Compressive Mining: Fast and Optimal Data Mining in the Compressed Domain
Michail Vlachos, Nikolaos Freris, Anastasios Kyrillidis
Real-world data typically contain repeated and periodic patterns. This suggests that they can be effectively represented and compressed using only a few coefficients of an appropri…
Scalable sparse covariance estimation via self-concordance
Anastasios Kyrillidis, Rabeeh Karimi Mahabadi, Quoc Tran-Dinh +1
We consider the class of convex minimization problems, composed of a self-concordant function, such as the metric, a convex data fidelity term and, a regulari…
Non-uniform Feature Sampling for Decision Tree Ensembles
Anastasios Kyrillidis, Anastasios Zouzias
We study the effectiveness of non-uniform randomized feature selection in decision tree classification. We experimentally evaluate two feature selection methodologies, based on inf…
