[英]python LinearRegression make real time prediction
i received data from many captors I want to predict electronic failure with linear regression in real time (i want to add new values to my model)我从许多捕获者那里收到数据 我想用线性回归实时预测电子故障(我想向我的模型添加新值)
i have small example :我有一个小例子:
from sklearn.linear_model import LinearRegression
from sklearn.datasets import make_regression
#dataset
#X : Date in millisecond; temperature degree; humidity %
#y : 0= no problem; 1 = electronic failure
X=[[969695100000,15,10],[969788280000,30,50],[975042120000,20,3]]
y=[0,1,0]
model = LinearRegression()
model.fit(X, y)
# Prediction
Xnew, _ = make_regression(n_samples=3, n_features=3, noise=0.1, random_state=1)
ynew = model.predict(Xnew)
for i in range(len(Xnew)):
print("X=%s, Predicted=%s" % (Xnew[i], ynew[i]))
i have real data X : Date;我有真实数据 X:日期; temperature and humidity and y, 0 => no problem, 1 the sensor has failed I have new data every days, i want to update my model every day.
温度和湿度和 y,0 => 没问题,1 传感器出现故障 我每天都有新数据,我想每天更新我的模型。
my goal is with this data to predict a sensor failure by tomorrow.我的目标是利用这些数据预测明天之前的传感器故障。
my question is: how add data to my model ?我的问题是:如何将数据添加到我的模型中?
i found solution for update model in realtime, i use partial_fit, i updated my code like this :我找到了实时更新模型的解决方案,我使用了partial_fit,我像这样更新了我的代码:
import numpy as np
from sklearn import linear_model
from sklearn.datasets import make_regression
n_samples, n_features = 10, 5
X=[[969695100000,15,10],[969788280000,30,50],[975042120000,20,3]]
y=[0,1,0]
model = linear_model.SGDRegressor()
for i in range(0,1000):
model.partial_fit(X, y)
Xnew, _ = make_regression(n_samples=3, n_features=3, noise=0.1, random_state=1)
ynew = model.predict(X)
for i in range(len(Xnew)):
print("X=%s, Predicted=%s" % (Xnew[i], ynew[i]))
i have last question, it's possible to predict y value with only date ?我有最后一个问题,可以仅用日期来预测 y 值吗? actualy for predict y tomorow i need to have all X data, it's possible to predict with only : X=[975042120100] without temperature and humidity, only date in millisecond ?
实际上,为了预测明天我需要拥有所有 X 数据,可以仅使用以下内容进行预测:X=[975042120100] 没有温度和湿度,只有以毫秒为单位的日期?
