Research Expertise:
The overarching scope of Dr. Polikar's research is development of fundamental computational intelligence approaches and statistical learning models for challenging problems in machine learning. Under this main umbrella, his work has focused on four primary areas:
- adversarial machine learning with a focus on versatile defensive mechanisms against a broad spectrum of malicious attacks;
- incremental (continuous) learning from streaming or batches of data obtained from dynamic, nonstationary, drifting, uncertain or even adversarial environments where the learning model may possibly be under malicious attack;
- development and adaptation of ensemble based approaches for a broad spectrum of underexplored areas of machine learning, such as missing data, data fusion and concept drift in recurrent nonstationary environments, and
- applications of above mentioned approaches to practical problems, such as early diagnosis of neurological disorders or species identification and classification in metagenomics.
