As a first stage of both pipelines, we compare the performance of three convolutional autoencoders. We use the PCA method together with t-SNE as the first pipeline and the reconstruction errors based method as the second. Both methods have potential for the anomaly detection, but the reconstruction error metrics prove to be more robust for this task. We show that the convolutional autoencoder architecture doesn't have a significant effect for this task and we prove the potential of our approach on the real world dataset.","url_abs":"https://arxiv.org/abs/2203.06747v1","url_pdf":"https://arxiv.org/pdf/2203.06747v1.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":[{"paper_slug":"feature-space-reduction-as-data-preprocessing","repo_url":"https://github.com/boortel/ae-reconstruction-and-feature-based-ad","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"tf","reach":null}],"tasks":[{"task_slug":"anomaly-detection","task_name":"Anomaly Detection"}],"methods":[{"method_slug":"pca","method_name":"PCA"},{"method_slug":"svm","method_name":"SVM"}],"datasets_introduced":[{"slug":"industry-biscuit-cookie-dataset","name":"Industry Biscuit (Cookie) dataset","full_name":"Industrial style dataset for the anomaly detection"}],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
