After tossing the crawler and some interesting content, I recently in the R language for simple machine learning knowledge, the main reference is "machine learning-Practical Case Analysis" this book.This book is a rare, purely r language-based

Tai Lin Xuan Tian • Machine learning CornerstoneYesterday began to see heights field of machine learning Cornerstone, starting from today refineFirst of all, the comparison of the basis, some of the concepts themselves have already understood, so no longer take notes, a bit of the impression is about the ML, DL, ai som

Learning notes of machine learning practice: Implementation of decision trees, Decision tree is an extremely easy-to-understand algorithm and the most commonly used data mining algorithm. It allows machines to create rules based on datasets. This is actually the process of machine

seem to be too many to write multiple logistic regression article. So I found the relevant information on a foreign site, but did not see the derivation process. The URL is: http://blog.datumbox.com/machine-learning-tutorial-the-multinomial-logistic-regression-softmax-regression/. He did it according to Wunda's theory, where J (Theta) is what we call the Ein.(3) Answer: the second17. Question 17th、(1) Test

Learning notes for "Machine Learning Practice": Draw a tree chart use a decision tree to predict the contact lens type, The decision tree is implemented in the previous section, but it is only implemented using a nested dictionary containing tree structure information. Its representation is difficult to understand. Obviously, it is necessary to draw an intuitiv

. It provides a convenient mathematical tool by building numpy and matplotlib on the basis of existing python. The toolkit includes a number of simple and efficient tools that are ideal for data mining and data analysis.In the home page, you can see the user Guide, which is the entire machine learning index, where users can learn a variety of effective methods. In reference, users can find specific usage in

If you are not a math department, don't look at this.Because the following is used to demonstrate the correctness of machine learning methods, you can use machine learning to get the results you want. For those who program or use this method, however, you can just use it with confidence and boldness. Just like you know

Where NumPy is a scientific computing package implemented in Python. Include: A powerful n-dimensional array object; A relatively mature (broadcast) function library; A toolkit for consolidating C + + and Fortran code; Practical linear algebra, Fourier tra

supervised and unsupervised learning, and stepping into core technologies such as classification, regression, clustering, and dimensionality reduction, and then explaining the more commonly used and classic algorithms, as well as advanced content such as feature selection and model validation. After completing this tutorial, participants will have a clearer understanding of the machine

The main learning and research tasks of the previous semester were pattern recognition, signal theory, and image processing, which in fact had more or less intersection with machine learning. As a result, we continue to read machine learning in depth and watch Stanford's

businesses and developers accelerate machine learning with the open source trusted Analytics Platform (TAP) Trusted computing platform. Tap provides resources ranging from big data infrastructures and cluster management tools, to model development and training, and application development and deployment.In terms of development tools, the Intel Parallel Studio Xe Tool Suite simplifies code design, developme

products, and so on, can be abstracted into vectors to allow the computer to know the distance between two properties. For example: We believe that 18-year-olds are closer to the 24-year-old than the 12-year-old, which is closer to the product than the computer, and so on.as long as the real-world objects can be abstracted into vectors, you can use the K-means algorithm to classify .In the "K-mean Clustering (K-means)" This article cited a very good application example, the author made a vector

-existing instances. This is very important and will be explained later. Now we have made some glossary to facilitate the subsequent presentation: (1) The concept or function to be learned is called the target concept and is recorded as c. (2) The concept is defined on an instance set, which is expressed as X. When learning the concept of objective, you must provide a set of training samples, which mus

initial cluster center, or each time with a different initial cluster center to run the algorithm multiple times, and then determine the merit.Although the two-K-means clustering algorithm improves the K-means, the common disadvantage is that the value of K must be realized, and the unsuitable K may return poor results. For the massive data, how to determine the value of K is the problem that academia has been studying, the common method is hierarchical clustering, or using LDA clustering analy

We are now starting to train the model, and also enter a number of parameters such as the following:The number of factors in the rank:als. Generally, the bigger the better, but has a direct impact on memory usage, usually rank between 10 and 200.Iterations: The number of iterations, each iteration will reduce the reconstruction error of the ALS. After several iterations, the ALS model will converge to get a good result, so many iterations (typically 10 times) are not required in most cases.Lambd
