We compared the term- and document-centric static index pruning approaches as described in the literature and investigate their sensitivity to the scoring functions employed during the pruning and actual retrieval stages.

A Theoretical Analysis of Multi-Modal Representation Learning with Regular Functions
Vural, Elif (2021-01-07)
Multi-modal data analysis methods often learn representations that align different modalities in a new common domain, while preserving the within-class compactness and within-modality geometry and enhancing the between-class separation. In this study, we present a theoretical performance analysis for multi-modal representation learning methods. We consider a quite general family of algorithms learning a nonlinear embedding of the data space into a new space via regular functions. We derive sufficient condit...
Dynamic performances of kinematically and dynamically adjustable planar mechanisms
İyiay, Erdinç; Soylu, Reşit; Department of Mechanical Engineering (2003)
In this thesis, the dynamic performances of kinematically and dynamically adjustable planar mechanisms have been investigated. An adjustable mechanism is here defined to be a mechanism where some of the kinematic and/or dynamic parameters are changed in a controlled manner in order to optimize the dynamic behaviour of the mechanism in spite of variable operating conditions. Here, variable operating conditions refer to variable load(s) on the mechanism and/or variable desired input motion. The dynamic behavi...
A verification approach for dynamics of metamodel based conceptual models of the mission space
Eryılmaz, Utkan; Bilgen, Semih; Department of Information Systems (2011)
Conceptual models were introduced in the simulation world in order to describe the problem domain in detail before any implementation is attempted. One of the recent approaches for conceptual modeling of the military mission space is the KAMA approach which provides a process description, a UML based notation, and a supporting tool for developing conceptual models. The prominence of the approach stems from availability of guidance and applications in real life case studies. Although the credibility of a con...
Reducing inconsistencies in intuitionistic 2-way adaptive fuzzy control systems
Gurkan, E; Erkmen, Aydan Müşerref; Erkmen, İsmet (2000-08-30)
Our objective in this paper is to model and reduce inconsistency in expert knowledge for our proposed 2-way adaptive fuzzy system that makes use of intuitionistic fuzzy sets. Intuitionistic fuzzy sets model an interval valued distribution of information in the adaptive control architecture with the necessity at the lower bound as the degree of membership functions and the possibility at the upper bound as the complement of the degree of nonmembership functions. Uncertainty is modelled as the width of this i...
Algorithms for within-cluster searches using inverted files
Altıngövde, İsmail Sengör; Ulusoy, Ozgur (2006-01-01)
Information retrieval over clustered document collections has two successive stages: first identifying the best-clusters and then the best-documents in these clusters that are most similar to the user query. In this paper, we assume that an inverted file over the entire document collection is used for the latter stage. We propose and evaluate algorithms for within-cluster searches, i.e., to integrate the best-clusters with the best-documents to obtain the final output including the highest ranked documents ...
