The\nproposed method exploits a deep convolutional neural network (DCNN) pre-trained\nfor the face recognition task on a large dataset and then fine-tuned for the\nlarge age-gap face verification task. Finetuning is performed in a Siamese\narchitecture using a contrastive loss function. A feature injection layer is\nintroduced to boost verification accuracy, showing the ability of the DCNN to\nlearn a similarity metric leveraging external features. Experimental results on\nthe LAG dataset show that our method is able to outperform the face\nverification solutions in the state of the art considered.","url_abs":"http://arxiv.org/abs/1602.06149v1","url_pdf":"http://arxiv.org/pdf/1602.06149v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[],"tasks":[{"task_slug":"age-invariant-face-recognition","task_name":"Age-Invariant Face Recognition"},{"task_slug":"face-recognition","task_name":"Face Recognition"},{"task_slug":"face-verification","task_name":"Face Verification"}],"methods":[{"method_slug":"dcnn","method_name":"DCNN"}],"datasets_introduced":[{"slug":"large-age-gap","name":"Large Age-Gap","full_name":"Large Age-Gap"}],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1602.06149","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
