): A confrontational approach. The core idea of this approach is to add a small amount of noise to each step of the optimization process, allowing the predictions to be shifted toward the target category or, as you wish, away from the right category.Transferability Attack: Find an example of an attack on your own network, and this sample can often break other neural networks as well.3. The confrontation example can be used to train the network for better results.4. SummaryCS231N
Use the previous two articles about spring batchArticleYou should have a preliminary idea about spring batch. This article will use "Hello world !" For example, we will discuss some basic configurations and implementations of spring batch. Let everyone have a real understand
A recent project is using the Springbatch framework to make a batch of e-commerce platforms. On-line information is very limited, especially the Chinese information is less and less, official web documents are just some basic knowledge of getting started, most of the advanced features are a stroke, the explanation is not thorough, in the actual development encountered many problems. As a result, the process of learning and applying

A recent project is using the springbatch framework for Batch Processing on an e-commerce platform. There are very few materials on the Internet, especially Chinese. The documents on the official website only talk about the basic knowledge of getting started. Most of the advanced features are included in the document, and the explanation is not thorough, there are many problems encountered in actual development. Therefore, we summarize the process of
Spring batch is a lightweight, fully spring-oriented batch processing framework that can be applied to a large number of data processing systems at the enterprise level. Spring batch is based on Pojo and the well-known
With the introduction of the previous two articles on spring batch, you should have a preliminary idea of spring batch. This article, will pass a "Hello world! "Example, and discuss some of the basic configuration and implementation of spring
Compared with the traditional Batch Processing, although Spring Batch is quite different, in the final analysis, it is executed in sequence for some column tasks. You can use Spring Batch to read the content of a TXT file, and then put the processed data into the database, a

Because the script must start a task through the Java virtual machine, a class containing the "Main" method is required as the entry of the program. Spring batch provides an implementation that meets

. But you can also reload it:
Under specific circumstances, the task step configuration can contain other elements to help with splitting (4.1.1 restart capability
When a batch task is executed, it is important to note when it will be restarted. When the specified "task instance" already has a "task execution instance", running this "task" is considered as "restart ". Theoretically, all tasks should be able to be started. If they are not running, the
Schema for Spring BatchA batch job is a collection of ordered steps that are executed as part of a predefined process;Step represents a custom unit of work, which is the main component block of the job; each step consists of three parts: Itemreader, Itemprocessor, Itemwriter; These three sections will be executed on each record being processed, Itemreader reads each record and passes it to itemprocessor pro
The previous article about spring batch describes springbatch's read and write operations on flat, XML, and other files. This article will discuss with you spring batch's read and write operations on DB. Spring batch provides two methods to read dB data. One is to read data
The spring batch job has a lot of metadata at run time, which is typically stored in memory or in the database, because spring batch is configured to use HSQLDB in the default configuration, which means that all of the metadata is stored in memory during job operation. The end of the job will automatically disappear as
This article will use a complete example to discuss the use of spring batch to read and write CSV files. The process of this instance is: Read a CSV file (ID, name, age, score) containing four fields and perform simple processing on the read fields, then output to another CSV file.
The engineering structure is as follows:
The joblunch class is used to start a job, And the csvitemprocessor class is us

Noun Description:Context: Perform: To perform the context:Case:Warning: Once steps shares the data, the data will connect the steps together. Try to make steps independent. If you really cannot be independent of them, use the following techniques. You should use data sharing as a fallback option that steps cannot be independent.1 ways to share data:
A step stores shared data to the database, receiving step to read them from the database
Execution context (execution context): Use
ResultSet field to Java objects, but the columns of the datasheet must correspond to the properties of the Java object, there is no source of research, a bit similar to the Apache Beanutil, I wonder why this part in the Spring Development Reference manual does not, Isn't it a classic?
