The phrase "approximate the performance of" is correct and usable in written English.
You can use it when discussing the evaluation or estimation of how well something functions in comparison to a standard or expected outcome.
Example: "The new algorithm was designed to approximate the performance of existing models while improving efficiency."
Alternatives: "estimate the effectiveness of" or "simulate the performance of".
A more convincing argument made by Vanguard presented a comparison of a hypothetical $10,000 investment in the Vanguard 500 Index fund with a $10,000 investment in the iShare 500, both of which are intended to approximate the performance of the S.& P. 500.
It is shown that the distributed heuristic algorithm can approximate the performance of COMMAN closely.
In the noisier conditions, the networks trained with modulation frequency features derived from the multi-condition training data approximate the performance of the stacks of nine extended PLP features.
A comparison of the results of the language-independent QbE STD system with those of the language-dependent text-based STD system presented in this paper shows that it is clear that there is still ample room for improvement to approximate the performance of a language-independent QbE STD system to that of a language-dependent text-based STD system.
However, when comparing the QbE STD results with the results of the text-based DNN STD system presented in this paper, it is clear that there is still ample room for improvement to approximate the performance of QbE STD to that of text-based STD.
Based on our results in Experiment 1 (and corroborated by those in Experiment 2) and the primarily horizontal shift observed between the functions for older and younger participants, adding 1.48 arcmin of blur or 11.5% noise contrast will approximate the performance of an older participant (Fig. 4).
In our evaluation, we first show that the schemes proposed for first formulation outperform a blind round-robin scheduler and approximate the performances of an ideal scheduler that involves an impractical exhaustive exploration of all possible schedules.
For the case evaluated with recycle intercooling, the new design achieved significant packing reductions (>50%) compared to a simple intercooling design and approximated the performance of an isothermal column.
However, as the next lemma asserts, with high probability, the graph induced by S has cliques of at most logarithmic size (in K), hence a polynomial time algorithm which searches for bounded size cliques can approximate closely the performance of the best greedy scheme, and a sub-exponential time algorithm is asymptotically optimal.
Approximated evaluations of the performance of the WL receiver are available in [11] for a QAM constellation and in [3] for a PAM constellation in the presence of a PAM cochannel interference.
The axially symmetric profiles obtained approximate "holey" annular structures, the performance of which can be validated using existing waveguide analysis techniques.
