Active learning for class imbalance problem

Active learning with uncertainty sampling for large scale activity recognition in smart homes Alemdar, Hande; Ersoy, Cem (2017-01-01) One of the major problems faced by automated human activity recognition systems is the scalability. Since the probabilistic models employed in activity recognition require labeled data sets for adapting themselves to different users and environments, redeploying these systems in different settings becomes a bottleneck. In order to handle this problem in a cost effective and user friendly way, uncertainty sampling based active learning method is proposed. With active learning, it is possible to reduce the an...

Active neuro-adaptive control of a smart beam having uncertainties in structural dynamics Akın, Onur; Şahin, Melin; Department of Aerospace Engineering (2015) In this thesis, an active vibration suppression of a smart beam having piezoelectric sensor and actuators is investigated by designing separate controllers comprising a linear quadratic regulator and a neural network. At first, design of a smart beam which consists of a cantilever aluminum beam with surface bonded piezoelectric patches and a designed mechanism having a micro servomotor with a mass attached arm for obtaining variations in the frequency response function are presented. Secondly, the frequency...
Active motor damping strategy for driveline vibrations of a hybrid electric vehicle during ABS operation Bayar, Kerem (2022-01-01) Torsional drivetrain vibrations in hybrid and electric drivetrains, which occur during traction and braking control, are commonly encountered. This problem occurs mainly due to the weak damping characteristic of the hybrid/electric drivetrain and the fast time response characteristics of the electric motor. An active motor damping (AMD) control algorithm for a hybrid electric vehicle, considering ABS braking maneuvers on different road conditions, is developed in this work. The control problem is structured...
