The phrase "a more robust alternative" is correct and usable in written English.
You can use it when discussing options or solutions that are stronger or more effective than others.
Example: "After reviewing the available options, we found that a more robust alternative would be to implement a new software system."
Alternatives: "a stronger option" or "a more effective choice".
Traits are a more robust alternative to multiple inheritance and enable object composition and reuse.
Copulas are applied to model intersite dependence and trimmed L-moments as a more robust alternative to ordinary L-moments.
The resulted model, combining the merits of DBN and ESN, provides a more robust alternative to conventional deep neural networks for the superior prediction capacity.
This provides a more robust, alternative verification of equivalence ratio, based on measured air flow, than the phi meter used in other reported work.
To our best knowledge, this is the first systematic model attempting to introduce the deep learning methodology to the ESN modeling, which provides a more robust alternative to the conventional shallow ESNs.
As a more robust alternative I would suggest something I call Time Out.
The use of SUVpeak, which is defined as the mean value within an ROI centred on the area with the highest uptake, has been reported as a slightly more robust alternative for assessing the most metabolically active part of a tumour [ 19].
This paper presents an extensive evaluation of electroless NiPd and NiPdAu bond pads that offer a much more robust alternative to the standard Al pad finish.
SVD is a numerically more robust alternative solution to PCA.
A generally more robust alternative is the direct comparison of sister species, with each pair of sister species being a phylogenetically independent data point (tip contrasts), but in most data sets there are not sufficient sister species pairs for adequate statistical analysis [ 22].
As a third and more robust alternative, we will also consider a Rule-based strategy described in [34], which makes use of Portuguese grammar rules to enforce constituents agreement and sentence linearisation.
