人工智能_量化交易_金融数据预处理
Project description
人工智能训练中,对于时间断层数据的处理工具包
process serial data for AI training
- 根据断点,分配数据集,保证训练数据的连续性 allocate data set according to breakpoints, to ensure the continuity of training data
生成训练数据(避开数据断点)
# 注意:
# 传入的数据必须指定时间列(或其他顺序列)
# 传入的数据必须已按顺序排列好
# Attention:
# You must specify the time column (or other sequential column) of the incoming pd原始数据
# The incoming pd原始数据 must be sorted in order
from datetime import timedelta
from serial_data_handler_zxw import 生成训练数据_避开时间断点, 时间列_三角函数化
import pandas as pd
csv_path = "/Volumes/time_serial_data.csv"
data = pd.read_csv(csv_path)
# 指定时间列为'收盘时间',
# 设置断点为2分钟,
# 即如果两个相邻的原始数据pd间隔大于2分钟,则认为是一个断点
# specific the time column named '收盘时间' ,
# and set the gap is 2 minutes ,
# it means that if the gap between two adjacent pd原始数据 > 2 minutes, it will be considered as a breakpoint
x = 生成训练数据_避开时间断点(data, column_timestamp='收盘时间', gap=timedelta(minutes=2))
print(x.断点)
训练数据index = x.数据划分_避开断点(input长度=100, output长度=100, step=1)
print(len(训练数据index))
# 如果您的数据间隔小于1秒,请做相应的乘法转换, 例如: 1毫秒的数据,请乘以1000,转换为秒级数据
# 时间列_三角函数化
# If your pd原始数据 interval < 1s, please do the corresponding multiplication conversion
# for example: 1ms pd原始数据, you should multiply by 1000, convert to second-level pd原始数据
# time column trigonometric function
data['收盘时间'] = pd.to_datetime(data['收盘时间'])
data['收盘时间'] = 时间列_三角函数化(data['收盘时间'], 周期=timedelta(days=1))
print(data['收盘时间'])
多尺度时间数据的对齐
import pandas as pd
from datetime import datetime
from serial_data_handler_zxw import 时间序列_数据对齐
data = pd.read_csv('/Volumes/AI_1505056/量化交易/币安_K线数据_1d/BTCUSDT-1m-201909-202308.csv')
# to datetime
data['收盘时间'] = pd.to_datetime(data['收盘时间'])
# 时间序列_数据对齐
数据预处理 = 时间序列_数据对齐(data, '收盘时间')
i = 数据预处理.查找_时间范围(datetime(2023, 8, 29, 16, 54, 0), 查找精度='1d')
print(i)
pytorch的金融K线数据预处理
from serial_data_handler_zxw import 金融K线_AI数据预处理 as kAI
# 输出注意事项, 使用方法
kAI.金融K线_AI数据预处理.help()
# 数据标准化
csv_file = "/Volumes/AI_1505056/量化交易/币安_K线数据/BTCUSDT-1m-201909-202308.csv"
x = kAI.金融K线_AI数据预处理(csv_file, 100, 100)
xn = x.标准化(x.pd原始数据)
# 适用dateset的__getitem__(i)的数据获取
x.dataset__len__(是训练集=True) # 是训练集=False时, 调用测试集数据
x.dataset__get_item__(i=0, data=xn, 是训练集=True)
