Artificial Intelligence

As one of the research directions at OLIVES Lab @ Georgia Tech, we focus on recognizing textures and materials in real-world images, which plays an important role in object recognition and scene understanding. Aiming at describing objects or scenes with more detailed information, we explore how to computationally characterize apparent or latent properties (e.g. surface smoothness) of materials, i.e., computational material characterization, which moves a step further beyond material recognition.

This dataset was used and described in detail in the following publication.

In this paper, a sliding mode adaptive control strategy is proposed to improve driving comfort effectivelyunder the conditions of ensuring driving safety and limited suspension travel.Considering the non-linear characteristics of the asymmetric single-rod hydraulic actuator with a small occupied volume, the uncertainty of the parameters of the body mass, the friction of the suspension components and the unmodeled dynamics of the system, a half-vehicle active suspension model wasestablished. The adaptive law is designed to combine sliding mode and adaptive algorithms.
