Each index is used to index into your Dataset to grab the data (x, y). You can ignore this for now, but DataLoaders also have a batch_sampler which returns the indices for each batch in a list if batch_size is greater than 1.. Don't worry if this is a bit confusing, it'll …

Reservoir sampling is a family of randomized algorithms for choosing a simple random sample, without replacement, of k items from a population of unknown size n in a single pass over the items. The size of the population n is not known to the algorithm and is typically too large for all n items to fit into main … See more Suppose we see a sequence of items, one at a time. We want to keep ten items in memory, and we want them to be selected at random from the sequence. If we know the total number of items n and can access the items … See more If we associate with each item of the input a uniformly generated random number, the k items with the largest (or, equivalently, smallest) … See more Suppose one wanted to draw k random cards from a deck of cards. A natural approach would be to shuffle the deck and then take the top k cards. In the general case, the shuffle … See more Reservoir sampling makes the assumption that the desired sample fits into main memory, often implying that k is a constant … See more If we generate $${\displaystyle n}$$ random numbers $${\displaystyle u_{1},...,u_{n}\sim U[0,1]}$$ independently, then the indices of the smallest $${\displaystyle k}$$ of them is a uniform sample of the k-subsets of $${\displaystyle \{1,...,n\}}$$ See more This method, also called sequential sampling, is incorrect in the sense that it does not allow to obtain a priori fixed inclusion probabilities. Some applications require items' … See more Probabilities of selection of the reservoir methods are discussed in Chao (1982) and Tillé (2006).
