Higher order co-occurrences play a key role in the effectiveness of systems used for text mining. A wide variety of applications use techniques that explicitly or implicitly employ a limited degree of transitivity in the co-occurrence relation. In this work we show use of higher orders of co-occurrence in the Singular Value Decomposition (SVD) algorithm and, by inference, on the systems that re...

A dual probability model is constructed for the Latent Semantic Indexing (LSI) using the cosine similarity measure. Both the document-document similarity matrix and the term-term similarity matrix naturally arise from the maximum likelihood estimation of the model parameters, and the optimal solutions are the latent semantic vectors of of LSI. Dimensionality reduction is justiied by the statist...

Abstract: Tamper resistance of LSI chips against physical attacks is studied from the viewpoint of LSI failure analysis. Laying stress on the basic physical phenomena generated in LSI chips under operating conditions, we outline today’s failure analysis techniques with application to evaluating or testing tamper resistance of LSI chips. We give some results from our case study on inactivation o...

We describe an approach to information retrieval using a technique which combines two existing well-known information retrieval techniques: traditional vector space retrieval and Latent Semantic Indexing (LSI). The technique described in this paper assigns a query to document similiarity that is a weighted average of the similarity scores obtained by LSI and traditional vector space retrieval. ...

Latent Semantic Indexing (LSI) has been successfully applied to information retrieval and classification. LSI can deal with the problems of polysemy and synonymy, and can reduce noise in the raw document-term matrix. However, LSI may ignore important features for some small categories because they are not the most important features for all the document collection. In this paper, we describe a ...

This paper discusses Mixed Signal LSI technology with embedded power transistors. Trends in Mixed Signal LSI technology are explained at first. Mixed signal LSI technology has proceeded with the help of fine fabrication technology and SOI technology. The BEOL transistor is a new development, which uses InGaZnO (IGZO) as its TFT channel material. The BEOL transistor is one future device which en...
