Fine-tuning may refer to: *

Fine-tuning (deep learning) In deep learning, fine-tuning is an approach to transfer learning in which the parameters of a pre-trained neural network model are trained on new data. Fine-tuning can be done on the entire neural network, or on only a subset of its layers, in w ...

Fine-tuning (physics) In theoretical physics, fine-tuning is the process in which parameters of a model must be adjusted very precisely in order to fit with certain observations. Theories requiring fine-tuning are regarded as problematic in the absence of a known mec ...

Fine-tuned universe The fine-tuned universe is the hypothesis that, because "life as we know it" could not exist if the fundamental physical constants, constants of nature – such as the electron charge, the gravitational constant and others – had been even ...
