High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

open access: yesJournal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Raman Spectroscopy and Generative Variational Autoencoders for Metallurgical Coke Quality Prediction

open access: yesJournal of Raman Spectroscopy, EarlyView.
An integrated soft sensor framework combining standardized Raman spectroscopy, synergy‐vector feature selection, variational autoencoder‐based data augmentation, and regression models (kNN, PLS, and SVR) predicts metallurgical coke quality (CSR and DI).

The Carbonate Raman Processing and Plotting Tool: A Software Application for 2‐Dimensional Raman Image Peak‐Fitting and Visualization

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present the Carbonate Raman Processing and Plotting tool (CaRPP), designed to perform peak‐fitting and visualization on two‐dimensional Raman maps of calcium carbonate specimens. Users begin by providing a raw Raman data file and then interactively use the application to perform peak‐fitting, masking, and 2‐D image generation.

Rapid Quantification of Fatty Acids in Fish Eggs Through Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Omega‐3 fatty acids (FAs) are important indicators for egg quality. This study uses Raman spectroscopy coupled with chemometrics to develop a rapid and in situ method for predicting FA composition in fish eggs. These findings offer a practical and cost‐effective method for assessing egg FA profiles in aquaculture hatcheries.
