Python is by far the most popular language in science, due in no small part to the ease at which it can be used and the vibrant ecosystem of user-generated packages. To install packages, there are two main methods: Pip (invoked as pip install), the package manager that comes bundled ...
However, it has a limitation that the dataset is extensive and needs more challenges to be used in real-time. Unsupervised learning Jianliang et al. [11] proposed applying the K-means clustering algorithm used as ML in intrusion detection. K-means was used for intrusion detection to detect...
