, as shown in: Step 4: run the model. After completing the preceding operations, you can run the program. Click "run" at the bottom to run the model. After each module is run, a green check box is displayed in the upper right corner, if an error occurs in each module or step, a red icon will appear in the same place. After you move the mouse over it, an error type will be displayed. Step 5: view the result. Right-click the dot in the "Evaluate Model" box and select "Visualize" to view the mode

Application Recommendations for machine learningFor a long time, the machine learning notes have not been updated, the last part of the updated neural network. This time we'll talk about the application of machine learning recommendations.Decide what to do nextSuppose we nee

Recently saw a relatively good machine learning course, roughly heard it again. The overall sense of machine learning field is still more difficult, although Li Hongyi teacher said is very good, not enough to absorb up or have a certain difficulty. Even though the process ha

It also covers De Rham cohomology and Lie algebra, where audience is invited to discover the beauty by linking geometry wi Th algebra.Modern Graph theoryBela BollobasIt is a modern treatment of this classical theory, which emphasizes the connections and other mathematical subjects--fo R example, random walks and electrical networks. I found some messages conveyed by the This book was enlightening for my all in machine

corresponding to the numerical solution. Therefore, this solution is not the smallest solution that is solved step by step, as mentioned earlier by the PLA algorithm.Answer is the reason for more emphasis on the results, the direct solution is the mathematical derivation of the exact solution, so that the minimum solution is obtained, in line with the solution conditions, but also to solve the pseudo-inverse algorithm (this method is called Gaussian elimination method, see also Gauss, looked at

Python Machine Learning Theory and Practice (6) Support Vector Machine and python Learning Theory In the previous section, the theory of SVM is basically pushed down, and the goal of finding the maximum interval is finally converted to the problem of solving the alpha of the Child variable of the Laplace multiplication

Knowing an algorithm and using an algorithm are two different things. What should I do if I find that the model has a big error after you train the data? 1) Obtain more data. It may be useful. 2) reduce feature dimensions. You can manually select one or use mathematical methods such as PCA. 3) Obtain more features. Of course, this method is time-consuming and not necessarily useful. 4) add polynomial features. Are you trying to save your life? 5) Bui

intervention on the results of model training it's a lever. Model does not understand the business, really understand the business is people. What the model can do is to learn from the cost function and sample, and find the optimal fit of the current sample. Therefore, machine learning workers should be appropriate to the needs of the characteristics of some human intervention and "guidance", such as the h

First, the foregoingNumPy(numerical python abbreviation) is an open source Python Scientific Computing Library. Use NumPy , you can use arrays and matrices in a very natural way . Numpy contains many useful mathematical functions, including linear algebra operations, Fourier transforms, and random number generation functions . The Library's predecessor was a library for array operations that began in 1995 years. After a long period of development, it has basically become the most basic Python

of the current node is the middle half of the distance of all its leaf nodes is float (NUMLEAFS)/2.0/plottree.totalw* 1, but since the start Plottree.xoff assignment is not starting from 0, but the left half of the table, so also need to add half the table distance is 1/2/plottree.totalw*1, then add up is (1.0 + float (numleafs))/2.0/ Plottree.totalw*1, so the offset is determined, then the X position becomes Plottree.xoff + (1.0 + float (numleafs))/2.0/PLOTTREE.TOTALW3, for Plottree function p
