Fine tuning neural network hyperparameters
WebExamples: Comparison between grid search and successive halving. Successive Halving Iterations. 3.2.3.1. Choosing min_resources and the number of candidates¶. Beside factor, the two main parameters that influence the behaviour of a successive halving search are the min_resources parameter, and the number of candidates (or parameter combinations) … WebIn spite of being trained using images with entirely different domain, these networks are flexible to adapt to solve a problem in a different domain too. Transfer learning involves fine-tuning a pre-trained network with optimal values of hyperparameters such as learning rate, batch size, and number of training epochs.
