Finding similar situations in sequences of events via random projections

چکیده
Sequences of events occur in several applications, such as mobile services (the requests made by each user), telecommunication network alarm handling, user interface studies, etc. Such a sequence can be denoted (〈ei, ti〉), where i = 1, . . . , n, and for each i, ei ∈ E is an event type and ti is the occurrence time. As an example, consider the following excerpt from a sequence of 46662 events (alarms) from a telecommunications network. Here the first field is the alarm type, and the second is the occurrence time.

Relation Between RNA Sequences, Structures, and Shapes via Variation Networks
Background: RNA plays key role in many aspects of biological processes and its tertiary structure is critical for its biological function. RNA secondary structure represents various significant portions of RNA tertiary structure. Since the biological function of RNA is concluded indirectly from its primary structure, it would be important to analyze the relations between the RNA sequences and t...
متن کاملAuthor gender identification from text using Bayesian Random Forest
Nowadays high usage of users from virtual environments and their connection via social networks like Facebook, Instagram, and Twitter shows the necessity of finding out shared subjects in this environment more than before. There are several applications that benefit from reliable methods for inferring age and gender of users in social media. Such applications exist across a wide area of fields,...
متن کاملOptimal Stopping Policy for Multivariate Sequences a Generalized Best Choice Problem
In the classical versions of “Best Choice Problem”, the sequence of offers is a random sample from a single known distribution. We present an extension of this problem in which the sequential offers are random variables but from multiple independent distributions. Each distribution function represents a class of investment or offers. Offers appear without any specified order. The objective is...
متن کاملThe roles of EPIYA sequence to perturb the cellular signaling pathways and cancer risk
Abstract It was shown that several pathogenic bacterial effector proteins contain the Glu-Pro-Ile-Tyr-Ala (EPIYA) or a similar sequence. These bacterial EPIYA effectors are delivered into host cell via type III or IV secretion system, where they undergo tyrosine phosphorylation at the EPIYA sequences, which triggers interaction with multiple host cell SH2 domain-containing proteins and thereby...
متن کاملDesign and optimization of poly lactic acid/bioglass composite screw for orthopedic applications
However, problems such as osteoporosis due to high elasticity of metals relative to bones, and local infections and systemic problems caused by releasing metallic ions have motivated research on replacing metallic screws with non metallic ones. In this study, the composite containing poly-l-lactic acid and bioactive glass fibers were considered for the design of the screw using ABAQUS software ...
