چکیده

The event bush is a recently developed formalism for knowledge representation optimized specifically for Earth science knowledge. It graphically represents logical and/or probabilistic dependencies between its nodes (events). Numerical data in geosciences often come in the form of time series: therefore, it is a very common situation to have tables with time-related numerical data for the variables which correspond to the events represented in an event bush. In this work, we present a way to use these numerical data to learn conditional probabilities that have to be specified in the intermediate event bush created on the basis of an event bush with temporal labels. The same idea works also if the bush also has spatial labels.

Enhancing multi-label classification by modeling dependencies among labels

In this paper, we propose a novel framework for multi-label classification, which directly models the dependencies among labels using a Bayesian network. Each node of the Bayesian network represents a label, and the links and conditional probabilities capture the probabilistic dependencies among multiple labels. We employ our Bayesian network structure learning method, which guarantees to find ...

Spatio-Temporal Event Detection Using Dynamic Conditional Random Fields

Event detection is a critical task in sensor networks for a variety of real-world applications. Many realworld events often exhibit complex spatio-temporal patterns whereby they manifest themselves via observations over time and space proximities. These spatio-temporal events cannot be handled well by many of the previous approaches. In this paper, we propose a new Spatio-Temporal Event Detecti...

Statistical Parsing with a Grammar Acquired from a Bracketed Corpus Based on Clustering Analysis

This paper proposes a new method for learning a context-sensitive conditional probability context-free grammar from an unlabeled bracketed corpus based on clustering analysis and describes a natural language parsing model which uses a probability-based scoring function of the grammar to rank parses of a sentence. By grouping brackets in a corpus into a number of similar bracket groups based on ...

Embedding conditional event algebras into temporal calculus of conditionals

In this paper we prove that all the existing conditional event algebras (abbreviated cea in this paper) embed into the three-valued extension (TLjTL) of temporal logic of discrete past time, which the authors of this paper have proposed in [TRH01] as a general model of conditional events. First of all, we discuss the descriptive incompleteness of the cea’s. In this direction, we show that some ...
