The phrase "a coarse approximation" is correct and usable in written English.
It can be used when referring to an estimate or calculation that is rough or not precise.
Example: "The scientist provided a coarse approximation of the results, acknowledging that further research was needed for accuracy."
Alternatives: "a rough estimate" or "a rough approximation".
This idea of using a coarse approximation of a problem to approximate its solution, (and recursively using a yet coarser approximation of the coarse problem) is used in a variety of fast algorithms; we will see it again when we discuss graph partitioning.
Humans somehow represent a coarse approximation of the physics in real-time under perceptual uncertainty.
The world of food and beverage manufacturing, Cohen says, is still oriented around "the predominant demographic", the flavors of things tailored to please a coarse approximation of majority appetites.
However, the surface manufactured by such an elastic bucking is only a coarse approximation of a parabola, which is not precise enough for meeting the demand of a high quality concentrator.
"It's intriguing to me that these software models, which are based on such a coarse approximation of neurons and have very few biologically based constraints, not only perform well in a number of difficult pattern-recognition problems they also seem to be predicting some of the properties of actual neurons in the visual cortex of monkeys," Poggio explains.
The width of the burst was thus 13 samples or 65ms and its waveform was a coarse approximation to a Gaussian.
The physical simulation uses a volume mesh comprised of quadratic tetrahedra, which are constructed from a coarser approximation of the detailed surface.
This is because, by decreasing the DWR, the watermark amplitude gets larger and the LOD derived by truncating the second and higher orders of Taylor's series results in a coarser approximation of the ML decoder.
This initial polygon can be considered as a very coarse approximation to the final surface.
A z-coordinate is also available, which is defined as the maximum of the width and height of the object and can be used as a (very) coarse approximation of distance.
Consequently, the partitioning into loops and stems must be seen as only an relative coarse approximation to model rRNA sequences.
