WebNov 9, 2024 · $\begingroup$ As I explained, you shuffle your data to make sure that your training/test sets will be representative. In regression, you use shuffling because you want to make sure that you're not training only on the small values for instance. Shuffling is mostly a safeguard, worst case, it's not useful, but you don't lose anything by doing it. The Fisher–Yates shuffle is an algorithm for generating a random permutation of a finite sequence—in plain terms, the algorithm shuffles the sequence. The algorithm effectively puts all the elements into a hat; it continually determines the next element by randomly drawing an element from the hat until no elements remain. The algorithm produces an unbiased permutation: every perm… WebJan 26, 2008 · In a shuffle sharded system, a single customer is still assigned to a single shard of two workers, but that shard actually overlaps with 12 other shards (6 other options for worker 1, 6 other options for worker 2).
