NettetEffective batch size = number of GPUs * --batch_size * --update_freq. So in the above example, the effective batch size is 8*32*2 = 512. The three arguments need to be adjusted together in order to keep the total batch size unchanged. Gradient accumulation: if your GPU memory is limited (i.e., OOM issues), you can reduce --batch size and ... Nettet17. aug. 2024 · Fine-tuning is the process in which the parameters of a trained model must be adjusted very precisely while we are trying to validate that model taking into account a small data set that does not belong to the train set.. That small validation data set comes from the same distribution as the data set used for the training of the model. …

Nettet21. feb. 2024 · It is well known that fine-tuning leads to better accuracy in-distribution (ID). However, in this paper, we find that fine-tuning can achieve worse accuracy than linear probing out-of-distribution (OOD) when the pretrained features are good and the distribution shift is large.
