How to deal with time series data in PyTorch?

In PyTorch, handling time series data typically involves using torch.utils.data.Dataset and torch.utils.data.DataLoader to load and process the data. Here are the general steps for processing time series data.

1. A dataset from the torch utilities.
2. constructor
3. length
4. get item

import torch
from torch.utils.data import Dataset

class TimeSeriesDataset(Dataset):
    def __init__(self, data):
        self.data = data
        
    def __len__(self):
        return len(self.data)
    
    def __getitem__(self, idx):
        sample = self.data[idx]
        return sample

1. Data loader
2. group size
3. mix up

# 假设data是一个时间序列数据的列表
data = [torch.randn(1, 10) for _ in range(100)]

dataset = TimeSeriesDataset(data)
dataloader = torch.utils.data.DataLoader(dataset, batch_size=32, shuffle=True)

1. DataLoader is a tool used for loading data native to English.

for batch in dataloader:
    inputs = batch
    # 进行模型训练

By following these steps, you can work with time series data in PyTorch. In practical applications, data preprocessing and feature engineering can be done according to the specific characteristics of the time series data, as well as designing an appropriate model architecture for training and prediction.
