WebbThe simplest way to prevent overfitting is to start with a small model. A model with a small number of learnable parameters (which is determined by the number of layers and the number of units per layer). In deep learning, the number of learnable parameters in a model is often referred to as the model’s “capacity”.

While the use of large mini-batches increases the available computational parallelism, small batch training has been shown to provide improved generalization performance and allows a significantly smaller memory … Webb6 aug. 2024 · A smaller learning rate may allow the model to learn a more optimal or even globally optimal set of weights but may take significantly longer to train. At extremes, a learning rate that is too large will result in weight updates that will be too large and the performance of the model (such as its loss on the training dataset) will oscillate over …

WebbTraining with large batch size immediately increases parallelization, thus has the potential to decrease learning time. Many efforts have been made to parallelize SGD for Deep Learning (Dean et al., 2012; Das et al., 2016; Zhang et al., 2015), yet the speed-ups and scale-out are still limited by the batch size.
