Deep Open-Set Recognition for Silicon Wafer Production Monitoring

no code implementations30 Aug 2022 Luca Frittoli, Diego Carrera, Beatrice Rossi, Pasqualina Fragneto, Giacomo Boracchi

Here we address WDM monitoring as an open-set recognition problem to accurately classify WDM in known categories and promptly detect novel patterns.

Nonparametric and Online Change Detection in Multivariate Datastreams using QuantTree

1 code implementation30 Aug 2022 Luca Frittoli, Diego Carrera, Giacomo Boracchi

Like many change-detection algorithms, QT-EWMA builds a model of the data distribution, in our case a QuantTree histogram, from a stationary training set.

QuantTree: Histograms for Change Detection in Multivariate Data Streams

no code implementations ICML 2018 Giacomo Boracchi, Diego Carrera, Cristiano Cervellera, Danilo Macciò

Our experiments show that the proposed histograms are very effective in detecting changes in high dimensional data streams, and that the resulting thresholds can effectively control the false positive rate, even when the number of training samples is relatively small.

Change Detection in Multivariate Datastreams: Likelihood and Detectability Loss

no code implementations16 Oct 2015 Cesare Alippi, Giacomo Boracchi, Diego Carrera, Manuel Roveri

We address the problem of detecting changes in multivariate datastreams, and we investigate the intrinsic difficulty that change-detection methods have to face when the data dimension scales.
