### 말뭉치

1. In recent years, the L-1 regularization has been extensively used to estimate a sparse precision matrix and encode an undirected graphical model.[1]
2. -This module provides an overview of graphical model representations and some of the real-world considerations when modeling a scenario as a graphical model.[2]
3. We then introduce variational methods, which exploit laws of large numbers to transform the original graphical model into a simplified graphical model in which inference is efficient.[3]
4. With the proposed method, we utilize a collective graphical model with which we can learn individual transition models from the aggregated data by analytically marginalizing the individual locations.[4]
5. Learning a spatio-temporal collective graphical model only from the aggregated data is an ill-posed problem since the number of parameters to be estimated exceeds the number of observations.[4]
6. A graphical model is a probabilistic model for which a graph denotes the conditional independence structure between random variables.[5]
7. Now, the key goal from learning a probabilistic graphical model is to learn the ‘Joint probability distribution’ represented by P(X1, X2, ..Xn) for a set of random variables.[6]
8. It is beyond the scope of this paper to describe the technical aspects of the Gaussian graphical model in detail, readers are guided to Epskamp et al.[7]
9. Illustrating the estimation of a Gaussian graphical model using the extended Bayesian information criteria (EBIC) and the glasso algorithm.[7]
10. Gaussian graphical model after applying the glasso algorithm with 4 tuning parameter values.[7]
11. The Gaussian graphical model differs from typical exploratory analysis based on partial correlational coefficients.[7]
12. From a statistical point of view, we can think of a phylogenetic tree as a graphical model .[8]
13. First, the use of restricted graphical model relies on the minimum-spanning-tree, which has been introduced in Sect.[9]
14. This type of graphical model is known as a directed graphical model, Bayesian network, or belief network.[10]
15. Fundamental to the idea of a graphical model is the notion of modularity -- a complex system is built by combining simpler parts.[11]
16. are special cases of the general graphical model formalism -- examples include mixture models, factor analysis, hidden Markov models, Kalman filters and Ising models.[11]
17. The graphical model framework provides a way to view all of these systems as instances of a common underlying formalism.[11]
18. A graphical model is a way to represent a joint multivariate probability distribution as a graph.[12]
19. In a graphical model, the nodes represent variables and the edges represent conditional dependencies among the variables.[12]
20. Nearly any probabilistic model can be represented as a graphical model: neural networks, classification models, time series models, and of course phylogenetic models![12]
21. To demonstrate how to use the Rev language to specify a graphical model, we will start with a simple non-phylogenetic model.[12]
22. In a graphical model, variables are represented by a set of nodes and their associated interactions are represented by edges.[13]
23. Before talking about how to apply a probabilistic graphical model to a machine learning problem, we need to understand the PGM framework.[14]
24. Formally, a probabilistic graphical model (or graphical model for short) consists of a graph structure.[14]
