Making Retrieval Faster Through Document Clustering

David Grangier, Alessandro Vinciarelli

This work addresses the problem of reducing the time between query submission and results output in a retrieval system. The goal is achieved by considering only a database fraction as small as possible during the retrieval process. Our approach is based on ...

Noisy Text Clustering

David Grangier, Alessandro Vinciarelli

This work presents document clustering experiments performed over noisy texts (i.e. text that have been extracted through an automatic process like speech or character recognition). The effect of recognition errors on different clustering techniques is mea ...

Effect of Recognition Errors on Text Clustering

David Grangier, Alessandro Vinciarelli

This paper presents clustering experiments performed over noisy texts (i.e. texts that have been extracted through an automatic process like character or speech recognition). The effect of recognition errors is investigated by comparing clustering results ...

Single-linkage clustering for optimal classification in piecewise affine regression

Giancarlo Ferrari Trecate

When performing regression with piecewise affine maps, the most challenging task is to classify the data points, i.e. to correctly attribute a data point to the affine submodel that most likely generated it. In this paper, we consider a regression scheme s ...

A clustering technique for the identification of piecewise affine and hybrid systems

Giancarlo Ferrari Trecate

We propose a new technique for the identification of discrete-time hybrid systems in the Piece-Wise Affine (PWA) form. This problem can be formulated as the reconstruction of a possibly discontinuous PWA map with a multi-dimensional domain. In order to ach ...

Self-Organizing-Maps With BIC For Speaker Clustering

A new approach is presented for clustering the speakers from unlabeled and unsegmented conversation, when the number of speakers is unknown. In this approach, each speaker is modeled by a Self- Organizing-Map (SOM). For estimation of the number of clusters ...

A clustering technique for the identification of Piecewise Affine Systems

Giancarlo Ferrari Trecate

We propose a new technique for the identification of discrete-time hybrid systems in the Piece-Wise Affine (PWA) form. The identification algorithm proposed in (Ferrari-Trecate et. al., 2000) is first considered and then improved under various aspects. Mea ...

First-principles studies of Cu clusters

Alfredo Pasquarello, Roberto Car

Equilibrium geometries and electronic properties of neutral and anionic Cu-n (n = 2, 10) clusters are determined via first-principles calculations which treat s and d electrons on an equal footing. We find cluster shapes similar to those reported in the li ...

Significant similarity and dissimilarity in homologous proteins

Philipp Bucher

Common practice emphasizes significant sequence similarities between different members of protein families. These similarities presumably reflect on evolutionary conservation of structurally and functionally essential residues. The nonconserved regions, on ...
