Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model.
… use similarity measures based on geometric models of similarity. However, most human similarity judgment data violate the metric axioms of these models. Tversky's (1977) contrast model, which defines similarity as a feature contrast task and equates the degree of similarity of two stimuli to …

Reinforcement learning in network control
… and do not offer performance guarantees. In contrast, model-based learning methods offer performance guarantees, but can only be applied with bounded state spaces. In the thesis, we propose to use model-based reinforcement learning. By applying Lyapunov analysis, our algorithm can be applied …

A study of diapycnal mixing in the Southern Ocean using a tracer release experiment and numerical models
… of mixing in the Southern Ocean. Here numerical models are used to advect and diffuse a tracer in the Antarctic Circumpolar Current, beginning in the Southeast Pacific and progressing through Drake Passage, and model outputs are then compared with observations from the DIMES tracer. The …

Evaluation and improvement of optical remote sensing methods in monitoring particulate matter emissions and plume opacity
… opacity using DOM software. There are two DOM models that were previously developed by Du (2007), namely: 1) the contrast model that requires a plume passing in front of and near one of two co-located contrasting backgrounds; and 2) the transmission model that requires a plume passing in front …
