Sklearn shuffle seed

Webb31 okt. 2024 · The shuffle parameter is needed to prevent non-random assignment to to train and test set. With shuffle=True you split the data randomly. For example, say that … Webbnp.random.seed(42) before you shuffle the array at . np.random.shuffle(array) The reason for this is without seeding np.shuffle will create a different result each time. Thus when you feed the array into the model it will return a different result. Seeding allows you to shuffle it the same each time, thus creating reproducible results.

Webbrandomstate,很多函数里面都有这一个param,相当于随机数的seed.是为了可重现，一般都要和shuffle搭配使用，只有当shuffle=True的时候，才有意义。 因为只有随机起来，每次结果不一样，为了重现，才利用seed.如果shuffle=False，每次split都是按照顺序来划分，想要重现无非就是重新运行一下罢了。 Webb27 mars 2024 · 29 апреля 202459 900 ₽Бруноям.
