Probabilistic Graphical Models
, 2014
"... This report 1 presents probabilistic graphical models that are based on imprecise probabilities using a simplified language. In particular, the discussion is focused on credal networks and discrete domains. It describes the building blocks of credal networks, algorithms to perform inference, and dis ..."

Functions on Probabilistic Graphical Models
"... Abstract—Probabilistic graphical models are tools that are used to represent the probability distribution of a vector of random variables X = (X1,..., XN). In this paper we introduce functions f(x1,..., xN) defined over the given vector. These functions also are random variables. The main result of ..."

Abductive Inference with Probabilistic Graphical Models
"... Summary. Starting from a general characterization of logical inferences, I consider abductive reasoning, which aims at finding likely causes for observed symptoms. Such inferences are not truth preserving and thus it is necessary to assess their conclusions, to compare different explanations of the ..."

of the same findings, and finally to select the “best ” hypothesis. Since in a large number of applications probabilistic graphical models are a mathematically sound and also very convenient tool for these operations, I discuss how they can be used to make abductive inference feasible. 1
Harmonic Analysis with Probabilistic Graphical Models
, 2003
"... A technique for harmonic analysis is presented that partitions a piece of music into contiguous regions and labels each with the key, mode, and functional chord, e.g. tonic, dominant, etc. The analysis is performed with a hidden Markov model and, as such, is automatically trainable from generic MIDI ..."

MIDI files and capable of finding the globally optimal harmonic labeling. Experiments are presented highlighting our current state of the art. An extension to a more complex probabilistic graphical model is outlined in which music is modeled as a collection of voices that evolve independently given
Probabilistic Graphical Models and their Role in Databases
"... Probabilistic graphical models provide a framework for compact representation and efficient reasoning about the joint probability distribution of several interdependent variables. This is a classical topic with roots in statistical physics. In recent years, spurred by several applications in unstruc ..."

Lipschitz Parametrization of Probabilistic Graphical Models
"... We show that the log-likelihood of several probabilistic graphical models is Lipschitz continuous with respect to the ℓp-norm of the parameters. We discuss several implications of Lipschitz parametrization. We present an upper bound of the Kullback-Leibler divergence that allows understanding method ..."

A probabilistic graphical model of quantum systems
"... Abstract—Quantum systems are promising candidates of future computing and information processing devices. In a large system, information about the quantum states and processes may be incomplete and scattered. To integrate the distributed information we propose a quantum version of probabilistic grap ..."

graphical models. Variables in the model (quantum states and measurement outcomes) are linked by several types of operators (unitary, measurement, and merge/split operators). We propose algorithms for three machine learning tasks in quantum probabilistic graphical models: a belief propagation algorithm
