IBM provides three advanced features of copy service1. flashcopy2. volumecopy3. Enhanced remote partitioning ing (ERM) This article describes flashcopy, volumecopy, and ERM.1) First, let's take a look at the description of flashcopy in redbook. A FlashCopy is a virtual logical drive that is a point-in-time (PiT) image of a real logical drive. the FlashCopy is the logical equivalent of its complete physical

(empirical Risk minimization) ERM, and the empirical risk is evaluated and calculated using the loss function.For classification problems, empirical risk, on training sample error rate.For function approximation, fitting problem, empirical risk, square training error.For the probability density estimation problem, ERM is the maximum likelihood estimation method.The least risk of experience is not necessari

1. Non-probability model vs Probability Model A non-probability model is a model represented by a decision function, and a probability model is a model represented by a conditional probability. 2. loss function (loss fun) VS risk function (cost fun) The loss function measures the quality of a model's prediction at a time. The risk function measures the quality of a model's prediction at an average value, which is assumed the expected loss of the model under the joint distribution. The risk

IdeasThe following is a concrete example of the implementation of this idea, such as the realization of 123 of the full array of combinations.Requires 123 of the full arrangement, can be divided into the following situations:Case 1: Full arrangement of the No. 0 place for 1+23Case 2: Full arrangement of the No. 0 place for 2+13Case 3: Full arrangement of the No. 0 place for 3+32The above situation is implemented in code as follows://Situation 1//In order to be consistent with the following, plus

Newton Method to Solve the minimum value and determine the unknown parameters. Logistic/sigmoid regreesion mode: By using a specific function, the linear regression problem is transformed into a classification problem, that is, by using this function, the value of Y is within the range of 0-1. Expected Risk (real risk)It can be understood as the average loss degree of data or the error degree of "average" when the model function is fixed. The expected risk depends on the loss function and prob

model 1 Basic knowledge In a relational database management system (RDBMS), data is represented by a collection of relationships. Characteristics of relationships in an RDBMS: name, attribute, tuple 2 operation of the relationship (1) Structured Query Language (SQL): A descriptive (not procedural) language (2) 9 Kinds of operation ① Insertion ② Delete ③ Update ④ selection ⑤ Photography ⑥ Connection ⑦ and ⑧ Sex ⑨ Poor (3) Combination of statements The SQL language allows us to combine the statem

collection operation must be the same, and the corresponding data type must be the same. The data tables in this example include student, SC, and course. For details about the data tables, see EXISTS and NOT EXISTS in the Mysql database.UNION example: Example 1.1 Questions: Students of the Computer Science Department and students not older than 19 years old. SQL statement: SELECT * FROM Student WHERE Sdept='CS' UNION SELECT * FROM Student WHERE SageQuery results: This query is actually a union

The data source of the gridview can be dataview, dataset, able, list, etc., as long as the data set conforms to the ilist interface. There is nothing to say about the first few items. What's important is that list is not commonly used.When list is used as the data source of the gridview, it must store a set of objects. Common ErrorsThe data source of the gridview with the ID "gridview1" does not have any attributes or features that can be used to generate columns.Causes and SolutionsThe cause of
