The phrase "a validation exercise" is correct and usable in written English.
It can be used when referring to an activity or process designed to confirm the accuracy or effectiveness of something, often in a testing or evaluation context.
Example: "The team conducted a validation exercise to ensure that the new software met all the required specifications."
Alternatives: "a verification process" or "an assessment activity".
In order to validate the instruments that were translated, a validation exercise was carried out by the expert team.
"[This is] partly because, in the past, governments of all colours have tended to use consultation exercises as a way of getting people to agree what they have already decided to do, in other words a validation exercise.
The model is easy to initialize with field data and we report favorable results from a validation exercise at Heineken Brewery.
Then the measured RLR rates have been evaluated and compared to the modelling results as a validation exercise improving and extending the prediction capability of the proposed model.
Finally, a validation exercise is presented in which the simulator's inputs were specified to represent the University of Delaware's fuel cell hybrid transit vehicle and "driven" using an actual drive cycle acquired from it.
A validation exercise performed on simulated discrete fracture networks demonstrates that the calculated P32 values provide unbiased predictions of the true P32, at both global and local scales, and can therefore be used as experimental data for spatial interpolation purposes.
To validate the model, new experimental data were collected and used to create an external set, as a second validation set (a first validation exercise had been done just after model development).
A sensitivity analysis and a small validation exercise were undertaken to assess the impact of missing data on the estimate of mobility.
Apart from an initial validation exercise for a laminated composite plate with a hole where no or little damage occurs, we also use numerical simulations on mode I, mode II, and mixed mode delamination cases in order to assess the performance of our model by benchmarking it against available experimental evidence.
A final validation exercise involved replication of a published case control study that examined use of nonsteroidal anti-inflammatory drugs (NSAIDs) and the risk of first-time acute myocardial infarction (AMI) in raw CPRD data and the CPRD CDM.
In addition, a small validation exercise was undertaken by cross-referencing a sample of randomly selected cases with the UK National Health Service National Strategic Tracing Service NSTSS) records.
