Experimental validation

Definition

Experimental validation refers to the process of verifying the accuracy and reliability of a theoretical model or system through practical experiments and observations. This process is crucial in assessing whether the predictions made by a model hold true when applied to real-world scenarios, allowing for adjustments and improvements to be made based on empirical evidence.
