Finetunen

Finetunen is a verb used in Dutch and other Germanic languages to describe the act of making small, precise adjustments to improve the performance, fit, or accuracy of a system. The term is derived from the English phrasal verb fine-tune and has been adopted into several languages as a single-word verb to express the same idea. It is commonly employed in both technical and non-technical contexts.

In technology and data science, finetunen refers to the process of adapting a pre-trained model to a specific task or domain by continuing training on a targeted dataset. This often involves unfreezing certain layers, choosing a smaller learning rate, and adjusting regularization, with careful monitoring of validation performance to avoid overfitting. Finetunen enables leveraging broad prior knowledge while tailoring the model to a niche application without training from scratch.

In other contexts, finetunen can describe precise calibration or optimization tasks, such as tuning musical instruments, calibrating measurement equipment, or adjusting configuration parameters in software and hardware systems to reach optimal performance.

Related terms include fine-tune and fine-tuning. The concept is commonly associated with calibration, optimization, and transfer learning, and its usage reflects a preference for small, deliberate adjustments over broad, sweeping changes.
