Additionally, a data fusion strategy was implemented to integrate the two spectral datasets, aiming to enhance the prediction accuracy and robustness of the quantitative models. Comparative analysis revealed that the FT-NIR model demonstrated higher accuracy in predicting moisture content, narirutin, and hesperidin levels, while the Vis/NIR-HSI model performed better in predicting color changes during the drying process of the extract. In addition to moisture content, the prediction model established by integrating the two spectral datasets through the data fusion strategy demonstrated more accurate predictive performance compared to single-spectrum models. Therefore, integrating FT-NIR and Vis/NIR-HSI spectral datasets through the data fusion strategy for online monitoring of quality changes during PVD of extract represents a rapid, non-destructive, and accurate approach to predict CQAs of materials.

Different image-level approaches are available to analyse the image properties based on the extraction of colour and texture features, and the selection of the most appropriate method is a critical point, since it could significantly impact the outcomes. The present study has three main objectives. Firstly, we propose an innovative data dimensionality reduction method to extract and codify the texture features of an RGB image into a one-dimensional signal, named texturegram (TXG). Then, TXG approach is compared with different image-level feature extraction methods, such as colourgrams (CLG), Soft Colour Texture Descriptors (SCTD) and Grey Level Co-occurrence Matrices (GLCM). These techniques were used to analyse a benchmark dataset of RGB images already considered in a previous study to build Partial Least Squares (PLS) models and relate the image features with anthocyanins content of red grape samples. We also investigated the possible advantages of combining the colour and texture information brought by the different image-level techniques using data fusion. PLS models were calculated considering different partitions of the RGB image dataset into training and test set. The performances of the different models were statistically evaluated by means of Analysis of Variance (ANOVA) and Principal Component Analysis (PCA). Overall, the results suggested an interesting, even if slight, improvement of the model performances when fusing CLG and TXG, but also highlighted the hybrid nature of TXG to simultaneously explore colour and texture properties.</div></div>","PeriodicalId":9774,"journal":{"name":"Chemometrics and Intelligent Laboratory Systems","volume":"263 ","pages":"Article 105446"},"PeriodicalIF":3.7,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines current developments in the synergistic use of AI and ML with SERS in a variety of disciplines, including environmental monitoring, food safety, pathogen detection, and disease diagnosis.

The promise of these methods is shown by the fact that some research even showed 100 % accuracy in sample identification. Food safety, environmental monitoring, and clinical diagnostics might all be revolutionized by SERS-ML techniques because of their great sensitivity, specificity, and reliability. Future research should focus on extending clinical applications, enhancing substrate capabilities and detection limitations, incorporating sophisticated machine learning techniques, and increasing the application broadness. In order to improve the robustness and practicality of these methodologies, further validation in larger cohorts and real-world contexts is also emphasized.

This algorithm combines traditional matrix factorization with artificial neural networks, leveraging the strengths of neural networks to approximate nonlinear mappings in latent variable models and utilizing all available information to minimize discrepancies between raw and generated data. Additionally, DMFDC accounts for the dynamic characteristics of the complex industrial system, employing differential operations to transform irregularly changing industrial data into a more stable sequence, thereby enabling the model to better capture data evolution patterns. This approach allows DMFDC to intelligently address the issue of missing dynamic data in the complex industrial process and to predict missing values more accurately. To evaluate its effectiveness, we conducted case studies under various missing data conditions based on a digestion dataset collected from actual alumina production sites.
