Dynamic Instance-Wise Classification in Correlated Feature Spaces
Yasitha Warahena Liyanage, Daphney-Stavroula Zois, Charalampos Chelmis
In a typical supervised machine learning setting, the predictions on all test instances are based on a common subset of features discovered during model training. However, using a…
On-the-Fly Joint Feature Selection and Classification
Yasitha Warahena Liyanage, Daphney-Stavroula Zois, Charalampos Chelmis
Joint feature selection and classification in an online setting is essential for time-sensitive decision making. However, most existing methods treat this coupled problem independe…
Controlled Sensing: A Myopic Fisher Information Sensor Selection Algorithm
Daphney-Stavroula Zois, Urbashi Mitra
This paper considers the problem of state tracking with observation control for a particular class of dynamical systems. The system state evolution is described by a discrete-time,…
Nonlinear POMDPs for Active State Tracking with Sensing Costs
Daphney-Stavroula Zois, Urbashi Mitra
Active state tracking is needed in object classification, target tracking, medical diagnosis and estimation of sparse signals among other various applications. Herein, active state…
Active Classification for POMDPs: a Kalman-like State Estimator
Daphney-Stavroula Zois, Marco Levorato, Urbashi Mitra
The problem of state tracking with active observation control is considered for a system modeled by a discrete-time, finite-state Markov chain observed through conditionally Gaussi…
