Confidence Decision Trees via Online and Active Learning for Streaming (BIG) Data

no code implementations12 Apr 2016 Rocco De Rosa

We fill this gap by deriving accurate confidence intervals to estimate the splitting gain in decision tree learning with respect to three criteria: entropy, Gini index, and a third index proposed by Kearns and Mansour.

Active Learning for Online Recognition of Human Activities from Streaming Videos

no code implementations11 Apr 2016 Rocco De Rosa, Ilaria Gori, Fabio Cuzzolin, Barbara Caputo, Nicolò Cesa-Bianchi

Recognising human activities from streaming videos poses unique challenges to learning algorithms: predictive models need to be scalable, incrementally trainable, and must remain bounded in size even when the data stream is arbitrarily long.

Active Learning

Online Open World Recognition

no code implementations8 Apr 2016 Rocco De Rosa, Thomas Mensink, Barbara Caputo

Recent attempts, like the open world recognition framework, tried to inject dynamics into the system by detecting new unknown classes and adding them incrementally, while at the same time continuously updating the models for the known classes.

The ABACOC Algorithm: a Novel Approach for Nonparametric Classification of Data Streams

no code implementations20 Aug 2015 Rocco De Rosa, Francesco Orabona, Nicolò Cesa-Bianchi

Stream mining poses unique challenges to machine learning: predictive models are required to be scalable, incrementally trainable, must remain bounded in size (even when the data stream is arbitrarily long), and be nonparametric in order to achieve high accuracy even in complex and dynamic environments.
