![]() Once this has been done, other late layers in the model can be set as ‘trainable=True’ so that in further SGD epochs their weights can be fine-tuned for the new task too.The new output layer that is attached to the model is then trained to take the lower level features from the front of the network and map them to the desired output classes, using SGD.Replaces the output layer, originally trained to recognize (in the case of Imagenet models) 1,000 classes, with a layer that recognizes the number of classes you require.This is called fine-tuning because it slightly adjusts the more abstract representations of the model being reused, in order to make them more relevant for the problem at hand.įine-tuning is a process to take a network model that has already been trained for a given task and makes it perform a second similar task.Īssuming that the original task is similar to the new task, using a designed and trained network allows us to take full advantage of the feature extraction that occurs in the top layer of the network without having to develop a feature extraction network from scratch. This requires fine-tuned regulation of brain systems that enable rapid responses to changes in the environment, such as those involved in sleep, wakefulness, stress, and reward-seeking.A widely used technique for model reuse, complementary to feature extraction, is fine-tuning.įine-tuning involves unfreezing some layers of the top layer of the frozen model library for feature extraction, and jointly training the newly added part of the model (in this case, a fully connected classifier) and these top layers. (Interplay between mitochondria and the nucleus may have implications for changing cell’s ‘batteries’, University of Cambridge) However, esearchers compared mitochondrial and nuclear DNA from tens of thousands of people and found that mitochondria may be fine-tuned to the nucleus. (Gut bacteria may control movement, National Institutes of Health) (Seasonality of bird migration responds to environmental cues, NSF)Īdditional experiments showed that Xi may regulate movement by fine-tuning levels of certain carbohydrates, such as trehalose, which is the main sugar found in flies and is similar to mammalian glucose. Researchers say the migration indexes can help address a gap in scientists' knowledge about the cues birds use to fine-tune migration timing in response to climate. (Developing Insulin-Producing Cells to Treat Diabetes, NIH) They eventually fine-tuned a protocol that involved 5 different growth media and 11 different factors.
