Starter Book List The beauty of mathematics PDFThe author Wu Everyone is familiar with it. The application of mathematics in the fields of machine learning and natural language processing is described in a very popular language. "Programming Collective Intelligence" ("collective Wisdom Programming") PDFAuthor Toby Segaran is also the author of Beautifuldata:the Stories Behind Elegant Data Solutions (t

All machine learning models are defective (by John Langford) Attempts to abstract and study machine learning are within some given framework or mathematical model. it turns out that all of these models are significantly flawed for the purpose of studying machine

Choosing a machine learning Classifier by Edwin Chen On Wed April 2011 How does you know the learning algorithm to choose for your classification problem? Of course, if you really care about accuracy, your best bet was to test out a couple different ones (making sure to try Dif Ferent parameters within algorithm as well), and select the best on

Li Hang, chief scientist at Huawei Noah's Ark lab, delivered a keynote speech. Li Hang, chief scientist at Huawei Noah's Ark lab Li Hang said: so far, we have found that the most effective means of AI research in other fields may be based on data. Using machine learning, we can make our machines more intelligent. At the same time, Li Hang believes that we need a lot of data to learn exactly how much data we

-learnIs you starting-in-machine learning? Want something that covers everything from feature engineering to training and testing a model? Look no further than scikit-learn! This fantastic piece of free software provides every tool necessary for machine learning and data mining. It's the de facto standard library of th

one of the simplest machine learning algorithms. The idea of this method is: if most of the K most similar samples in the feature space (that is, the most adjacent samples in the feature space) belong to a certain category, the sample also belongs to this category. IX,Naive Bayes Among the many classification models, the two most widely used classification model

and theories, especially for those who do engineering applications, the real need for mathematical knowledge mediocre, mainly include: calculus, linear algebra, probability theory, optimization methodLet's take a look at the following:CalculusFirst of all, Calculus/advanced mathematics. In machine learning, calculus is mainly used in the differential part, the function is to find the extreme value of funct

practice and understand some simple principles of clustering classification algorithms, you can write kmeans And Naive Bayes, because these libraries all have third-party libraries. If you do not need a large amount of data, you can directly use the sklearn library, which is especially convenient. If there is a large amount of data to be distributed, I only use mapreduce to write data that is not distributed and there are many ready-made libraries. T

Do not have to know it but also know the reason why. Refer to "machine learning combat".? ?\ (k\)-Nearest Neighbor algorith

decision on one input is Muti-task learning, and the other is learning a classifier for each category. When the sample data of each class is small, it is wiser to adopt muti-task learning, so that the characteristics of the image can be learned better, and when the sample data of each class is large, the multi-classification model can be used, so the accuracy of

If The NB conditional independence assumption actually holds, a Naive Bayes classifier would converge quicker than Discrimi Native models like the logistic regression, so you need le
