Text categorization problem: given document P (may contain title T), categorize documents into one or more of the N categoriesText classification applications: Common spam identification, sentiment analysisText classification direction: mainly two categories, multi-classification, multi-label classificationText Classification methods: Traditional machine learning Methods (Bayesian, SVM, etc.), deep learning methods (FASTTEXT,TEXTCNN, etc.)The processi
The following example modifies the ecshop2.7.2 prototype as follows:1, the first need to modify the program files, the supplier read out, and then assigned to the template, Open File/goos.php, $smarty->assign (' goods ', N Bsp $goods); Add the following code if ($goods [ ' suppliers_id ') { $goods [' Supplie Rs_name ']= $db->getone ("Select Suppliers_name from" . $ecs->table (' Suppliers '). "Where suppliers_id=". $go
. Naive Bayesian classifier has two kinds of polynomial model and Bernoulli model when it is used in text classification, and the algorithm realizes these two models and is used for spam detection respectively, which has remarkable performance.Note: Personally, the "machine learning Combat" naive Bayesian chapter on the text classification algorithm is wrong, whether it is its Bernoulli model ("word set") or polynomial model (the book is called "word bag"), because its calculation formula does n

Scene:A public warehouse, stocked with supplier A's X1 merchandise 100 piecesVendor A's reseller B has bought X1 merchandise 50 pieces from the SupplierAt present, according to orders to get goods, there will always be a great uncertainty, all according to their own sales, pre-purchase 50 pieces of comparative insuranceHowever, you still want to store in a public warehouse, because it is convenient to ship (or public warehouse delivery, save freight)P
predict_proba should not be taken too seriously.
Another limitation of Naive Bayes is the hypothesis of independent prediction. In real life, this is almost impossible, and there are more or less mutual effects between the variables.
4 Applications of Naive BayesReal-time predictions: no doubt, naive Bayes soon.multi-Class prediction: This algorithm is known for its multi-class predictive capabilities, so it can be used to predict the probability of multiple target variables.text
For child window controls, sometimes we might want to get some messages from a subwindow, such as having three buttons under a main window, and if you want to use the Keyboard tab or the Shift-tab key to switch the focus between different buttons, you can use the Subwindow Class (window subclassing) method.Subcategory of child window:The window message handler for the button control is internal to Windows. However, by calling GetWindowLong with the Gwl_wndproc identifier as a parameter, you can

In this article we highlight the service layer. Because the DAO layer is the reverse generation of mapper with GYSYPML. So the service layer is the focus here.The business logic is as follows:1: We passed in two values from the front page: 1:usergysid (Vendor ID), 2:YPPXXID (catalog ID of the drug)Let's take a look at the table where we want to insert the data:All we have to do is insert the two fields.2: We look at the design of such tables:Here is a constraint, that is, Ypxxid and usergysid tw

(CJ) =n (CJ)/n,p (d (TI) | CJ) = (n (ti, CJ) +1)/(n (CJ) +m), where N (CJ) represents the number of text in the training text that belongs to the Cj class, N is the amount of training text, N (ti, CJ) represents the number of training text containing feature TI in the category Cj, and M represents the total number of feature items inJust calculate all categories of P (cj| D), and then which is larger, which category the document belongs to. 3.

In recent days to see a text categorization program, write the specific implementation process. Sometimes I see the algorithm, I feel very clear, but I do not know when to achieve. This time from a practical process, may be able to better understand.
