dataset = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]shuffled_dataset = random.sample(dataset, len(dataset))print(shuffled_dataset)这个例子中,我们使用sample函数随机抽取了dataset中的所有元素,并返回一个打乱顺序的新列表。结语 本文详细介绍了Python中的sample函数,
DataLoader和Dataset是pytorch中数据读取的核心。 (以特定的方式从数据集中迭代产生一个一个的batch集合》 DataLoader DataLoader(dataset, batch_size=1, shuffle=False, sampler=None, batch_sampler=None, num_workers=0, collate_fn=None, pin_memory=False, drop_last=False, timeout=0, worker_init_fn=None)...
*persistent_workers(bool,optional) – IfTrue, the data loader will not shutdown the worker processes after a dataset has been consumed once. This allows to maintain the workers Dataset instances alive. (default:False)如果设置为True,对每个进程来数,当一个数据集被使用一次后,此进程并不会被关闭,...
datasets, weights=None, seed=None, stop_on_empty_dataset=False) 参数 datasets具有兼容结构的tf.data.Dataset对象的非空列表。 weights(可选。)len(datasets)浮点值的列表或张量,其中weights[i]表示从datasets[i]或tf.data.Dataset对象中采样的概率,其中每个元素都是这样的列表。默认为跨datasets的均匀分布。 se...

In this study, we developed a methodology to identify and remove noisy data from a dataset before addressing the classification problem of an artificial neural network (ANN) by proposing the use of the principal component analysis鈥搒ample reduction process (PCA鈥揝RP) to improve its performance ...
