Lazy looking for the smallest data set on UCI, the data is about the speed and angle of the container crane, to judge its strength (I don't know the crane ah ah ah)
Although you don't understand it, it doesn't prevent you from writing code classifications. Obviously, markers are power, divided into 0.3, 0.5, and 0.7. Specific model learning or ...

Anomaly detection is to find data points that deviate from the specification. In other words, these points do not conform to the expected pattern. Outliers and exceptions are terms used to describe abnormal data. Anomaly detection is important in all areas because it provides valuable and actionable insights. For example, abnormalities in MRI s ...

k-nearest neighbors (k-NN) is a basic classification and regression method. Input: the feature vector of the instance, corresponding to the points in the feature space; Output: The class of the instance. When classifying, the new instance is predicted by majority voting according to the class of its k nearest neighbors of the training instance. ...

Time series model ARIMA
Application process of ARIMA model
The stationarity is identified according to the scatter diagram, autocorrelation function and partial autocorrelation function diagram of time series.
The non-stationary time series data are smoothed. Until the processed autocorrelation function and partial autocorrel ...
