| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary A novel approach in biotechnology uses convolutional neural networks (CNNs) to analyze Raman Spectroscopy data, which measures cell densities, substrate- and product concentrations. Traditional methods employ partial least squares (PLS), but CNNs can handle non-Gaussian noise, beam misalignment, pixel malfunctions, or additional substances. However, they require extensive training data, capturing non-linear dependencies in process variables. This paper introduces a data augmentation technique that generates additional, statistically independent labeled data points from existing datasets, enabling the reuse of spectra for new contexts with different correlations. The method improves model performance and robustness by leveraging historical data. Applications include monitoring substrate, biomass, and polyhydroxyalkanoate (PHA) biopolymer concentrations during batch cultivations. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary In this study, scientists found a way to use special computer models called convolutional neural networks (CNNs) to analyze Raman Spectroscopy data. This type of analysis is important for understanding biological processes like cell growth and chemical production. The problem with traditional methods is that they can be affected by noise or mistakes in the data. CNNs are better at handling this kind of noise, but they need a lot of training data to work well. To solve this problem, the researchers came up with a clever way to generate new, labeled data points from existing datasets. This lets them use old data for new purposes and make their models more accurate and reliable. |
