TL;DR: Ising models, suitable for dichotomic clustering, are introduced, with couplings that are both ferro- and anti-ferromagnetic depending on the whole data-set and not only on pairs of samples, with a link between kernel supervised and unsupervised learning.

Semi-supervised learning by search of optimal target vector
TL;DR: In this paper, a semi-supervised learning estimator which tends to the first kernel principal component as the number of labeled points vanishes is introduced, based on the notion of optimal target vector, which is defined as follows.

A Modified Mountain Clustering Algorithm based on Hill Valley Function
Junnian Wang,Deshun Liu,Chao Liu +2 more
TL;DR: The testing of four databases indicate that the proposed clustering algorithm can categorise the data numbers in each cluster and find all the cluster centres exactly, and no need priori parameters and stopping criterion correlating to the database.

Optimization by Simulated Annealing
TL;DR: There is a deep and useful connection between statistical mechanics and multivariate or combinatorial optimization (finding the minimum of a given function depending on many parameters), and a detailed analogy with annealing in solids provides a framework for optimization of very large and complex systems.

TL;DR: A generic approach to cancer classification based on gene expression monitoring by DNA microarrays is described and applied to human acute leukemias as a test case and suggests a general strategy for discovering and predicting cancer classes for other types of cancer, independent of previous biological knowledge.
