split up batches on multiple GPUs or multiple computers even to achieve even more significant speed ups with this training process now the last topic I want to address is that of overfitting and this is also known as the problem of generalization in machine learning and it's actually not unique to just deep learning but it's a fundamental problem of all of machine learning now ideally in machine learning we want a model that will approximate or estimate our data or accurately describes our data let's say like that said differently we want to
