WebDec 1, 2024 · A fuzzy clustering model for data with mixed features is proposed. The clustering model allows different types of variables, or attributes, to be taken into account. This result is achieved by combining the dissimilarity measures for each attribute by means of a weighting scheme, so as to obtain a distance measure for multiple attributes. The … WebThe previous paragraph talks about if K-means or Ward's or such clustering is legal or not with Gower distance mathematically (geometrically).
