  2. Probabilistic classification - Wikipedia

    en.wikipedia.org/wiki/Probabilistic_classification

    In machine learning, a probabilistic classifier is a classifier that is able to predict, given an observation of an input, a probability distribution over a set of classes, rather than only outputting the most likely class that the observation should belong to.

  3. List of datasets for machine-learning research - Wikipedia

    en.wikipedia.org/wiki/List_of_datasets_for...

    High-quality labeled training datasets for supervised and semi-supervised machine learning algorithms are usually difficult and expensive to produce because of the large amount of time needed to label the data. Although they do not need to be labeled, high-quality datasets for unsupervised learning can also be difficult and costly to produce ...

  4. Model-based clustering - Wikipedia

    en.wikipedia.org/wiki/Model-based_clustering

    Model-based clustering was first invented in 1950 by Paul Lazarsfeld for clustering multivariate discrete data, in the form of the latent class model. [ 41 ] In 1959, Lazarsfeld gave a lecture on latent structure analysis at the University of California-Berkeley, where John H. Wolfe was an M.A. student.

  5. Machine learning - Wikipedia

    en.wikipedia.org/wiki/Machine_learning

    Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalize to unseen data, and thus perform tasks without explicit instructions. [1]

  6. k-medoids - Wikipedia

    en.wikipedia.org/wiki/K-medoids

    In contrast to the k-means algorithm, k-medoids chooses actual data points as centers (medoids or exemplars), and thereby allows for greater interpretability of the cluster centers than in k-means, where the center of a cluster is not necessarily one of the input data points (it is the average between the points in the cluster).

  7. Cluster analysis - Wikipedia

    en.wikipedia.org/wiki/Cluster_analysis

    Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some specific sense defined by the analyst) to each other than to those in other groups (clusters).

  8. Statistical classification - Wikipedia

    en.wikipedia.org/wiki/Statistical_classification

    Naive Bayes classifier – Probabilistic classification algorithm; Perceptron – Algorithm for supervised learning of binary classifiers; Quadratic classifier – used in machine learning to separate measurements of two or more classes of objects

  9. Estimation of distribution algorithm - Wikipedia

    en.wikipedia.org/wiki/Estimation_of_distribution...

    The linkage-tree learning procedure is a hierarchical clustering algorithm, which work as follows. At each step the two closest clusters i {\displaystyle i} and j {\displaystyle j} are merged, this procedure repeats until only one cluster remains, each subtree is stored as a subset τ ∈ T LT {\displaystyle \tau \in T_{\text{LT}}} .
