WebJan 1, 2013 · Clustering analysis is widely used in many fields. Traditionally clustering is regarded as unsupervised learning for its lack of a class label or a quantitative response variable, which in contrast is present in supervised learning such as classification and regression. Here we formulate clustering as penalized regression with grouping pursuit. WebBasically they state: 1) clustering depends on a distance. 2) successful use of k-means requires a carefully chosen distance. 3) Given training data in the form of sets of items … WebDec 11, 2024 · Self-labelling via simultaneous clustering and representation learning [Oxford blogpost] (Ноябрь 2024) Как и в предыдущей работе авторы генерируют pseudo-labels, на которых потом учится модель.
