Zusammenfassung: | The invention relates to a clustering problem in the field of machine learning, in particular to a fuzzy C-means soft balance clustering algorithm driven by distribution entropy, which comprises the following steps: 1, defining the distribution entropy of a hard label matrix; 2, defining a corresponding relationship between the hard label matrix and the fuzzy membership matrix; 3, constructing a square loss term by adopting a Frobenius norm to measure the distance between the hard label matrix and the fuzzy membership matrix; 4, constructing a fuzzy C-means soft balance clustering model drivenby the distribution entropy in combination with the distribution entropy and the square loss term of the label matrix; and 5, solving the model by adopting an alternate optimization strategy.
