چکیده

Learning to predict signiicant events from sequences of data with categorical features is an important problem in many application areas. We focus on events for system management, and formulate the problem of prediction as a classiication problem. We perform co-occurrence analysis of events by means of Singular Value Decomposition (SVD) of the examples constructed from the data. This process is combined with Support Vector Machine (SVM) classiication, to obtain eecient and accurate predictions. We conduct an analysis of statistical properties of event data, which explains why SVM classiication is suitable for such data, and perform an empirical study using real data.

Comparison of artificial neural network and multivariate regression methods in prediction of soil cation exchange capacity (Case study: Ziaran region)

Investigation of soil properties like Cation Exchange Capacity (CEC) plays important roles in study of environmental reaserches as the spatial and temporal variability of this property have been led to development of indirect methods in estimation of this soil characteristic. Pedotransfer functions (PTFs) provide an alternative by estimating soil parameters from more readily available soil data...

نقش حروف ربط زمان دار در تعیین رابطۀ زمانی بین رویدادهای فعلی در پیکرۀ متون زبان فارسی معاصر

This paper involves in prediction of temporal relation between tensed-verb events on the basis of conjunctions in texts. For this purpose, tensed verb event data were extracted from Contemporary Persian Corpus and were examined carefully. The temporal relations between events were identified. After analyzing data on the basis of temporal relation according to Bird’s and Allen’s categorization, ...

A PRACTICAL APPROACH TO REAL-TIME DYNAMIC BACKGROUND GENERATION BASED ON A TEMPORAL MEDIAN FILTER

In many computer vision applications, segmenting and extraction of moving objects in video sequences is an essential task. Background subtraction, by which each input image is subtracted from the reference image, has often been used for this purpose. In this paper, we offer a novel background-subtraction technique for real-time dynamic background generation using color images that are taken fro...

ATR Performance Prediction Using Attributed Scattering Features

We present a method for estimating classi cation performance of a model-based synthetic aperture radar (SAR) automatic target recognition (ATR) system. Target classi cation is performed by comparing a feature vector extracted from a measured SAR image chip with a feature vector predicted from a hypothesized target class and pose. The feature vectors are matched using a Bayes likelihood metric t...

A General Architecture for Supervised Classi cation of Multivariate Time Series

Supervised classi cation has been one of the most active areas of machine learning research However the domains where it has been applied are rela tively limited In particular much of the work has focused on classi cation in static domains where the attributes of the training examples are assumed not to change over time In many domains attributes are not static in fact it is the way they vary t...
