Basic Principles of the RELAX Estimation Algorithm

Witryna7 paź 2012 · Relaxing an edge, (a concept you can find in other shortest-path algorithms as well) is trying to lower the cost of getting to a vertex by using another vertex. You are calculating the distances from a beginning vertex, say S, to all the other vertices. At some point, you have intermediate results -- current estimates. WitrynaMany feature extraction methods, such as CLEAN/RELAX-based algorithms, are built on this hypothesis and so it is currently used in assisted/automatic target recognition algorithms (ATR). However, this simple model cannot describe the variability of the signatures one can observe in image databanks. ...

WitrynaImplementation of the RELAX algorithm Abstract:This correspondence presents a zoom-FFT based RELAX algorithm for estimating sinusoidal parameters in the presence of unknown colored noise. The amount of computations required by this algorithm is much less than the original zero-padding FFT based RELAX. Witryna11 cze 2016 · The meaning of slack is that, when it's zero, the left-hand side of the constraint equals the right, and when it's negative, the constraint is violated. Here, the slack for (*) is d [u] + w [u->v] - d [v]. Once we've defined slack, RELAX is the procedure that relieves tension (i.e., negative slack) on (*). Share.
