The phrase "a certain input" is correct and usable in written English.
It can be used when referring to a specific but unspecified input in a context, such as programming, data analysis, or general discussions about processes.
Example: "The system requires a certain input to function properly, which can vary depending on the user's needs."
Alternatives: "a specific input" or "an unspecified input".
Programmers give programs a set of capacities, usually in the form of functions, a certain input and (sometimes) a specified output.
Each NOR operation with a certain input combination was repeated for 10 cycles.
For all of our senses, when a certain input is constant we gradually get used to it.
This should quell the randomness so that given a certain input, the cluster will produce the right answer.
From a policy perspective, this is still a useful estimate of the effect of providing a certain input.
However, for a certain input x, if d is alternatively chosen, the iterative training process would finally lead to different output y.
Subspace-based order identification determines the order as the number of principle eigenvalues (or singular values) of a certain input-output data matrix.
Considering a certain stimulus as an input signal to the system and mRNA or protein levels as outputs, the connecting network may include interactions between signal transduction intermediates: transcription factors and target genes.
To carry out a sensitivity analysis, certain input data were altered and the effect on the final results was observed, which allowed for different scenarios to be generated and may consequently call for further discussion.
The reduced sensitivity of gene 3 when p decreases towards 1 can be seen as a consequence of the fact that when the sigmoids in the rate equation for x3 are slackened, a certain variation in the inputs gives smaller variation in the response.
Experimental design techniques allow modeling of process input parameters and output response, and provides a mathematical relationship that is able to predict a desired response at certain input parameters.
