In machine learning tasks, data is often preprocessed. such as scale transformation, standardization, binary, regularization. As to which method is more effective, it is related to the distribution of data and the adoption of algorithms. Different algorithms have different assumptions about the data, may require different transformations, and sometimes do not need to be transformed, may also get relatively better results. Therefore, it is recommended to use a variety of data transformation metho
Python world is known for the machine learning library to count Scikit-learn. This library has many advantages. Easy to use, interface abstraction is very good, and document support is really moving. In this article, we can encapsulate many of these machine learning algorithms, and then perform a one-time test to facilitate analysis and optimization. Of course, for the specific algorithm, the super-paramet
