Watermelon 3.4 problem solving report (python multi-class learning ten fold cross)
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 ...

Pervasive Technology ｜ how to use isolated forest and nuclear density estimation for anomaly detection?
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 ...

Machine learning - k-NN idea and implementation (based on Java)
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. ...

PyTorch implementation: classic network ResNet
Classical network ResNet
1 Brief description
Networks such as GoogleNet and VGG have demonstrated that deeper networks can abstract more expressive features and thus achieve stronger classification capabilities. In a deep network, with the increase of the network depth, the resolution of the feature map output by each layer is mainly reduced ...
