To speed up the estimation process, different two-stage estimators are proposed where the first stage estimates a coarse TOA and the second stage refines the result [30, 31].
The first stage, the initialization stage, produces a qualitative network node graph, while the second stage refines the result by using a spring model, which is the most relevant to our algorithm.
The estimation process contains two stages: a conventional Kalman filter is applied in the first stage; the second stage refines the estimates in an iterative learning fashion, leading to a gradual improvement on the estimation performance.
The process focuses on the separation of roles during the design stage: domain experts use a basic editor that allows them to define the categories and factors that will be involved in the FIS in natural language, while knowledge engineers at a later stage refine these elements using a more advanced editor.
The second stage refines this initial estimate by matching pixels locally in high-contrast, anatomically relevant regions of the Gabor image using local rigid transformations.
But April's plunge was scary, and instead of taking a flier on just about any plausible idea out there venture capital firms are re-emphasizing grunt work -- shepherding companies through the difficult early stages, refining business models, building value.
GOG.com is offering up an advance on royalties that definitely isn't common practice among digital games storefronts, which it says will help indie devs do some end-stage refining on game production.
Refined pulp is typically conveyed to a second stage of refining, where we have found significant improvements in enzyme hydrolysis efficiency.
Lines (6 - 7) show the stage of refining clusters.
Egyptian wall reliefs from 2300 bc show gold in various stages of refining and mechanical working.
He led an American group to Paris in 1968 with a proposal to stop the war, but on stage he refined his anger into the blistering family comedy of The Price (1968), and never set a play in Vietnam.
