNs) are employed. For this reason, this thesis proposes different approaches to address these issues. First of all, we have analyzed the effect of introducing the most widespread DNN architectures to develop systems for face and text-dependent speaker verification tasks. In this analysis, we observed that state-of-the-art DNNs established for many tasks, including face verification, did not perform efficiently for text-dependent speaker verification. Therefore, we have conducted a study ... toggle 9 keywordsbiometric systems – speaker verification – face verification – metric learning – representation learning – deep neural networks – artificial intelligence – advanced machine learning – signal processing
