dimensionality reduction, model selection and data preprocessing (Project address: Https://github.com/scikit-learn/scikit-learn)4. PatternPattern is a Web mining module that provides tools for data mining, natural language processing, machine learning, network analysis, and network analysis. It also comes with complete documentation, with more than 50 examples and over 350 unit tests. The most important th

characters. Basically meet the use of various languages. In fact, the current version of Unicode has not been filled with this 16-bit encoding, reserving a lot of space for special use or future expansion.Implementation method: Unicode is implemented differently than encoding. The Unicode encoding of a character is deterministic. However, in the actual transmission process, because different system platform design is not necessarily consistent, and for space-saving purposes, the implementation

-domains, such as "machine learning", "Data mining", "Pattern recognition", "Natural language processing" and so on. These sub-areas may have intersections, but the focus is often different. For example, "machine learning" is more focused on algorithmic aspects. In general,

How to evaluate the assumptions we get from our learning algorithms and how to prevent overfitting and less-fitting problems.When we determine the parameters of the learning algorithm, we consider the choice of parameters to minimize the training error. Some people think that getting a small training error must be a good thing. But in fact, just because this hypothesis has a very small training error, when

IntroductionIn real life, we may unknowingly use a variety of machine learning algorithms every day. For example, when you use Google every time, it works well, and one of the important reasons is that a learning algorithm implemented by Google can "learn" how to rank pages. Every time you use a Facebook or Apple photo

This library was developed in my spare time and released based on GPL3. Some content in the library can be learned independently. for example, all codes are independent.

This way you can focus on the questions you're going to study on this data set, instead of distracting yourself from learning a particular technology or writing code to implement it.Some strategies that can help you learn about experim
