Researchers have developed a meta-clustering approach using milk mid-infrared spectra to identify distinct groups of dairy cows experiencing negative energy balance during early lactation. By combining spectral filtering, dimensionality reduction techniques like PCA and autoencoders, and clustering algorithms such as k-means and spectral clustering, they identified five meta-clusters. These clusters correlated strongly with days in milk and indicated varying degrees of negative energy balance, with some groups showing rapid or early recovery. Notably, a computationally efficient PCA-based k-means method effectively replicated the findings of more complex approaches. AI
