(Number of batches * Number of images in a single batch = Total number of data set) => (2 * 5 = 10).Įnough of this child’s play, let’s get bigger, if you have a brain scan image data set containing 100000 images, we can convert it into 3125 batches where each batch has 32 images in it. You can break your data set into batches, that is, if you have a data set containing ten brain scan images, you can split your data set into two batches where each batch has five images, Guys, don’t get disheartened, there is a better method for you. ![]() So, if you load the whole data set into the memory, the training speed of the model will be very slow because you are using a lot of memory in your CPU which is very inefficient. You may be having a data set of huge size, say, a million brain scan images. You are just starting to build your dream startup as said earlier, so you might not be having a high end GPU or CPU. You can load a sample set of data into the memoryĭidn’t understand a thing, right? Let me break it down for you. You can either load the whole data set to the memory at once orĢ. WHEN and WHY to use batch ?īefore loading the data set to the memory we have two options -ġ. Now is the right time to understand what is “batch”. Seems like a great idea to build a startup, right ?įirst thing is to collect the required data, for now assume that you have already done that and now you are ready with your data. You have got a brilliant idea to build a deep learning model to detect brain tumor and other abnormalities of brain from MRI scans. Hmm, this must be definitely explained through an example. No more delays, let’s jump into it right away. Whether the answer is a Yes or No, today you will learn about batches and why you should even consider using it in your machine learning pipeline. Hey there, have you ever come across the term “batch” while loading data sets ? ![]()
