2.7.x,python 3.3.X and Python 3.4.X four series packages, which is a legacy of other distributions. Therefore, in various operating systems, whether it is Linux, or Windows, MAC, it is recommended anaconda!Since Anacoda is a collection of Python science and technology packages, different packages follow the same proto
computing tools. So we excluded Scipy (although we also use it !).
Another thing that needs to be mentioned is that we will also evaluate these libraries based on the integration results with other scientific computing libraries, because Machine Learning (supervised or unsupervised) it is also part of the data processing system. If the database you use does not

If you are using a library that does not match the other libraries in your data processing system, you will spend a lot of time creating the middle tier between different libraries. It's important to

Selection of K valuesAs mentioned earlier, the number of clusters in K-means clustering K is a user-defined parameter, then how can users know if K is the correct choice? How do you know if the generated clusters are better? Like the K-value determination method of K-nearest neighb
