Python Machine Learning Theory and Practice (4) Logistic regression and python Learning Theory From this section, I started to go to "regular" machine learning. The reason is "regular" because it starts to establish a value function (cost function) and then optimizes the val

of the most important aspects of machine learning is regularization and regularization, which will be detailed in subsequent chapters. Here is an intuitive understanding. The most common regularization item is the model of the constraint parameter. The following formula is used to constrain W: If y is a linear equation, the formula (1.4) is ridge regression. In Figure 1.7, we can see that the changed v

The following formula is used to constrain W: If y is a linear equation, the formula (1.4) is ridge regression. In Figure 1.7, we can see that the changed value can have a huge impact on the model. When M = 9 is still used, it can be better fitted by adding it to the regularization item. Of

(SVM) training algorithm can be classified into one of two categories after being entered into a new case, making itself a non-probabilistic binary linear classifier.The SVM model represents the training cases as points in space, which are mapped to a picture, separated by an explicit, widest possible interval to differentiate between two categories.Algorithm explanation: Support vector machine for machine

systems and robot control. Common algorithms include q-learning and time difference learning (temporal difference learning). In the case of enterprise Data application, the most commonly used is the model of supervised learning and unsupervised learning. In the field of ima

Draw a map, there is the wrong place to welcome correct:In machine learning, features are critical. These include the extraction of features and the selection of features. They are two ways of descending dimension, but they are different:feature extraction (Feature Extraction): creatting A subset of new features by combinations of the exsiting features. In other words, after the feature extraction A feature

problem solution.Or simply, it can be understood that finding a reasonable hyper-plane in a high-dimensional space separates the data points, which involves the mapping of non-linear data to high-dimensional to achieve the purpose of linear divisible data.　　　　　　The above sample map is a special two-dimensional situation, of course, the real situation may be many dimensions. Start with a simple understanding of what a support vector is at a low latitu
