Quality evaluation for composting products through fuzzy latent component analysis

A fuzzy latent component analysis (FLCA) method was proposed for assessing the quality of composting products under uncertainty. In FLCA, vague and ambiguous information associated with multiple compost quality indicators were handled as fuzzy sets and converted into independent fuzzy components that had lower dimensions; the converted non-correlative component information could then be used for ranking compost quality. The proposed method was …
