Existing 1D analysis methods often rely on traditional chemometric approaches and rarely exploit the full potential of online data augmentation, novel architectures, and explainability methods common in image analysis. To address these gaps, a novel approach is proposed that transforms 1D signals into 2D spider plot visualizations, enabling utilization of pretrained deep learning models originally developed for image datasets. The approach also allows transformation of model interpretation maps back to the original variable space, making them more intuitive. The general applicability of this method is demonstrated across multiple data types: Raman spectra, mid\u2010infrared spectra, electrocardiograms, and mass spectrometry data (MALDI\u2010IMS). The method achieves competitive performance, reaching a balanced accuracy of 99% in Raman\u2010based oil identification tasks, surpassing principal component analysis combined with linear discriminant analysis (94%). Performance across datasets reflects variability due to data complexity, highlighting the method's versatility and potential across diverse signal types. This visualization\u2010based strategy presents an innovative solution to overcome dataset\u2010size and model\u2010related limitations while enhancing interpretability in complex 1D data analysis.<\/jats:p>","DOI":"10.1002\/aisy.202500069","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T00:50:10Z","timestamp":1750899010000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Adapting Image\u2010Based Models for 1D Data via Spider Plot Transformation and Transfer Learning"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-7684-8289","authenticated-orcid":false,"given":"Azadeh","family":"Mokari","sequence":"first","affiliation":[{"name":"Leibniz Institute of Photonic Technology Member of Research Alliance \u201cLeibniz Health Technologies\u201d  07745 Jena Germany"},{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  07743 Jena Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4655-8080","authenticated-orcid":false,"given":"Oleg","family":"Ryabchykov","sequence":"additional","affiliation":[{"name":"Leibniz Institute of Photonic Technology Member of Research Alliance \u201cLeibniz Health Technologies\u201d  07745 Jena Germany"},{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  07743 Jena Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2778-6624","authenticated-orcid":false,"given":"Thomas","family":"Bocklitz","sequence":"additional","affiliation":[{"name":"Leibniz Institute of Photonic Technology Member of Research Alliance \u201cLeibniz Health Technologies\u201d  07745 Jena Germany"},{"name":"Institute of Physical Chemistry Friedrich Schiller University Jena  07743 Jena Germany"}]}],"member":"311","published-online":{"date-parts":[[2025,6,25]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compbiomed.2024.107976"},{"key":"e_1_2_9_3_1","first-page":"1","volume":"28","author":"Basoum M.","year":"2024","journal-title":"Sci.
