WebThe paradigm of binary tree learning has the goal of finding a tree that iteratively splits data into meaningful, informative subgroups, guided by some criterion. Binary tree learning appears in a wide variety of problem settings across ma-chine learning. We briefly review work in two learning settings where latent tree learning plays a key ...

WebJul 1, 2024 · The searching process is guided by a learnt latent tree model which reflects the hierarchical topology of the hand. Our main contributions can be summarised as follows: (i) Learning the topology of the hand in an unsupervised, data-driven manner. ... [39] Harmeling S. and Williams C. K. I., “ Greedy learning of binary latent trees,” IEEE ... WebThis work focuses on learning the structure of multivariate latent tree graphical models. Here, the underlying graph is a directed tree (e.g., hidden Markov model, binary evolutionary tree), and only samples from a set of (multivariate) observed variables (the leaves of the tree) are available for learning the structure.
Webputational constraints; furthermore, algorithms for estimating the latent tree struc-ture and learning the model parameters are largely restricted to heuristic local search. We present a method based on kernel embeddings of distributions for ... Williams [8] proposed a greedy algorithm to learn binary trees by joining two nodes with a high WebThe BIN-A algorithm first determines the tree structure using agglomerative hierarchical clustering, and then determines the cardinality of the latent variables as for BIN-G. We …
WebA common assumption in multiple scientific applications is that the distribution of observed data can be modeled by a latent tree graphical model. An important example is phylogenetics, where the tree models the evolutionary lineages of a set of observed organisms. Given a set of independent realizations of the random variables at the leaves …
